- In this video demonstration I give a quick over view on how I go about repairing a leaking lower intake manifold on a GMC 5.7 vortec this engine was is used in many models, sorry i dont like Dexcool, hope it helps thanks for watching
Video is 8yrs old but still is a great help. Got the tear down done on my 98 suburban this evening. I’ll put it back together tomorrow evening. Thanks a bunch for the video.
Watched this twice, took notes, started today and now, I'm halfway done. You really made this understandable. I really do appreciate you showing how this is done!!
That's awesome, glad it's helping you along, I appreciate the feed back, Best of luck Hope all goes well

Dude, I just did a head job on my 1999 k1500 Suburban and there was one wiring harness that I couldn't find where it terminated. It was the round plug that goes in the back of the compressor. Five minutes into the video and you showed me where it went.
I appreciate it sir! Hopefully I'll be firing it up tonight.
Super video!
It’s very detailed with fastener/wrench sizes and the component names with great close-up shots with the camera.
Please keep producing these excellent videos.
Thank You!
Thank you for the feedback
I can believe how clean this engine is. No rust or signs of age. Must of been garaged for its entire life. This makes this job so much easier.
I just got finished changing my intake manifold gaskets on my 97 chevy 5.7 Vortec z71.your video helped,thank you. I used the metal Fel-pro intake gaskets.
Best video of removing and installing the distributor for this motor on the Web!! Thank a ton!!!!
Thank you for the compliment and feedback, greatly appreciated
Done a fair amount of shade tree years ago but this video inspired me to go for it. Had job done over the weekend probably saved me $700 to $1k. So handy that you mention what tool and what size. Best of all this repair was on "she who must be obeyed's" vehicle. Now I am the hero!
Thanks for your youtube video it turned this BIG job into a predictable project. It prepared us for all the details and made this job easier. Looking forward to watching more of your videos for our 1996 chevy truck. Thanks for the help from SoCAL.
Thanks for this! Just did this job last weekend and while it took several hours in total, really wasn't that bad. Used the MS98000T's, which have the metal rings in them as you mentioned in the above video. Downside for me was this was an Express van, so had to discharge the AC system due to metal suction pipe. Thanks again!
... excellent video and very relevant to the issue I'm having with my (Canadian production?) 1997 Chevrolet Tahoe 1500 LT SUV w. 5.7L Vortec engine ... intake manifold is very probably leaking coolant (likely at rear, adjacent to cyl.'s 7 and / or 8) into my crankcase and contaminating my engine oil ... truck may have had DEX-COOL in it when I bought it in 2004, however, that has long since been flushed out and re-filled with good ol' green extended life antifreeze / coolant concentrate (I go with a 70/30 mix, a/f to water) from Lordco ... FYI, I once overheated this truck pulling a 3,500 lb. boat & trailer up the Coquihalla Hwy. and had to install a new (plastic tanked!) radiator ... that o/h event may have also compromised the intake manifold gaskets ...
Will, I don't suppose you're located anywhere near Vancouver, Canada? ... if you are, I could easily deliver this SUV to you for said work ... familiarity is everything and I'm convinced you could do this job in your sleep ... Kevin Mc in Tsawwassen, Canada
Thanks, I used this video to do my intake manifold gaskets...great resource. The place I usually take my truck gave me an estimate of $815.00 to do the job.
Thanks a lot for the video. Game me the courage i needed to undertake this job on my 97 Savana. Took a lot longer than my initial estimate yet it was worth it. I think access issues with these vans makes it little tougher. I also had chance to change serpentile belt and the tentioner.
Thanks Will for the reply and I'm sure that the company feels lucky to have you as a technician.
Just wanted to take the time and thank you for making this video, you where spot on in every detail, i have my 1999 Tahoe LT intake manifold removed and both valve covers off, im now cleaning out old muck before the new gaskets go on. I am no mechanic but your video was so flawless i took the leap and im glad i did it wasent really that bad just time consuming labeling everything since im still learning. thanks a bunch man will reply again after i wrap it all up.
