How to Install 4.7HO Camshafts & Solid Lifters in a Jeep Dodge Chrysler & Mitsubishi
HTML-код
- Опубликовано: 8 сен 2024
- This is a popular cam swap for a true HP gain with 4.7 HO Cams. This will work on all 1999-2007 Chrysler 4.7L engines. Detailed instructions on how to adjust solid lifters. The solid (lash adjusters) lifters are not required for the HO or the 08 and later camshafts but I would recommend them if you have the HO cams reground to correct rocker arm geometry. This would eliminate the need for shims under the lash adjusters. I got the Solid Lifters (Lash Adjusters) from www.airram.com Also shows how to remove and replace valve cover gaskets.

Im 20 years old and just got myself 2 jeep grand Cherokees a 2004 and 2003 V8 4.7 I love them and appreciate you so much man for real 🙏
Congratulations, I'm glad you found the content helpful.
Thank you for watching.
I would take them back and get 07-10 for a more fun time and meaner look unless you like rock climbing
I think the 4.7 is one of the most under appreciated engines on the planet. I've owned two of them (01 Dak/07 1500) and both were animals and served me well. my 07 1500 even towed better than my current 1500 Hemi. The bottom end torque they produce is outstanding.
I couldn't have said it better!
I've got two Grand Cherokees. 01 with 4.7 and an 05 with a 5.7 Hemi. They are both high milage and the 4.7 is a better engine by a pretty good margin. It's also just as fast despite being rated at 100 less hp.
You have to be joking, i went in my local machine shop the other day and there was these junk engines laying everywhere with holes in top of pistons on most of them where the valve seat fell out of the head. Never heard anyone say they were good engines lol. No offense, i hope yours last forever, i just would hate for you to get too far from home with it.
@@dreece2000 You didn't point out which generation of the 4.7 they were. My guess would be 1st gens. they had problems with valve seats. Gen II engines did not suffer with the problem and were the vast majority of the 4.7's used Dodge/Rams, Durango's, and Dakota's.. but dropping valve seats was not exclusive to the 4.7. Ford and Gm both had their share is nightmares with dropped valve seats, cracking, and so on (also includes those asian and euro products as well) until they got the recipe corrected.
@@dreece2000 Mines got 270,000 miles on it. Still tows and hauls great. These engines are far from being junk. Id take one of these over a 2v or 3v triton *any* day, and I'd even go as far as saying they are as good or better than their closest competition at the time, the 4.6 Ford Modular. Ive owned both. I didn't like being far from home in that stupid 4.6 Panther body. I had to keep spare ignition coils in the trunk and I was always chasing vacuum and intake leaks. It had a leaky injector that burned up both catalysts and left me on the highway. The 4.7 has been better in every way in my experience. No engine issues in all those miles.
Good video. The only video I've found showing lifter adjustment.
Thank you, glad you liked it.
Good job sir. Coming from a 18 year dodge mechanic. Dont forget the 2008 cams work excellent too 👍
Thank you, funny you mention that, I was installing 08 cams over the weekend with new valve stem seals Springs and retainers.
@@martinbuilt Haha nice, they come out better than h.o cams. Nice strong pull above 5k.
@@Gen3HemiBuilder1964
That's what I hear, got the 08 intake manifold installed and a custom 75 mm throttle body I built.
@@martinbuilt that's awesome, I'm about ready to do my father's 4.7 Dakota for him. A 75mm would be really nice on it. I scored a 08 intake manifold for him for 60 bucks.
@@Gen3HemiBuilder1964 yeah the combination of the intake and the 75 mm TB gave me the wow factor. Here is the video for the TB ruclips.net/video/HbNrOz74AXY/видео.html
Great Video Man!! Love the detail and how descriptive it was! Now I’m considering doing this to my 02’ Dodge Dakota 4.7
Where do I find Mopar cams for the same vehicle
From any 2002 2003 and 2004 Jeep Grand Cherokee limited or overland with the j code. the 8th digit in the VIN number needs to be a j@@peytonthepianoman
I just finished doing my 04. Put 08 cams in while I was at it. If you're thinking about doing this I can highly recommend it. Be warned, it is quite tedious getting just the right lash clearance. And you cannot just make all the same length. I set the lash .0015 - .002 and the lengths of the solid adjusters varied from the shortest being 1.934" and the longest being 1.952". Also, the threads are not real fine so a little turn changes the length quite a bit, and also tightening the lock nut will have the length grow about .0005 Makes getting as close to possible to .0015 lash quite the chore. Well worth it though. Dead cold start and.....silence!! So nice not to hear the clatter on cold start not to mention how much smoother the idle is, and the bonus of a quite noticeable top end increase.
