![Gunna - today i did good [Official Video]](http://i.ytimg.com/vi/ulGLk8TaXcI/mqdefault.jpg)
just finished replacing the intake gaskets on my 97. Got to say, you're a life saver amigo.
I just finished this up. I got a bit of water in the valley, so I dumped the oil. Ran some new oil for the first hour of test. Now, it's time to flush the old coolant, oil, filter, and BOOM, done. Thanks again for helping me out. I took a pics as I went, but missed a couple important shots. Your vid had them. Very much appreciated this.
That's awesome good job man! glad it helped
Did this job over this weekend, plus upgraded to MPFI. Took my time, and cleaned the machined surfaces with a razor blade. Ended up breaking the heater hose fitting - had to chip it out and chase threads with a 1/2" NPT tap.
The bit about using a long screwdriver to back off off the oil pump drive to align the distributor gear was especially helpful. 96 K1500 Suburban 5.7. Runs like a champ - no more leaks and no CEL! Thanks for posting this video.
I finally did this job on my 99 suburban and I owe it all this great 2 part video. Appreciate the help- Thanks!
Awesome!!! I’m happy to hear this video is still helping people:) makes it all worthwhile
I'm watching this series for the second time, you mentioned it in your latest video, so I thought I'd have another look. I think we discussed the torque thing with an extension, anyway, It doesn't matter with a socket end extension only if you extend the length of the handle, then it makes a difference. Check with the physics guys, they know. Just commenting again for the new watchers who might be interested.
I think your video was great and I really appreciate your time for showing how it's done. Getting ready to replace mine. My truck actually blew the intake gasket while I was driving. Smoke poured out and the motor and it just died. Got it home and thought the motor was locked up but pulled the plugs and it blew all the A/F out of the cylinders. Check compression still looking good. Wish me Luck!!!!!!!!!
Currently in the process of doing this on my 98. Your video has been a real help so far. Hope my installation goes as well as yours did. Will let you know in a few days.
I'm going to do this job on my 98 too. I know it's 6yrs later but what kinda problems did the faulty gasket give you?
Leaks, either into the motor or outside back and front
Great videos man! Thanks, they were very helpful since I am the guy who usually breaks clips and rigs things back together :-) It made a job that seemed intimidating at first not only possible but successful.
You do not have to change the torque specs if your adding a socket extension you do if you add length to the wrench
Great video. I used it in place of alldata for reference at home on my personal truck so that i didnnt miss something small and kick a headlight out in frustration later. refreshing to find a video from someone that actually knows what they are doing and what to expect. again, great video, i am now a subscriber.
Great video, I was debating about doing it myself but after i found your videos, I did. They were a great help
Great video. Getting ready to do my 96 K1500. I was at the auto parts store and decided to stop and have them put a pressure gauge on it to try to see the leak. Make a long story short, got 1 mile away from the store and it started pouring out smoke. Motor quit running so I guess they finished blowing the gasket. When I got home I the motor wouldn't turn over so removed plugs and the cylinders were full of A/F. Cranked it for a while to clear out A/f. Apparently it was at the left rear and we couldn't see it. Wish me luck!!!!!!!
Your my go to guy !!! Watched your vids two years ago when I replaced the heads now Im doing the lower intake gasket again I used the same crap ones installed in this video .Purchased the Metal ones this time and made sure i placed plenty of Gasket on the valleys.Distributor has to be the worst part to me
Thank you, lots of older models came with valley gasket seals, they had issue with them and most mechanics would not take the chance re installing do to come backs, therefore they started using silicone as you seen me do, and as you noticed the manufacturer uses silicone as well they started doing the same
thank you!!😎 will tackle this repair on my 97 4x4 tahoe as soon as my back gets stronger. love the tork sequence 👍
My truck is alive thanks to you!!!!!
You show you have knowledge and experience of what your talking about . very good I will recommend your video's to others
Thank you appreciate the feedback, missed you guys glad to be back thanks again
I am new to your channel and if you are still active on this thread could you do a guided video solely on torque wrench proper use and sequence.
One thing I always do,on these is to replace all upper intake gaskets,as well,as it assures no vacuum leaks,and won't have to be done later.
Excellent videos!
Thanks a LOT just got mine done today it was a three day project for me, but now I need to verify the timing, hopefully the dealer won't charge me much for that.