Your welcome, I appreciate the feedback. Hope everything worked out for you
Your welcome, I appreciate the feedback. Hope everything worked out for you
worked out great and has been holding strong A+ man
2 years later im doing this all over again on my 2000 escalade ... -_- so glad your video is still up.
Awesome video. Thank you! I'm in the middle of this job now. Wish the EGR tube would have come loose just like yours did. It's being a beast. Soaking with Kroil now.
Nice to have you back Will. Always a pleasure to watch a craftsman in action.
Out of all the other videos out their this I felt was the best, great video. Only bearcat that I found doing this job was getting the distributor to line back up. Other than that its not to bad. Thank you for taking the time to make this video!
Hi Will, first of all, thanks for the great video and instructions! I can't afford to have this job done so I am going to attempt it myself; even though this will be the biggest auto/engine task that I have ever attempted, by far! I NEVER could have even considered doing this job without a great instructional video like this. Anyways, I am curious as to what all I might as well replace - as in valves, sensors, seals, etc. - while I'm elbows deep into the engine?
On the distributor you want to take an automatic center punch and punch mark the manifold and post close together, and you're done with timing. No resetting unless you replace. you'll be within a 1/10 degree
Thanks for a great tutorial on the lower intake gasket R&R, just finished doing the job on my 1999 Suburban, been chasing a llitte bumble\stumble at idle that was only there after it left open loop, lower intake gaskets were collapsing on the tops of the runners.. Felpro to the rescue! SAD SAD list of repairs going after this rough idle, Spider injection, coil, ignition module, crank sensor, plugs wires cap rotor, new distributor, funny thing is with a clean cap it would run smooth for a day, then it would idle rough again, clean the cap and it would go away for a day max then return. No codes, lower intake gaskets for the win!
Was your car misfire when step on gas n jerk stumble ?
iT'S great to know what I'm up against. hoping to buy a '99 tahoe with an apparent intake gasket leak. Thanks for makin' the video! CHEERS!
Use the felpro "permaseal" intake gasket kit to never have another leak. The factory astic intake gasket is junk and prone to failure. The felpro is a rubber overlay on a steel gasket
Thank you, i could never abandon you guys worked to hard to form this friendship means to much to me now :)
I appreciate it glad to be back thanks again
Awesome videos Will, keep em coming. I like ur explanations how u show the fix from start to finish
Thank you for the feedback and compliment, I will need to see if I can find a name on it, had that one for years needs a new lens sleeve its all scratched up, I got that light from a rebuild center that closed up, at the time i had two spare lenses, and a box of bulbs i still have some bulbs lol would like to find out as well so i can buy the lenses its been great for i would say six years or more
Very detailed video thank you from California🇵🇭
Thanks, wasn't as bad as I thought it would be. Got hung up on cleaning though so it took a while longer. Back up and running.
It really is to be honest i enjoy it when new equipment comes in, been with this company going on ten years so when new challenges arrive its nice to get involved brakes the norm,
I do, not so much as far as the initial installation however i do work hand and hand along with the electricians even though its not my title, that stems back to my earlier yrs when i was the only tech on the off shift, had to learn it all took some classes however main knowledge has been formed hands on.
That was a almost a great. Video. 8.5. Some people like me yould like to see the things that you thoubht would bore but the vaccume lines is why i needed to see how the were run from passenger side to driver side. I did learn alot but u need to assume the homeowner knows nothing and needs to see every move u make its very intimidating for uour basic homeowner to tackle a job like that. But for a shade tree mechanic. Would probably be perfect. Keep the videos coming
You are an excellent mechanic. Thank you for doing this. Couldn't have watched a better video.
I watched your video and wanted to say thank you it was very helpful. I replaced my intake gaskets yesterday on my 98 no more leak . But I'm still chasing a slight misfire at idle
You said you hooked it up to computer to "further adjust the distributor". I was on the road dead, towed into a small shop, received my second distributor in 20,000 miles...wife drove it home with a new noticeable miss. I have been chasing this miss...,to no avail and here because the valve is tapping and thought maybe the annoying miss is that or possibly an internal intake leak. Thoughts?
@@samk1584 probably need a new gm dis cap , shorting out between 3 and four.