UPDATE! My PCM decided to retire so I lashed the adjusters again, a couple started getting noisy again. When I checked them the .0015" lash grew to over .002, I also noticed on the base of those adjusters the wear marks were different than the rest of them. They showed localized heavy loading vs the consistent pattern on the bottoms of the ones that maintained the proper lash. My theory is the bottom of the bores the adjusters sit in are not machined very smooth, this was confirmed by looking in the bores. I think the constant pounding of the cam pushing the lash adjuster down during valve actuation pushes the lifter down with more force, not being a hyd cushion the bottom of the adjuster is very slightly flattening down the high peaks the bore cutter leaves in the bottom of the bore increasing the depth of the bore and requiring a lengthening of the adjuster to compensate for the increase in bore depth.
Way to go, Charlie, couldn't have said it better myself.
Going to be doing valve seals on my 03 Durgano. I won't be messing with the cams, but this is an excellent guide for removal of the valve covers, rocker arms, and lash adjusters. Thank you!
Glad it helped
Love your videos. I really do love my 4.7HO... In my 04 overland... Plenty of power... And underrated it's a smooth engine... And I drove a hemi and honestly seat of pants feel goes to the H.O.
Thank you, I agree the 4.7 is underrated and has great potential. I have a 4.7 HO on the stand that I will be rebuilding with lots of goodies. Thanks for commenting.
I have a 4.0 WJ, you got me hankerin' for a 4.7 WJ. Got my eye on an 02 in blue
4.0 will last forever but that 4.7 has some giddy-up and go. Good Luck with the 02
Also another trick I had handy...I had a pair of real long bent nose needle nosed pliers that I got in a set from TSC real cheap and they work absolutely perfect for popping off the rocker arms
Yeah I can see where that would work well.
I tried it at the junk yard before I tried it on mine...worked wonderfully...and since they are long and bent nose, they work for reassembly too
I think you are the best mechanic I've ever seen... amazing
A while back you told me that if I was rebuilding my motor and had the heads off and was planning on doing HO cams, that i should go ahead and do the whole upgrade and put HO heads on as well...
I searched for an HO motor ever since you said that, apparently these motors are very hard to find in my area...but TODAY I GOT THEM!!! In snow and heavy rain and a period of hale I worked my but off and got those heads HAHAHA
I remember the power our Durango had with a stock 4.7l so I am extremely anxious to get this not back in my truck with these upgrades...I am also hoping to do the intake manifold from the 08 jeep and am working with a guy at Shapeways to get a special filter housing cover made so I can use the snout Style scoops on the hood of my Dakota for "ram air"
Thank you so much for all of these videos...this is my first total engine rebuild and you have taught me so much and made this rebuild a breeze.
That's awesome that you found a set of heads. sucks it was in crapy weather.
Ah well it happens...did we ever get actual numbers on the HO amd torque increases for this? Also was wondering if you would use the HO fuel injectors or the stock ones? (Mine is a 2000)
@@Kolonol1 As far as I can tell the injectors are the same from non-HO to HO engines they all came with the 145's
@@martinbuilt oh ok because I was reading something about them have 3.3psi more or something?
@@Kolonol1 Yeah, I've heard that. I'm calling that BS
After watching your video, I think I could do this, I have a couple other little projects first but I could definitely work this out for next year😁
Thanks I'm glad you liked it and found it helpful and gave you the confidence that you could do this. 😊
I noticed the min is now .002 and max .004 on the ones I just got. I was going to shoot for .003 but after hearing your comments at the end I'll go for .002 I wanted to add, I have an old Harley ironhead Sportster that uses a similar valve tappet as far as adjustment. They use a ball on both ends so a feeler gauge is out, they are adjusted by how much resistance spinning the pushrod gives. I have found when I get the right lash and then tighten the lock nut it changes oh so slightly the length of the tappet. I am finding this now doing these. On my Sportster I go slightly longer and the tightening of the locknut sneaks it down to the desired length, I found that method works pretty good doing these also. I am in Michigan, not as hot as LV, I used to live in Phoenix, but it is 90 and muggy right now. I am on my third one taking a break feeding the dogs right now.
yea I like .0015 to .002
After you do your test fit you can split the difference from your feeler gauge and lenghten or shorten with your calipers until your right where you wanna be.
Well I commend you for your perseverance on the whole job,, it’s definitely a task!! I’ve contemplated trying to get more power out of my 4.7 Mitsubishi Duro Cross,, my situation is I need more power than I can get from headers and solid lifters!! I was given a nice RV and it’s just too much for the pickup to pull !!! My thoughts are since I don’t get any kinda mileage from the 4.7, I’ve a mind to just swap out the motor for a 5.7 Hemi and just install the HO components before installation!! I know it sounds good but I’m sure there’s a lot of hindrances the come with that line of thinking!!! But you did a great job,, thanks for the tips!!!
