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!!
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.
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!
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
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.
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
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!
... 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 ...

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!
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 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!
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.
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.
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.
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
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.
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
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.
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?
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.
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
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,
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.
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..
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
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
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
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.
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?
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
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
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
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
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
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...
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!
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.
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
On this particular intake gasket, there is a set of intake gaskets that are "bullet proof" it contains a metal sheetshim in between the intakes. Should last longer. Vs the OEM intake gasket. For Chevy, GMC.
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
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
i bought a 10 foot section of clear tubing from hardware store and siphon out radiator so i can reuse the fluid when its good. this way i don't have to remove hoses.
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
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?
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......
Ive got 505,000km on my '98 Sierra (310,000mi) As the 2nd owner I know its never had the dreaded intake gasket problem. I wonder, if its because the DexCool was flushed in my truck regularly every 24 months? (the previous owner followed the Heavy Service schedule in the manual) I know theres a majority of DexCool haters out there but theyre fixing engines that have probably never had a coolant flush done in the vehicles lifetime, and they dont know the history of whats been dumped in the rad.
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
Also human interfaces for example the said packaging equipment, timers and moving parts, we run different box sizes that require changes in the program, example i would hate to put 50lbs in a 25lb box or a 25lbs box fills faster the transfer time is faster than on a 50lb if that timer isnt changed you may start transferring the box out of position before its full oops, during the initial set up i created different recipes for each box ran, therefor operator selects box size and off we go
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!!
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’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
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.
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?
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