Don't buy a cheap cap
Awesome video really really appreciate it. Shout out to you now I can do this job I'm a marine vet that's not working and so this was extremely helpful and I appreciate your patience and making this video have a great week
Matt
Right on. Followed this through and first crank started right up. Thanks brother.
Nice job. EGR has a crack in the base flange. I noticed it while you were talking about the heater hose on the water pump. I have one of these trucks and it just running like junk right now. I think the spider is failing.
Hey thanks for this video only reason I felt I could do this job. everything went well only had a ft lb torq wrench small amount it did was 10lb so I hand tighten the intak then a little tighter then to the final torq. when I turned my tuck off after warming it up coolent came from somewhere right above the lower radiator hose where it connects to the engine. I don't believe it was the lower hose but something above it
Did the intalke leak water into the engine? I have one that did that. Having a hell of a time getting to run right now. I think there is some water trapped in lifters. I was thinking about draining oil, unplugging coil wire to HEI distributor, and cranking engine over a little while with no oil and no heat to ignition. My intentions - purge lifters of any water that got in there. Do you think this could help with my problem? Thanks.
thank u for video..im in middle of ripping mine apart..i think its got a gasket leak causeing high idle start up..and i can drive down the street with no foot on gas..
Ur video is very detailed. I'm currently replacing the intake gaskets on my 5.7 vortec silverado. I was curious tho, does the distributor HAVE to be removed to get the intake out? and what tool would be perfect to get the lower fuel lines disconnected, cuz a regular wrench wont fit. thanks in advance
Excellent video. I will take issue with the Dexcool thing, though. I've replaced hundreds (if not thousands) of TBI 5.7/5.0 intake gaskets that predate dex coolant. It is my opinion that the problem is more with the crappy nylon backed gaskets rather than the coolant (not to mention lack of maintenance by their owners). Every 5.7 I've fixed with the second design metal backed gasket had no issues even with Dex. Super crappy design either way, with only 4 bolts holding the lower intake on.
Any advice on how to remove a frozen EGR tube from the intake manifold? I cannot budge the thing. It's the only piece I'm having issues with. Very frustrating...
next inline is the drop machine now this has many options, however lets say we have a 2000 count bar in place ever every so many seconds it deposits 2000 drops on a belt that then goes through a cooling tunnel, when discharge then goes through all the packaging equipment, from the box erector, bag inserter, filling station, box sealer, running at pretty high speeds, i have been manly setting up the packaging equipment, pretty much where all the mechanical and logic become one hope that helps
Good vid ! Thanks for uploading. I'm going to drain radiator 1st to get top hose out of the way. Just one smart azz remark: You have successfully renamed mounting bolts to be "retainers"...lol.
@Brandon S : You can call them securement device if you want to. As long as parts stores still know what a nut and bolt are that's what I'll call them as I have since the early 60's.
I have a 99 Yukon and what are the symptoms of a bad intake gasket?
Please tell me what was the reason you did all of this bedside replacing the gaskets because it was leaking... What was happening with the engine
At 5:40, you have 'another wire here', in a clip that you release. What does it go to and how important is it?
So it's NOT required to remove the actual distributor? Just the cap and rotor?
Great info! I'm pairing your videos and some other people's as well for my own project. Thanks for all the great information!
was nicely done , I liked the fast forwarding showing the process. Believe I can do it now!
so my main experience with PLC's is using to help trouble shoot along with schematics its nice to bring up logic and see real fast whats stopping what, oh hey this down stream prox sensor thinks it is made stopping the line, failed high, things like that most times i can resolve without however its nice to know, also work along with the programmers during setup, or if a card fails replace it, where i do get into programming is VFD's and such,
Awesome video! Great to see you again! Learned so much from your videos.
Thanks for pointing out the location of the hardware on the AC/PS brackets. I was missing that bottom bolt, I missed it because it was covered in 17 years/200k worth of oil and road grime
Great video helped me out alot. THANKS MAN
Great video... I been thinking of changing out mine on a 1997 chevy Z71.