I have a 2005 Dakota and I’ve recently done new timing chains and head gaskets. That chain wedge tool will be ordered and in my tool box soon. Maybe those HO cams are in the future. Great video!!! Thanks
P.S. word to the wise
I ordered the timing chain master kit from rockauto and everything was good, but the sensor wheel on the passenger side was incorrect causing cam sensor code P0340 to show up on a scanner. I had to take the front of the engine off twice, because I didn’t notice the difference in that wheel. A 2005 Dakota has a N code and a J code and there’s the HO 4.7 so there was no choice in these two different vehicle codes. Pay attention to the VIN.
When ordering a timing chain set if you're PCM has 3 connectors it is a JTEC and if you have 4 connectors then it is an NGC these are the ways you tell the difference between the 2 Cam gears on the passenger side. Your 05 is definitely a NGC 4 connector PCM.
I've got a 2013 Ram 1500 with a 4.7 and would be interested in doing this also. On a side note I immediately recognized my old neighborhood on your test drive 😃
I grew up in hendertucky!
Are you still in the Vegas area? Your 2013 has better cams then the HO's. I will be installing the 2008+ cams soon with the HO springs.
@@martinbuilt Ok, this is the first 4.7 I've had. Are these a pretty good engine longevity wise? I've heard things about them dropping valve seats?
@@martinbuilt Yes, still in Vegas too
@@DieselTechBryan personally I like the engine. I love going to pick a part and so far I've seen 2 4.7 s that were in there because of valve seat dropping. When I bought my Jeep the previous owner basically lied to me about any major engine repairs. And then I found out that one of the cylinder heads had been replaced I would imagine it was for that reason. I believe if you keep up on the oil changes and run a high quality engine oil in it that this engine will last you a long time.
Absolutely the most helpful video on this topic. Thank you!
You're very welcome!
@@martinbuilt I recently purchased a 2003 dodge ram 1500 4.7 and it had a tick to it. I searched and searched Until i came across this very video. Thank you for providing such details. Changed my rocker arms, hydraulic lifters with no problem.
What is your cash app. Or a way for me to support your channel.. Thanks
I’m going to be in your neck of the woods on the eighth and ninth to inspect a couple new bridges that are built. Here it’s going to be very hot.
Yes it is very hot It looks like it's going to be the hottest June on record.
Excellent video and description - WELL DONE!! I'll be referring to this video while installing new lifters and rockers on my 2006 4.7 Durango SLT It started knocking yesterday - hopefully this procedure fixes it.
My ram did same thing I'm doing same process now lol
I was gonna say, I wonder if you kept stock hydraulic lifters and went with roller rockers if you'd get the same HP but less lopey.
I finally found some HO camshafts. Been looking for 2 years, used online for like $200 and new... no one can find them. If put a HO jeep into any parts website they give same dimensions for the standard cam size in a regular jeep. Anyways I found a set at a junkyard, got them for $40!
New HO cams? Excellent price for the junkyard ones at $40
I wrench on my own vehicle because frankly not many mechanics know what they are doing. I would have no problem in handing Martin my keys and say have fun... Or I'd even be with him working on it. He knows what he's doing and not many people that wrench on vehicles actually do.
Thank you, I really appreciate that. 😎👍
So many ways to F this up. Don't rush it. In high school we did my buddies 327 Mustang and left a washer under the valve covers. It stuck an intake valve closed and we wound up grenading the motor.
I recently installed the cams but not the adjustable lifters. I did buy OeM style replacements made by enginetech. The roller wheel in the rockers are the same as the cam lobe width whereas the mopar OEM are much narrower and in time will create a wear pattern on the lobes.
installed HO cams in my 2001 durango today and your video was very helpful! keep up the good work boss
That awesome!
Did it add any noticeable power or no? Looking to do it on my 04.
@@connercaraway6315 Yes, you will notice the difference.

Nicely done. Butterflies in your gut when your loosening the cam bolt. I know the feeling. Thank you.
Martin, please provide the information on the updated rocker arms and lifters for the 4.7. I have a 01 Durango and the lifter are ticking at start up. Thanks and keep feeding us with good info.
I have a 2001 dodge dakota with that engine might only have 30,000 on it
You're the best to Jeep's
excellent 👍 if your youtube videos had the option of subtitles in Spanish you had more subscribers greetings from mexico 🇲🇽
Thanks for the tip!
