Performing this service engine in, is laborious. Having installed a new engine twice into my 2001 I can tell you with the right equipment, either a chain fall or a cherry picker engine hoist is faster and more important more precise than gimping in the valve springs. Dropping a valve into the cylinder is a night mare. I've tried the string approach but inevitably the compressor stopped and the valve slid into the cylinder. The gods were with me that day and I was able to repair the $99 Porter Cable compressor, wire had grounded out, and almost cost me an engine.

great points about the new and old valves, springs, and seals, and their respective weights. It seems like performance improvement is there for sure! The 4.7 is not the craziest v8 out there, but i think you are creating a monster!! 🎃⚡️💪
Awsome video thanks learn a lot from your videos ty. If I may ask you a question sorry to ask but I'm stuck maybe you can give me vise I have 2000 4.7 not h.o anyways I have changed lifters three times I have changed the timing chain and gear I have done exhaust manifold gaskets I keep fresh clean oil in it all the time I just cannot get rid of the ticking noise when I first started up ticks like crazy eventually it goes away but it's non-stop every time I started out I'm lost I don't know where else to go it's got good oil pressure but the oil pressure does drop as you drive it any advice would help to key in on a area I appreciate it thank you
Have you tried the zinc additive or an oil with zinc in it? It helps reduce the friction of the parts. It's not as easy to find, but it's not hard either.
You can still use the socket when head is on vehicle. We used that process on a Honda oddessey. You can use the same proccess to install the keepers aswell
Those differences would remove almost a full pound of valvetrain weight. I can only see that as a good thing. But im curious of the 08 spring rate vs the HO springs.? but good info thanks martin!
Currently rebuilding my 08 4.7 heads, well whole engine actually but purchased all new components for the heads and there is huge weight savings with the 08 parts. I bought new cams as well and each cam is right at 2lbs. Lighter than my original Oems. My originals were solid cams with the powdered metal lobes and the replacments are the hollowed shank with slightly narrower lobes with oiling holes which my oems were not... The profiles and journels are the same O.D so im just taking it as a performance gain I suppose.
Can those 08+ valve stem seals be used with the h.o. springs? I like how that style keeps the spring from deflecting. Or would you recommend running the 08+ spring/seal in place ofthe stock the 99-04 h.o. valve springs. Also just a thought, the 3.7 exhaust valve spring comes with a similar design that keeps the spring from shifting. Not sure what years but I saw them in an '04. I'm going to try and get a few to see if the h.o. valve springs will fit in them.
Hey Martin, just a thought, but something that I have done on another tool that had threaded holes in aluminum similar to your design, I drilled out and used heli-coils loctited in giving my aluminum tool steel threads.. just an idea 🤷♂️ Keep up the good work!
good question, I would think if the seat fell a small amount it may kick the rocker arm out. Unfortunately, there is no test that I can think of that would indicate that a valve seat is starting to fail.
Hi Martin. Would You check what kind of valve stem seal are inside plastic cup in 2008-2010 heads? I mean is it possible to dissmantle spring from cup and change only inside valve stem seal instead buy complete original set with valve spring? It would be useful for person watching You from other country where parts are much more expensive then in US.thanks a lot for your valuable videos.
@@martinbuilt yes ,i know that it exist as set with spring and is not possible to buy it straight es replecament only valve steam seal, point is that i think same valve stem seal what are inside de plastic cup could be used in other cars maybe as simple valve stem seal . So i would like to find which one will fit. Was looking in Autozone webpage and it shows Mahle ss46047 as replecament only seals. If You can remove it from cup and just compare it.
Hey Martin I have the same make and model Jeep as your WJ and was seeing if you could help me out. I have rebuilt my engine as a result of a head gasket leak and a broken intake. I have gotten to the point of reinstalling my intake manifold and I’m having a difficult time figuring out which vacuum hoses go where. The main one I’m unsure about is the nipple on the back bottom of the intake and where it goes, and where the hose that come from the oil fill goes. If you have a video of yours or a diagram you could reference me to it would be much appreciated. Thanks!