Mine failed where he first started pullingoff the martierial the day after i bought my truck from a friend. He helped me fix it and its been. Fine since. Took a few days spent more time drinking beer cause we had just got back from afghanistan
+CB1942EO Going through it now Brother, I'm on Day 2 LOL can't put down the Budweiser LOL.
Understandable each to their own, like I mentioned just my opinion, the hardest part to swallow is lol I shouldn't say swallow and antifreeze in the same sentence, seeing all the issues first hand correlating to complaints filed, lawsuits directed at dexcool more than any other
(search it will blow your mind) I chose not to take any more chances yrs ago and stopped recommending, however im not no chemistry expert and still use what the customers prefers, wouldn't use it in my truck just saying
Great info any advise on after intake installed engine start to knock when 350 chevy warms up
Priorities always come first. Thanks for the video. Take care man
Thank you for the compliments, that's awesome and what keeps me posting thanks agian
Thank you, yes I prefer the improved metal backed gasket, however, lots of times I let the owner pick up parts in a attempt to save me time and them money, in this case you will see he purchased the other style however its fine will outlast the rest, at this point in the trucks life I wasn't to concerned lol however yes metal backed when I have a choice
I seem to have broken the part your screw driver is pointing at/touching at 10:58/59. What is the name so I can get to finding one. Thx
were the gaskets leaking coolant internally or externally?
Long shot but I have a coolant leak on my 98 gmc sierra. Can’t really see where it’s coming from but when the truck is running leak is first visible in the area where the front part of egr tube is connected it runs like right underneath it (fitting and tube are dry so the leak isn’t there) once I turn the engine off the coolant sort of sits there and then little section to between the fitting connection and the manifold. Is like a little cave. Would you have an idea of maybe what components to look for that can be leaking around the area.
T.i.A
If I was to replace both the lower and upper intake manifold gaskets would it be safe to assume I follow this video first up until I remove the lower intake assembly (which includes the upper intake?). Then once the lower assembly is removed I then take the upper intake off of that whole unit to replace that gasket and then I proceed to re-install the whole intake? I've seen separate videos's on how to do just the upper gasket but none that cover both. I would think most people change upper and lower at the same time?
appreciate any guidance on this- I'm pretty sure I'm blowing antifreeze from both top and bottom......
HAS ANYONE SOLVED THE PROBLEM WHERE AFTER YOU DO THIS IT WONT TURN OVER AT ALL?? Please help!
Thank you, missed you guys as well
Thank you for the compliment, thanks for swinging by and watching I appreciate the feedback thanks again
GOOD CONFIRMATION FOR THE LOWER INTAKE REMOVAL
Are the steps basically the same for a NON-VORTEX 1995 chevrolet g20 van 350 5.7L? Could I just replace the lower intake manifold gasket or would I need to replace both upper and lower intake manifold gaskets, because you said everything breaks easily??? thanks!!
welcome back i missed your informative videos
Great video Sir. 👍
Thanks 👍
Did you have coolant in your oil when your intake gasket failed?
working on the same engine do you have to adjust the rocker arms in the firing order and prime the engine before starting up?
The engine should be primed three to four times to get any air out of the fuel lines.
Thank you, trying to be myself these days, i work for the largest cocoa processor and ingredient chocolate supplier in North America, yea yea here comes the willy wonka jokes lol
from the cocoa been to finished product we do it all, mainly bulk supply
the new line is what they call a drop line, once the chocolate process is done, we take and run it through what they call a temper machine, tempering chocolate is an actual science check it out some time, melts in your mouth not in your hands
Where and maker for your work light?? I like it..
I didn't put it in there but minus the 1998 K 1500 5.7 l Chevy Silverado pickup half ton so thank you sir
should i dropped the oil pan on this 350 motor 1500 after intake installed i have changed the oil 2times already this was a perfect running truck what could the guy installed this intake done wrong to make this engine start knocking any advise would helpful also the timing was 20 degree out of timing
What you are holding at 6:47 is the pressure switch to the AC. I had a gm dealership work on a different issue and when he gave me my tahoe back, it was broken off, schrader valve and all. the metal was torn and he denied doing anything. It appears I'd need to have a new port welded in as opposed to buying a whole new ac unit. What are your suggestions? I have been without AC since, and I'm in 120 degree+ in AZ
I have the same exact issues right now coolant was gushing out after I had already replaced the water pump, thermostat, and radiator cap. What is the part # for that gasket, please?