The real reason that the valve seats fall out is because the catalytic converters get stopped up and the heat backs up to the head and the aluminum head will expand and the seat falls out you can take the head to a machine shop the bore the opening and press a new seat in the fulcrum falls out because chrysler missed the mark and drilled the lifter bore 2mm to deep and the damn things fall out constantly i actually got some caps from a race team that fits on top of the valves to take up that gap.
Hi Martin, I'm driving a '03 Dakota 4.7 of course. There's an '08 Durango at my pick-a-part. I want to do the modifications you mention on your channel, but my question is: should I take the heads off the pick-a-part vehicle, or just the cam shafts and rockers? Will the whole head be compatible with my older 4.7? Is there any difference between the '03 and '08 heads besides the spark plugs? TIA
Yeah there is some more differences in the 03 to 08 cylinder heads you would also need the exhaust manifold's, the fuel injectors and I would use the 08 coils and spark plug wires as well
one other thing that would happen is you're gonna lose compression because the combustion chamber on the 08 is larger than the earlier models.
The valves are the same size but the intake and exhaust ports are larger on the 08 I'm not sure what the actual end result would be as far as performance, fro. the loss of horsepower.
You would also need the valve covers those are also different.
I would just recommend grabbing the Cam shafts.
Now if that was a good running engine at the salvage yard I would grab the whole thing and put that into your 03 and you would probably only have to do some exhaust modification. And a small wiring changes on the Ignition coils.
@@martinbuilt thanks for your input. I think I'm just going to go for the camshafts. How do I know if it was a good engine without getting too deep into it? The camshaft bearings will have some insight I suppose...
This was a very easy to listen to guy ,very detailed & clear instruction ,Great job on this video, Guy!
Thank you I'm glad you liked it and found it helpful.
Again,, great video !!! I forgot to ask in my recent comment the question, what 4.7 motor comes stock with the solid lifters and roller cam!!!
I know this video is quite old but could you make a video about how to get to the head gasket? Im no mechanic but im trying to replace mine
YOU make it look easy! Seems like you come across more HO motors used in Pick-A Part yards out there than we do here in Pennsylvania. I've been searching for a set of HO cams, or better still complete HO heads with cams to rebuild for my 2000 SLT Durango 4X4 I'm doing a mild refresh on. 150K on the clock, I've owned it since brand new, so this is preemptive, not because of any issues, other than rusted and broken exhaust manifold bolts and heat shields. Would you be interested is selling a set of HO cams or dare I ask heads? Again I only ask as they seem scarce as Hens teeth here. Having driven my HO 2002 Grand Cherokee Limited with the same gears, I want the extra HO power for my Durango as well. What a difference, feels like a lot more than 30 horsepower, though the Durango is heavier than the 02 GC, but the gears are the same. Was toying with putting 3:92's in the Durango as well with the cams and a tune.
Hello Phil, All of the Durango I've seen so far all have 355 gears in them it would be nice to find a set of 392 that is the same gear I would like to install in my Dakota.
The grand Cherokees with the 4.7 as far as I know all came with 373 pretty good gear, even though I may change those out to 392 possibly 411.
I do have a set of HO cams available if you like to contact me on my Facebook Messenger there is a link in the description.
@@martinbuilt Will contact you there. Thanks Martin!
Going to use this video to help me with lifters and rockers.
Can you install HO cams without head modifications
You sure can, remove and replace
@@martinbuilt I'll give it a shot. I've dropped 2 fulcrums for no apparent reason. I think cams may be low. Already replaced lifters (hydraulic), so I want to go solid to control lash. Does this make sense? Thanks for your response.
Great job! Your video will help me out a lot. Getting ready to remove me 4.7L to replace all gasket and sensors . Both of my 2001 and 2000 Jeep grand Cherokee limited are not high outputs. Q’S. Are the high output head valves bigger?
Looks like Vegas.?
Thank you I'm glad you like them and find them helpful. No the valves are the same size throughout the history of the 4.7 99 through 2013.
Yes it is Las Vegas.
Спасибо за отличную работу и информацию!
I'm glad you liked it and found it helpful. Thank you for watching.
Greath job brother, you´re are an artist....!!!!!!
The 4.7 is a tragically underrated motor. My 2008 Dakota still smokes almost anything that tries me. Design wise it’s Practically a hemi.
yeah it's what they call a Semi Hemi, I love this engine!
I have a 2006 4.7 grand Cherokee can I install the ho cams as well
I think that using the plastic cutting boards for making that wedge may just work perfect. Would my 2003 3.7 Liberty be this same set up. It starts knocking after it warms up¿?¿‽
Yeah a cutting board would work perfectly for making that wedge and it would be the 3.7 would be the same setup.