I bet you headed for your favorite drink after all that,Great job!
Getting ready to do mine for the second time at 212,000 on my 97 k1500. First one i put in has failed so im going to try it again. Great informative video will,hope to see more!
Finishing mine up today on a fridged October day. This video helped like crazy thank you! Wish you went over the back together process a little more with all tourqe specs but you can't have everything
Very informative wish there where more wrenches like you doing great videos thx I wrench to but not on gas engines nice to prep yourself with a seasoned person to make sure I don't miss some tricks to ease the process! The again!
Just had mine replaced, a great engine - why did GM have to put inferior gaskets on it? Great video thanks - thumbs up.
Thank you so much. I feel more confident now😃
Nice video , you take your time and show the steps involved in the job. watched the whole video. thinking of tackling my 3500 express in the near future.
you know your stuff,, Thanks again for the help
This video was spot on. I had the worst case scenario my gasket let go and dumped water (antifreeze} into the lifters area. The intake underside and all the rest of the motor looked like runnier baby poo. It took me a few long hours and 3 gallons of kerosene to clean that mess out. I am OCD about stuff like this. And as you said the heater quick disconnect was bad, it broke off when I slipped and fell toward the intake and hit it with my hand. That was a big pain to deal with because I had to drill out and re tap it.I did 3 oil & filters changes before putting in the final oil & filter. The one thing that I am still worried about is the temp is running a higher than it did before. ( about 15-18 degrees higher ) do you have any idea why? I made no changes in that area. I run a 60/40 mix. PS I had two small clamp brackets left over. (LOL)
just finished one of these, told the guy to get a intake manifold... he just wanted the gasket replaced .. so I will be doing this again soon
Just about to start tearing into this myself. Thanks for a great video.
Thank you Sooooo much for this video sir. I have a coolant leak in my 96 Chevy vortex 350 5.7. I thought it was the first intake manifold gasket at the top, never thought to check the lower gasket. I'll try it an see what happens.
How'd it go? I think that is what's wrong with my truck
Sir I'm curious how long did it take you to get the job done?I'm fixing to get started on my 1996 GMC suburban that has the same issue.value cover gasket and manafold gaskets,I have to get it done in one day.Is that enough time?
Good questions, this one I had previously switched out I go through a complete flush process, would recommend doing the same if you decide to switch,
as far as oil pump lining up, one one think it should, however it just seems to be off slightly, its not much barely turn it back just a tad then it will fall in, sometimes it will go in without turning
I replaced my gaskets and they seem to have parts that would cover holes for water flow unlike the one in this video I got at a local auto parts store will this affect the engine in anyway?
I just change the upper and lower gaskets on my 1997 gmc 2500 and everything went smoothly. No more coolant leak... HOWEVER, now the engine stalls out when I give it any gas or it just stalls out by itself.
could I have messed up the distributor install? I did have a bunch of coolant still in the lines and I remember it leaked a bunch when I initially separated the intake. As a result I change the oil again (lots of coolant came out). I can't think of anything else I could have screwed up, but crazier things have happened. please help!
Nice video, Will. Glad to have you back!
Your videos are the best. I appreciated the marking distributor tip that saved a lot of time.
Any tips on how to clean out the threads to replace the Dorman cooling connector #800-401 on the 5.7 L Suburban. Thx again, jeff
Thanks for the Torque values with this video you can't go wrong I going to try the dorman product from ebay comes with new bolts for only 54 00 dollars
Your more than welcome glad i could help, sounds like a good deal dorman is a good product
❤ I'm fixing to tackle this job. You gave me a lot of good advice here. Do you absolutely have to have somebody set the timing with a scanner? If you line everything up back perfect I don't understand why you need to have it checked on a scanner
Great video I have 03 GMC Sonoma 4.3, I smell anti freeze form exhaust and # 5 injector is not firing, ( just started) how long do you think i can run this truck before i start doing some server damage i know this is a tough question but time is not on my side right now I have 2 weeks and drive 500 miles a week before vac and I would like to start this then. How long is this project about i do take my time. hopefully not to brake more stuff, i will change out the spider for the upgrade and new injectors. Thank you for the video RS
Which brand/type of gasket is the best that you recommend?? I heard you say you prefer Metal backing. What Are the benefits of having the metal backing?? Is it more durable? Sorry for the 21 questions... I've been holding off replacing my gaskets for the valve covers and now the intake.. and finally the oil pan. I would really appreciate your help thank you!