Martin, have you done valve seats yet? My 02 Limited 4.7 mildly dropped #7 intake seat, no damage. I was wondering how easy it is to drive the old ones out, along with guides? We used to do heads on 3.0 Mitsu's and other Mopar's by driving the old seats and guides out, freezing the guides and seats, heating each and driving them in by hand, hand staking the valve seats, then performing a complete valve job, grinding, lapping, new seals, mild port and polish on special cases. I was wondering if anyone can say whether its easier and cheaper to DIY the head job. have the machine shop do it, or buy 2 reman heads (I'm doing both heads to be safe).., on 4.7's we put new heads in under warranty, or when the motor ate itself, a short block and raw heads, then assembled with the old cams, rockers, new lash adjusters, basic valve job, and reassemble/reinstall. I can tell you from working in the dealer many years and owing 3 currently, 4.7's are not cheap engines to rebuild of repair, nowhere near as cheap as the LA's, Inline 6, or RB Mopar motors are/were.
@@martinbuilt I'm working on my end to address the actual problem, not just swap out existing failed heads for heads that will fail again, in some cases as soon as 500 miles with online head replacements. I'm waiting to hear from a Mopar centric machine shop experienced with the 4.7 valve seat issue, will pass on the info when I get it.. This particular shop is well know for its Mopar and Diesel head work on a national level and is close by.
Hello Martin. We have talked on this before. I am replacing the short block this spring in my 04 WJ, dropped a seat in number one. Beat up the piston a bit but didn't trash it totally, but the lower end has 165,000 on it and I feel it's time for a fresh one. I put remanned heads on it however I believe they didn't address the guides as I get a oil puff on startup after sitting all night indicating bad stem seals. I currently have the solid lash adjusters and HO cams with larger injectors. My question is do you know if the late valves fit earlier heads? I am having the heads done as well and I will probably hit the ports a bit with the die grinder as I cannot leave well enough alone. I have a set of 09 cams I got out of an Aspen 4.7 and they are going as well. I would like to put the later springs and seals in as well. Thanks in advance and say hello to your Michigan transplant friend, Rick I believe is his name.
Hello Charlie, yes the newer valves will fit the older heads and the seals and Spring should work on all but one valve where part of the head seems to crowd the seal a little bit but I believe that could easily be fixed with a cutting head and a die grinder.
I can't remember if all of the 08 pluses have an EGR valve or not but if you were to but say convert to the 08 cylinder heads you would just simply block off the EGR ports.
@@martinbuilt My 180K HO is still in good shape. In midst of stem seals and cam chain for preventative but a late 4.7L motor for future backup is on the agenda. Crank/Cam tone rings have to swapped. Not sure about second plug yet. Without your tool seals are a two man job!
it can be done, you will need the 08 exhaust manifolds and I believe the 08 injectors as well and I would use the 08 ignition coils and wires. I would like to try it but still what to use the Doug Thorley headers.
According to air ram theres no difference between the non H.O heads and the H.O heads they flow identical, is there an advantage to switching to the 2008 heads on a regular 4.7?
I can tell you that the intake and exhaust port are larger, the head is built better (stronger). I will be working on a video that gives cc's for the combustion chamber, intake, and exhaust ports and compares that to the HO heads.
Yeah you could go to the salvage yard and find yourself a good used one you may also want to grab the intake manifold as well especially if the valve seat dropped and broken to pieces there's a good chance some of those particles went into other cylinders. I would start with removing the cylinder head and find out just how much damage there is.
@@martinbuilt thanks luckily it only cracked but it did drop, passenger side head cylinder 2 dead obv but I got you thanks for the reply I'll try to find one that didn't have the same problem
I will verify this soon, they will bolt up. There are a few changes that need to be made, like the 08 exhaust manifolds will be needed and I would use the 08 coils as well with the coil wires that way both spark plugs are used. There is some other things as well.

Another great video. Really appreciate your attention to detail. Do you think a ZJ 5.2 V8 would run better with 180° thermostat?