That knocking could also be a hydraulic chain tensioner
You make this look too easy! This is Excellent! I read your introductory comments, what are the advantages of using solid lift vs. stock (I'm assuming hydraulic) lifters? At some point I would love to do this to my 2006 jeep commander 4.7
The solid lifters have a few advantages a higher RPM potential especially if you're into a lot of horsepower modifications. You'll never have a lifter collapse like you will with hydraulic. No she you're not into having to pull your valve covers off every 20000 mi in readjusting them then I wouldn't recommend them.
@@martinbuilt any mods to the fueling needed with the cams? Seeing clearances to the wider spec is what I usually do, motorcycles and such. It is a bigger pain in these engines to check the clearances though.
Thanks man, this will help me a lot.
I'm glad you liked it and found it helpful.
@@martinbuilt I just bought me a nice 01 4.7 WJ. My first one, the engine runs smooth (no weird noises and healthy acceleration, EU version since I am from Poland, 165k miles on the odo) but there is oil leaking from the valve cover and thus I decided to take matters in my own hands and fix it myself (I am a true noob to be honest).
Bought the FEL PRO gasket and 16 brand new hydraulic lifters.
One question Sir, you said when reassembling the cover there is no need to use a torque wrench?
Also would you recommend putting some kind of special lubricant on the gasket or just cleaning it with alc.?
Nice to know I can use the same gear!
Right on!
Cool !! excellent video , good teaching . .. keep the good work man 👍👌
Thank you appreciate it.
Thanks for the great descriptive video. I have a few questions. Do you have to use solid lifters when you install HO camshafts? How has the Jeep been running since you put in the HO cams? will this upgrade cause a check engine light to come on? Will it affect smog checks (CA resident here). I have to replace my head gaskets on my '03 Ram 1500 with the 4.7L soon and I'm thinking about going all in and doing everything from timing chain to this HO cam upgrade. Thanks.
You don't need the solid lifters. It will not cause any checks light and no problem with CA smog.
@@martinbuilt Thank you for the speedy reply Martin.
Good clean job Martin .
Thank you Safwat
Ola, tudo bem? Você confiaria taxar este motor para rodar no álcool ? Por exemplo 12 de taxa ? Sera que as cabeças aguentariam a temperatura constante proxima dos 90 graus ?
Why don't you take the cam shaft off before the rockers? It seems like the rockers would just come right off as you are loosening the cam shaft bolts.
For sure the tighter the tolerance the extra little bit of smoothness. It really pays off if you go solid.
Can. These HO camshaft be used on the 3.7 liter of this motor. Thanks. Any experience on sway bar?
Thank you Martin....
You're not supposed to turn the crank backwards. I seen where you felt tension.
He was just rewinding the video
Could you use the factory lifters with an HO cam? Would there be any problems with the valve train if you used factory lifters?
You can absolutely use the factory lifters yes go for it

Benefits for the solid lifters
So you can use the stock springs???? Please let me know. That's the last Peace of the puzzle.
I will be doin...
Port and polish,
head decked,
ho cams.
Header's...
Can use a Ls1 92mm or 102mm with TPS and iac throttle body with adapter plate with modified plate..
2009 intake manifold. 27lb injectors.
custom tune and dyno.
3 inch dual exhaust.
Yeah you can get away with the stock Springs.
With all your modifications that you've added or are going to add you may want to go with the Comp Cam Springs I think I have the part number listed in the description.
That is a nice sounding Jeep!
Thanks Gary, hopefully someday it will sound even better once I get that HO engine built and installed.
What if you measure the valve clearance before taking off the old rockers and lifters and couldn’t get any of them to slide in between? Tried all between .002 to .004 and nothing fit in between old the rockers and lifters
The old lash adjusters are hydraulic. There should be no Clarence at all with them. You need to install your rockers and solid lash adjusters and then check the clearance and make adjustments by removing them.
It takes hours to get the adjustment correct. I would try to get it down to 002. If you settle at .004, you're going to have a noisy engine.
When I do the adjustments, I get it all down, too .0015
Because, as the engine warms up, the gap actually grows between between valve stem and rocker tip.
Martin, I know this is an older video. Wondering how you liked the solid “lifters”. They every come loose on you or need adjustment?
Last winter I ordered, then waited for Melling brand lash adjusters to come in because I believed them to be a good brand. They are now not staying pumped up. Might even have one or to not fully pumping up ever. It’s only been 7k miles. No dirty oil in the crank case, probably every, previous owner was meticulous. Didn’t see caked oil or dirty anything when installing HO cams.