Forgot to mention..... it's for my 2000 tahoe limited 5.7 ltr. 2wd OBS.
what bran do you recommend for the gasket & is it recommend to replace the upper gasket as well
a trick : watch movies at flixzone. I've been using it for watching a lot of movies lately.
Victor use the Fel-Pro gasket set MS 98000T I was super impressed they even had 2 orings for the fuel lines. You can get online or from Advanced Auto parts or World-Pac they are super reinforced just did my 5.7 Yes Dexcool is crap. Anyone know the thread size for quick cooling disconnect Dorman 800-401 mine broke off the intake mamifold
Enjoyed the series, keep 'em coming!!
nice video the only thing i did not see is the only thing i needed was reinstalling the distributor
Great video!!!! What a big help this was. When would you recommend replacing the timing chain? 1998 Truck 160k and engine runs great.
Do you have a video showing where all the plugins and grounds are reinstalled? I just replaced my heads and lower manifold gasket on 1997 K1500 5.7. Oh and how the serpentine belt is reinstalled. I know all of this is probably common sense stuff, but I want to make sure I have everything in the right spot. Lol. Thanks for all the help.
Great video. Enough detail almost anyone could do the job but not so much detail it gets boring and lengthy. Curiosity question, do you let your RTV gasket make set (1hr) before final torque and again before starting engine(24hr)?
Question bro. I’m doing a job like your video describes. I’m thinking I don’t need to take the distributor off just the plugs, wdyt?
Awesome video Will! Thanks for the upload... I'm afraid I'm looking at doing this job in the very near future. I have a slight leak at the rear of the motor and can't determine it's exact location. This job makes me think the lower intake gasket is the culprit! Any other suggestions? If you mentioned it before I missed it but, why did you do away with the DexCool? My '97 Suburban has 220k on it and I've only done the injectors & upper intake so far. Kind of wished I would have went back thru all your videos before now and probably done both at the same time since it looks like you have to do the same work! Thanks again for the upload.
Thanks Will for the reply and for the valuable info.
Thanks for the great video. Just tackled the job on my 99 suburban. No more leaks and it runs fine but the cruise control stopped working any tips on what i put together wrong? Thanks again.
Your videos have been very helpful, thank you. I have a 99 1500 4x4 which is the old body style. Have you done the any videos on the spider fuel system??
Nice work Will and I like the little chart popping up showing the sequence for the tightening of the bolts. So on this engine, there are no end gaskets to install like some of the other GM models out there?
Thanks for your help👍🏻
Thanks a lot for your video. Keep up the good work.
Something looks funny here, are those the correct gaskets? or are they revercest ? I don't know if anyone has seen this or mentioned before but I would not think that gasket is supposed to go over top of the water passage to the manifold. Am I missing something?
Looks pretty clean under the hood. How long does the silicone need to set before turning the engine on? Thanks for the video!
Great vid! Will be doing this very soon on my 99 k1500. Cost on parts? Thanks for posting!!!
Very good video. Thanks
thanks robinsonauto. very informative videos and i'm currently working on my truck as we speak. as for coolant, do you recommend using dex cool like the manufacture recommend or go ahead and switch to pristine 50/50. Ive been reading online and found a couple people claimed that dex cool will ruin gaskets over time.. any thought on this subject? thanks in advance.
I forgot to mark the distributor. Balls
You didn't say anything about the scanner hookup I did everything the video said and the light is on saying check carankshaft position sensor
How do you do a great video and say nothing about computer hook up
It was hard to do but I did it and now the cps code came up but my Tahoe runs perfect any help will be appreciated
I have to do the same thing on my 98, while its apart is there any other issues that I could fix while its apart?
so I got everything replaced and connected on the motor and installed the distributor but now it won't fire. I took and marked it before removal and it even points at plug #1 and still nothing. Help?!
lmao
nineright9 what's so funny?
Just did mine the other night and I have no fire to plugs, everything was put back and plugged in perfectly, it seems I have no spark from coil but it was running fine before I started. Did u ever figure out what your issue was?