What kind of camera setup do you use . Do you have it on a camera tripod. Nice info your very clear in easy ti understand
Good job Will. Is there a particular brand of intake gasket that you prefer on a job like this? Thanks for posting.
need help got a 2000 limited tahoe makes a noise only when in park took to 2 different mechanics 1 said its THE flexplate another said tourqe converter but had both checked and both r good any ideas of where it can be coming from
New subscriber just because you pay attention to details. Thanks I appreciateyou Charles
Great informative video. I was able to save myself about $650 by doing this job myself.
Great video, about to do this for the first time because my 98 is leaking down the back of the engine. I was wondering why the valve cover comes off? Is that just to get started on prying the intake loose?
Where does the other end of that vacuum climate control line go. Not from where you disconnected it, but the other end that is still connected.
Hi Will and welcome back. Nice job and you seem to be more relaxed in this video. What kind of process does the plant that you work at have? Good to hear that your company is doing some expanding instead of closing the doors like a lot of them do.
what happen to the rebuild ?
I know where you are coming from. Plus, Dexcool is a bit more expensive than green coolant. A lot of my time spent in the business was at various GM dealers from 1998 to 2008, so it was pretty important to them to make sure things stayed 100% factory. Another secret motivation for using Dex in my personal vehicles is that I've got quite a stockpile of Dex (and a lot of other GM branded fluids) from the last job I left in the form of an unauthorized severance package
:) lol thank you feels good to be back i appreciate that
I remember doing one of these last year. Good video.
What’s that hole in the center of the intake near the firewall at back what plugs there has a orange gasket in it to it’s the only 1 inch hole in center of intake at back in front of distributor
I have this same exact vehicle and have fluid leaking somewhere from the back towards the top of engine. Leaks straight down on the drivers side right where the engine meets the transmission. Could this be the lower intake manifold gasket as shown in this video? Usually only leaks bad when very cold but stops once she's all warmed up. I need to see if I can get a mirror or camera back there but if not this what else can it be leaking fluid back there? I've been stopping the leak with various stop leak products over the past 5 years now with each repair lasting about 1 year / 10k miles. Truck is on its last legs and want to try to squeeze just a few more months out of it if possible.....
Just my piece of advice always fix the prob soon as possible no temp fix, especially stop leak ur asking for ur radiator and heater core to clog up im highly surprised they haven't. It is a guarentee thats your intake gasket the original ones are junk and made from plastic when bad you will have single or multiple missfire, coolant leaks from front or rear intake area and possible coolant in oil
I have a question about the signs and symptoms. I was wanting to know if it just all of a sudden happen and if at the time it puts water into the oil like a head gasket would ?? If so how do you check the heads to find out if it blew the head gaskets also??>? My 96 suburban was running good and I dropped off a girl i know at her house and when I was going home all of a sudden it started puffing white smoke out the tail pipe and it started running rough and then died. My suburban had only quit running on me one time before and that was when the ignition module went out. Please someone answer me please.
you blew a head gasket or possible crack on head itself. I know first hand this happened to me as well.
i ask, because, I can see the clip on my 96 tahoe 5.7l, but the wires are completely missing altogether....yikes? or no sweat? expected problems I should be seeing if missing? a dishonest mechanic's cheap workaround? I need your help or advise...signed, a confused gramma in AZ with a downed tahoe :(
I would recommend look for the upgraded gasket that Have Metal in it avoid the plastic gasket those are known to fail

Good video!! How many hours of labor would you charge for this job?
Hey that sounds like some pretty interesting equipment. Do you get a chance to work with the PLC's and/or do any of the programming, electrical hardware design? When I worked in maintenance on industrial equipment, I always just enjoyed figuring out how those machines worked. To me, it's all very interesting.
I replaced the quick disconnect with a straight valve and usually find the bolts that hold down the intake are out of torque spec I have had luck just retighten