All the noises went away after replacement, first time I hammered on the truck the tick came back and hasn’t left.
Not sure I wanna go solid lifters. Any other brands you recommend if they won’t replace these for me(and they prob won’t, it’s been a year even if only 7k miles)?
Thanks for all you do Martin
I like the solids but they are a lot of work to adjust them. I haven't had to adjust them since installed. If you do go solids tell Nick I sent you.
How do I rest timing marks on camshafts if the rolled out of position?
I have a 2003 dodge durango with the 4.7l v8 does anyone know where to find the cam bearing caps for the right bank ive looked everywhere i know of.
Martin, I love all of your videos. You do an excellent job. I would like to do the 08 cam and intake swap with the larger Throttle Body, 12 port injector upgrade on a non-HO engine. Will this mod work ok on a non-HO engine and will it pass emissions testing ok. I live in Arizona and they require emissions testing for registration.
Yes that will all work just fine my Jeep Grand Cherokee is a non HO engine.
And I have no problem passing emissions.
Would that Timing Wedge work on the 2008-2013 16 spark plug 4.7L? Thanks for the video.
Yes that timing wedge should work for the 08 and later models as well
Hey, martin I have a 4.7 crank no start...CPU says the PCM is good. I have changed the camshaft, crankshaft, alternator, battery, Map sensor..also I hear the fuel pump engage when I prime it, there is also pressure in the line and it occasionally starts but dies right out. I started doing the work because I found out the mechanic was just a parts changer robbing me. please help, thanks
That was fun thank you
Nice vid! I have a 2007 Dodge Ram 1500 and a set of the ho cams. Could I simply just swap the cams without messing with the valves/lifters? I’m trying to decide whether or not I should take it to a shop. Thanks!
Yes you can simply swap out the Cam shafts without changing lifters or Springs.
Thank you for watching
I have a 2012 1500 Ram pickup 310 hp and 330 torque . Also high flow exhaust muffler delete and superchips F5 tuner 93 octane tune also 16 spark plugs. Will h.o. cams help with more h.p. and torque ?
When you use an HO cam! Must solids lifters be used ? Also can i put on the HO heads HO cams on to a normal 4.7 jeep WJ ? Using the tone wheel from the stock 4.7 cam on the HO cams.
Thank you i like your videos very much you do a great job of showing how its done.
Thank you, you can use the stock hydraulic lifters and you can install the HO heads on a non HO engine. Yes use your stock cam gear if you are installing this on a NGC 4 plug ECM.
Should I replace cam along with lifters if cam lobes are slightly scored?
unusual to see the lobes scored if the bearing surfaces on the camshaft are scored that is somewhat common depending on frequent oil changes or not.
If one of the rockers fell off and that's why you are changing the lifters and it did some damage to the cam and yes I would probably change that out.
What's the best kind of spark plugs to put in the 4.7. And all so the coil packs.
Are all the lifters and rockers the same? As in, do they need to go back in the same order? Thanks
Hi Martinbuilt,
I'm Brazilian and I'm your follower and I also admire you a lot. I have a similar one to your JEEP, year 2000 in burgundy color and that I also do maintenance myself. Congratulations on your videos and they teach me a lot. I ask: - Have you thought about adapting Hydrogen generator kits (HHO Kits) in your Jeep? Acknowledgments.
Brubacker Dos Santos
Thanks for commenting and the kind words I do appreciate that. No I never have thought about doing the hydrogen generator I really don't know anything about it. It seems so hard to convert things when it comes to fuel injection and dealing with the onboard computer.
Why the hxxx did you put the chain set on with the lifters on ? !!!
Great video I learned a lot Big help thank's
Have you considered installing the prothane bushings front n' rear? Video?
I did build these rear lower control arms that worked out great.

@@martinbuilt my rig is mostly my street driver. I used Detroit Amazon brand components throughout.
I cant tell you how much your videos helped with some nagging issues. Especially the anti-sludge piece. Solved a severe smoking issue and oil burning. Turns out you were right I was using the low end donkeyToy branded (?) Unit $17 dollars. What could go wrong? Plenty as it turns out. The $70 Standard Part 2008 unit was just the ticket. 👍
Very detailed explanations as always. How much cussing do you have to edit out of your videos if any? You are always so calm. A few words would escape from me I think lmao. I love your jeeps and the mods you do.
lakrabid I don't recall cursing on that one I always do edit that kind of stuff out. You do have to have some patience with those solid latch adjusters though
martinbuilt aren't the lifters supposed to compress down just a hair and spring back up... mine are old and Frozen in the up position.. that's not a good thing there's supposed to have a little compressibility.. I'm really confused how to solid lifters work without slinging and pushing out the rocker arms...