Just a question. Is there an alternative to the Dexcool IF you completely flush the system?
would you happen to know the part numbers for the two o rings for the fuel line.
thanks.....
can you swap out DEXCOOL from any car just by draining it and refilling it with the green stuff? and when u had to turn the oil-pump counter clockwise a quarter turn, as you pulled it out wouldnt it have turned with the distributor aswell so that all you had to do was stab it back in and it should be lined up for you?
If I want to also replace the fuel injection spider at the same time, can do this work with the intake off the truck than place the whole unit back on?
Yes sir. that's the best way to go. the individual injector legs of the spider only go one way. doing the swap off the truck helps you see it better. just make sure the legs are laying right and not in a bind. trust me! good luck.
Hi, I'm about to have this done and that's why I watched this video. I'm not at all qualified to perform this kind of work, but I like to be able to envision and intellectually understand this process, so thanks. My question is: How long did this take from start to finish, and I mean the actual work time? Also, is it advisable to replace the upper gasket at the same time? I have 103K on my 5.7 vortec now. Thank you and good work.
Not sure if you're going to get a response from Robinson Auto. But here's my two cents worth of a response. YES it's advisable to replace the gaskets on the upper intake at that time. He may have done it and just not included that in the video. The Fel-Pro gasket kit comes with the lower intake and upper intake gaskets and two fuel line gaskets. As far as how long it takes to do the job. It's anywhere between three and five hours depending on how much you really want to clean up and repair or replace. When I did mine the access was simple so I installed a new water pump alternator thermostat EGR valve..... if yours was leaking water the cause is more than likely dex-cool!!! Do not use this type of coolant in your system once you replace the intake manifold gasket. Use an organic alternative coolant. Your new gaskets should be able to withstand the Dex coolant but I still wouldn't advise using it.
WendelltheSongwriter In my humble opinion, I would not replace the upper intake gasket unless it is either leaking or the spider injector is being replaced. I would just check tighten the bolts only with a torque wrench.
Before I get started on such a repair, why was it necessary to remove one valve cover?
ChaplainK because intake makes contact with valve covers when removing. If you remove one them it can removed from from the engine.
You don't use the updated gaskets?
I think I would have removed that heater hose behind the alternator... maybe it was a cable to the alternator, or I would end up lying awake all night worrying if the gaskets were knocked out of place.
Did you not replace the bolts? I heard you have to
A+ , thank you for the video
I have a 1986 4/4 d21 Nissan truck i need to know how I would go about fixing my truck
you put any silicone around those coolant passages? or just the bolts and front n rear china wall?
not sure...i think maybe you put just a tiny bit to hold the gasket in place if you want......but you dont need it at all but only a little in the corners as shown here
On the intake gaskets there is two dowel pins on them that hold them in to the cylinder heads
Awesome video
i have the same engine only mine is 1993. the back ports on my gasket are blocked off. is this normal?
That is good I got it
was it leaking coolant
thumbs up!
awesome thank you, will do
Nice job. Thanks.
No need to go through all that stabbing the distributor. If you catch the gears on the cam all you have to do is turn the engine over till it drops down into the oil pump. Your ignition timing will be fine as long as you have those gears caught on your cam and it'll drop right down when you line up the oil pump drive with the pump.
i only use felpro "problem solver" gaskets on these, nothing else lasts very long.
Good job.
on average how much $$$ does a job like this run?? i think i have the same issue 97 k1500 5.7.
really depends on wat all your goin to do..if just gaskets ..depending if your going to do it or somebody...gasket kit run i think20-40,,probally 300-400..it cost me $1000 in parts and $400 for labor, but i did gaskets, spark plugs, plug wires dist cap and rotor, new radeator, water pump, then your fluids,you will want to change your oil out.,
I need my truck fixed
thank you very helpful just have one question for you if you don't mind messaging me
Decent video, but you are giving out bad info on torquing bolts. You can use any length of extension without it changing the torque applied. The torque is calculated by the lever length, and an extension does nothing to change lever length.
Then you should probably torque down your head bolts with a regular 3/8 drive using the longest extension you can find. Let us know how it goes.
Dont it suck working on cars for real.
man that sucks, go with the metal back gasket i had better luck
Please dont buy the same flimsy manifold gasket,Use the fel-pro Way beefier gasket and will last the life of the engine.
Looks pretty clean under the hood. How long does the silicone need to set before turning the engine on? Thanks for the video!
Thanks a lot for your video. Keep up the good work.
