In this video I show how I messed up doing a somewhat simple job all because I didn't do enough research into how exactly to use gasket maker. I thought I had done enough but didn't quite understand the difference between a metal to metal seal and one that also incorporates solid gaskets. Oh well, it's fixed now and I've certainly learned from this experience and hope you enjoy this video!

It's amazing how much can be learned when mistakes are made and you maintain a positive demeanor.

I love any video that reminds me of my dad who's now gone... Replace the intake gas gets on an Oldsmobile and my old man went golfing. He gave me some advice etc. But like usual I was hoping he'd be over my shoulder. I did the work anyways thought I put the gaskets on pretty well. I started it, said "look dad I fixed it."

Coolant started spewing out a split second later 🤣🤣

"Yeah, now you gotta do it again! I'll show yah what you missed."

Didn't use enough gasket maker to hold the gaskets in place and they shifted when I installed intake.

When I ask my old man why he just didn't do it for me. The first time the right way... he explained. "You learn from making mistakes!"

Miss the hell out of him 😪

The most important part before using liquid gasket is making sure the mating surfaces are prepped correctly. There can't be a single trace of oil. If you wipe the surface with a paper towel and it leaves a black smudge, the surface isn't clean enough. Then of course make sure you lay down a thick enough bead. Typically the service manual will give you an exact measurement of how large the bead should be if you aren't sure

[nilz]

I think the biggest problem here is that the gaskets on the intake are thicker than OEM, which is why you have such a big gap where you apllied the silicon gasket maker. For a normall sized gap/mating surface, the amount of silicone would have definitely been enough. So i think your conclusion at 4:35 is absolutely correct.

If you imagine your intake manifold as a V with a flat bottom. It MUST seal on the V sides against the heads. Since there's no real adjustment on the sides of the V, the manufacturer made clearance on the flat bottom to ensure the sides properly mate with the heads and seal. As you stated, gasket thickness is also a major factor in the bottom gap. This is the one place where a tall thick bead needs to be used. This is completely different than sealing a thermostat housing for example where only two surfaces are involved, there you need to use a thin bead. Otherwise, the sealant will intrude into the internals. Great video!

another tip is to use a finger and smear a thin film of rtv on both clean surfaces before applying the bead of rtv to one side. this ensures the rtv will adhere to both surfaces rather than touch but not bond properly.

Always humbling when can admit you didn't do something right or good enough. And it's nice to learn from a mistake. Appreciate you Jimmy

[davidmckoy]

The same exact thing happened to me a little more than a month ago. Another mistake I made was starting the vehicle too soon to purge the air out of the coolant system. I gave the RTV 48 hours to cure the second time.
I approach this with the same logic as you. Hey you live and you learn. At least you had a positive attitude and made a video for others to learn from.

The first time I installed an intake gasket set was on a Chevy 327 many years ago.
At that time they were still supplying rubber end gaskets in the hasket sets. Using silicone was the new thing back then. I wasn't sure how much to put on, so with all surfaces clean, I set the two gaskets in place then layed the manifold in place to actually see in my mind how large the end gaps were. I'm a visual person so seeing how big the gaps were told me how much silicone was needed.
This time around, you put on exactly the right amount. A tad to much is better than a tad too little.
If there's a little too much squeezing out, its never going to get brittle and "flake" off inside the manifold and clog anything up.

[jonesjones]

With your finger, smear a dab of gasket maker on both mating surfaces really thoroughly. That gets the gasket maker strongly bonded to the surfaces. Then place your bead. Then install the manifold.

This is essentially like putting glue on both mating surfaces, making sure its tightly bonded into the material on both sides. Then placing them together.

This method helps with this area more than most since as you install the manifold, there really isn't much mating presure applied to the gasket maker (since it would rather sqeaze out than crush tighly into place), but since you have already rubbed that thin smear of gasket maker thoroughly onto the block and manifold, once that bead lightly crushes into place, it bonds to those thin areas you rubbed in prior to install. Its 100% bonded tough to both sides the second they touch.

No person starts off out of the starting gate a master/pro/expert at this stuff.
Thank you for sharing your experience and knowledge.

I’m glad you mentioned too much sealant, during the torque sequence of the manifold. When I was a mechanic I discovered so many vehicles with clogged or partially clogged engine oil sump screens with pieces of silicone and other debris from the assembly line.

[campbellpaul]

An intake manifold is one job you need RTV silicone for sure, as a proper vacuum is needed for function and efficiency (just like the heads). I don't know personally which silicone is best, as every mechanic seems to have their favorite that they believe is best. Nice re-do and thanks for showing us, Jimmy!

[nonolabs]

The funny thing about mistakes is that it sticks with you and you remember it forever.
Its been a while since Ive seen a mechanical distributor.
Good job.

[spccarter]

10 years as a mechanic another thing you can do is use studs to set the intake/ keep it from sliding/ hold gasket in place, install a few bolts remove the studs and reinstall factory bolts torque to spec.

[ED-titc]

Im no mechanic and it sucks having to redo a job like this. But at least you're able to do it and learn from your mistake. I sure did! Great job!

[edpowell]

THANKS FOR THE INFORMATION. I always liked using gaskets. One time I had to use form a gasket and was concerned about it as you were. Also, when putting in new spark plugs I use a piece of neoprene hose and put it on the top of the plug and screw it in by hand then I'll use the wrench to tighten it down. I always use the air compressor and blow around the plug then use a shop/vac to suck out any debris before pulling the plug.

[marioacosta-psqp]

This is exactly what just to me. I can’t thank you enough for your suggestions. I’ll be doing my 93 LT1 intake manifold gasket again.
I see my mistakes thanks to your video. Especially the part where u wait before torque sequence and of course liberal amount of gasket sealer.

Thanks for being humble and sharing your learning experience. It gives us DIYer's the confidence and positivity needed to learn!

[MrBowNaxe]

WOW, I was wondering when I watched the first time about that thin layer of sealer... now we both know. Sorry you had to learn that the hard way but, think of how many guys (like me) you saved from having to do it twice! I was excited to see the intake video since I have a slight leak on the front of my manifold. Unfortunately, that job will have to wait until I recover from rotator cuff surgery. Maybe it's a blessing in disguise I got hurt because I was going to do this job on my '99 K2500 Suburban (7.4L) and would have followed your video and ended up in the same boat. It takes a honest person to show their mistakes on YT. Thanks for sharing, can't wait to see what's next.