steve mitchell I adjusting the solid lifters to the proper clearance. The hydraulic ones adjust automatically but you do lose some lift so you lose performance with hydraulic. they also have a slower closing rate. I just went out and checked all my old hydraulic ones they are all as you said frozen in the up position and they were working just perfectly fine. I would be more concerned if you could actually push them down
martinbuilt you are supposed to be able to push a lifter plunger down but it's supposed to spring back up there's a spring inside if it stays in the down position that's a problem or if it stays in the up position that's a problem.. there is supposed to be about a .50 valve lash cushion... if the lifter is stuck in the up position when the cam lobe comes around and pushes on The Rocker it's going to push too much force on the rocker arms and wanting to spit it out... if the lifter spring is busted lifter plunger in the down position when the cam lobe comes around now the Rockers way too loose and it can get spit out... that's why it's important for the lifters on those goofy ass 4.7 and 3.7 valve train design to be in good shape..
just noticed you are in Henderson, I am by sunset station, cool ride
Yeah, I'm about 5 minutes away from there I go to the Henderson Pick-A-Part all the time.
@@martinbuilt yeah. Me too I go to both of nvpap and a couple of other ones. I am actually about to go there today. They put a few new jeeps a couple of days ago. You know i have a friend that has a jeep and asked me if i can so a lift on it and i did a 4 inch rough country on it. Drove the car before and after and what a difference. And I always wanted one. And got my first one, an 03 with 148k and the 4.7 HO. But has issues to be fixed. 1 door does not open. Has a check engine light on p0442 code.(I think i know where the problem is) and the knocking noise. And needs tires. But i will put some time in it. I Don't know many people with jeeps and the ones I know don't do their own work. If you want to check it out let me know im by Marks and Warm springs.

Hey Martin. Good video, but something puzzles me. You know ALL these engines were notorious for dropping their powdered metal valve seats. It's not a matter of if, but when on these 3.7, 4.7, & 5.7. They all do it. It would appear that it's already happened on that passenger side. My concern would be that you did all this work running the risk that the valve train could be damaged when this happens. Just wondering if you knew/know this.......
Nothing that I did is going to increase the chance of a valve seat dropping. I'm also going to take it as far as installing HO Springs and the 08 camshafts. I still have confidence in this engine, hopefully it doesn't prove me wrong.
I have a 2003 Dodge Ram 1500 with the 4.7l in it. Can this be done to any 4.7l Chrysler engine? Does upgrading to HO cams mess with emissions (I'm in California) ? Any check engine lights come on? Great video by the way.
Thank you Antonio, yes you can do this to any Chrysler 4.7 that has a single spark plug per cylinder, that would be all before 2008. I know this will not interfere with the emissions and you will have no problems passing California smog.
Great video!!!! but I have a question wouldn't it run better if you installed a 4.7 HO intake to match the cams??
In 03 all 4.7 came with the same intake if it was an HO or not. The 02 intakes might be a little better didn't have on at the time that I installed the HO cams. Since then I have installed the 08 intake with a 75 mm throttle body.

Great info but you should never rotate the crankshaft counter clockwise.
Doesn't matter if it's only a few degrees. Wont hurt that engine.
GREAT VIDEO FROM THE STATE OF PA
Thank you
if you adjust the lifter correctly you will not hear any lifter noise.
Hey Martin! Love your videos!
Got a question for you. Ive swapped Dodge Ram 1500 04 with Jeep's HO engine. I got 4 plugs on ECM.
Do i need to adjust fuel map on my ECM manually? I feel this new HO engine currently is less powerful than i had.
Thanks!
Thank you, that is the first time I have ever heard someone say they lost power with HO cams. I would place the ECM in a quick learn by resetting it.
Sure, airram.com has them and a guy by the name of Jay Greene deals torque converters too.
great video, as always! question, what do you think of the solid lifters? i know you said they were a bit noisy, did you keep them?
Yeah if you don't get the tolerances really tight like down to .0015 you're gonna get a little noise from them. And they are a lot of work to get them adjusted properly but once you do I really like them.
I don't have to worry about a lash adjuster failing and a rocker arm coming out and doing damage to Cam shaft and cylinder heads.
@@martinbuilt I am having troubles finding anyone selling them, do you know of anyone that still does?
@@KyleGreenhow Airram Performance
@@gooble1050 You found them! Thank you, but $390, yikes
When you stabbed it passing that mustang it was awesome. Which valve spring brand did you choose?
I'm glad you liked it. I kept the stock springs but after installing the 08 cams I replaced the springs with (part number 53020749AC)
@@martinbuilt I bet lot's of folks get a surprise rolling up to you in a Bronco or Tacoma. I'm sure you raise an eye brow!
I just need to install my 08 manifold and matched throttle body and fuel rail with the new 4 port injectors n' "fire it up!"
I used the comp cams mustang behives with the HO cams. I'll have those lasj adj ETC heading your way once I get Golden Bear running, tomorrow???
More footage of your awsome WJ!
What type of headers did you get to fit in there? I went through my 01 Limited 2 years ago, rebuilt from bottom up with .020 over pistons and about .010 off the heads, Superchips towing tune. Runs awesome and I am happy but I just ran across a 04 Overland with the H.O. and can get the whole thing for scrap. it starts and drives and runs but had no title and is pretty rusted out but was hoping to pull the cams and transfer them to my 01 and maybe swap the intake while I am there for a little more oomph. Thanks for the Video and information!
Doug Thorley Tri - Y ruclips.net/video/u6-Yl1z8auA/видео.html
Man that sounds nice... What exhaust are you running? Whose headers and pipe sizes?
Doug Thorley Tri-Y headers and 3" exhaust
On the 2nd coil pack from the front there is a sensor that is attached to the bolt...my 2000 Dodge Dakota has those but they arent hooked up...what are they?
It is a capacitor for the ignition coils. I would hook them back up
You do great expiations as to the parts and the tools needed.
Question MartinBuilt:
Is their any issues using HO pistons, connecting rods with bearings, HO heads, intake manifold, HO cams into a 4.7 regular 8th digit N. Not changing crankcase due to tone ring i will use my normal cam tone ring.
I ask because you do know alot of tricks on these 4.7 and the jeep grand cherokee
No there would be no issues doing that, you may want to just change the tone ring on the HO engine to a 32 tooth and the right cam sprocket to work with your vehicle and that way you also get the steel crankshaft.
Martinbuilt i may do that. Thank you for the fast reply and solid information. Was wondering if the tone ring was interchange. To correct ya take off the 32 tooth and replace with original 16 tooth tone ring...
Very explanatory
Hey Martin, can the heads be removed/installed without removing the cams?
Yes
I have a 2004 4.7 h o Jeep Grand Cherokee. My question is if I pull out a camshaft from the 08 Durangos will it increase the horsepower or should I just stick with the stock 4.7 H.O camshaft? And if I do need to pull out a camshaft from a Durango which model do you suggest?
It should increase power but may change the torque curve or when you feel the power. I would also install the 08+ intake manifold with a larger throttle body. My Jeep Grand the power really kicks in at 3200 past 6000 RPM
Any of the 08-13 Jeep, Dodge 4.7 engines with dual spark plugs per cylinder will work.
@@martinbuilt just checking... Does it have to be from the years 08-13, and only from the dodge and jeep 4.7 engines??
@@noemah3272
yeah all the 08-13 Chrysler, Jeep and Dodge 4.7 engines. These engines will have dual spark plugs per cylinder.
Hey Martin, @ 30:00 you begin installing the solid lifters. I'm doing the same install on a v6. My question is what is the target height of the overall lifter. You mention just over 49mm. Using your first lifter as the example I want to know if you readjusted the lifter off camera or at a later date want to ask if you had to change its measurement
You will definitely need to make adjustments to the lifters. And if you ever install a reground camshaft that will also make a difference. I spent hours getting the right measurement. Sometimes you have to take one lifter in and out half a dozen times before you get it right.
@@martinbuilt thank you for the reply and for posting this video! I just finished installing the slc on the passenger side. I tried to keep it close to .002. I dont have any lock tight on hand so I'm calling it for now and heading to the store for some. I did start it with the new SL installed on the passenger side. I think it sounded great, and with the two types of lifters I couldn't tell a difference in noise volume between the two. I'm pleased with the lifters, although I'm not looking forward to removing them again just to dab lock tight on them, but that's how she goes some times. I'm 5 or 6 hours into it. Do you have any advice on how to apply the locktight?
I actually did not do any Loctite on mine. I would remove them clean them up and place one drop or 2 at the threaded part.
@@martinbuilt again I really appreciate the response! Is there any concern reguarding the necessity of the locktight under the lock nut? Or can I get away with a dab on the outside top? I'd like to not have to reopen and readjust the lifters. Thanks Martin, I'm subscribed! Side note, have you had to readjust them since?
@@alexbrown8997 I would just a dab on the nut. No I haven't had to adjust them. Hopping to install the 08 camshafts soon.
Is it possible to just swap the camshaft? Without changing the hydraulic lash adjusters or rocker rollers?
Absolutely you can install the HO camshafts or 08 camshaft without having to replace lifters.
