How to Replace an Exhaust Manifold Gasket - Chevy 350

[@HoldFast-un2fc]

Had to go thru a lot of videos just to finally tell me which side of the gasket goes toward the manifold. Great video!

[@Geoduck.]

Thank you! This helped me view under the passenger side exhaust manifold heat shield. I now know how to remove it 1985 C10 SBC. Another tip for exhaust manifold bolts Kroil spray. Let sit a few hours then GENTLY smack the bolts a few times with a large hammer. Gently is key then spray again let wait overnight.

where can I find that exhaust recirculating valve round gasket? can't find the right one in google, mine looks exactly the same as yours

[@woecp]

Did you have to get under the car to take the passenger side down pipe bolts off ?

[@mariorowland8342]

Great video, I thought it was my lifters or cracked flexplate, saved me a lot of time and money on my 86 trans am, thanks again.

[@MechanicLife]

You bet Mario!

[@whydoikeepgettincut]

Thanks for the video. The cover pic actually gave me the answer I was after. Got the same odd ball exhaust gasket with an extra tab for a 4.3 and couldnt see where it went in my astro van. Passenger side cylinder 6 for anyone else lookin for the same answer

[@Redlinesixtynine]

Anyone know how tight to torque the flange nuts onto the studs? These have the heavy spring between the nut and the flange, so just tighten them right down? thanks.

[@crystrezerex2life]

Which way does the gasket go if it's all metallic? Flat side or rippled side towards the cylinder head?

[@nathanharris8624]

Flat side

[@tonycugudda250]

What is the part number & brand to the gasket that goes between exhaust manifold and EFE Valve?

[@MechanicLife]

I cant remember sorry! I got the parts at Autozone however. They are on a 350 Crate motor. Gaskets were Felpro

[@Kingofspokes]

my manifolds were warped so I got em machined but I'm still having trouble getting em to seal up against the block, do u think doubling the gaskets would work?

[@MechanicLife]

No. When you compress them together they will have the tenancy to split or smoosh each other out of the way of the other one creating leaks. Most of the time you can find a thicker gasket. Are you using any gasket maker with your gasket? Permatex makes some for exhaust manifolds called ultra copper. That would also be a solution. Did you throw a straight edge on the manifold face to check how well the machining was done on them by chance?

[@Kingofspokes]

What do u think I should do then?

[@MechanicLife]

1.) Put a straight edge on your manifolds and confirm they machined them down correctly. Your straight edge should lay flat against all of the ports on the manifold. Also check how even the block is with a straight edge. Check minute 8:04 of my other video. kzbin.info/www/bejne/pX23qHiJiNmlarc&lc=z23asf4acwbivl0rv04t1aokgb4a01zpzcplk0uwmh1crk0h00410 2.) If that checks out, I would hit up an auto parts store and see if they make a thicker gasket first/check out Summit Racing or Jegs for thicker gaskets. You can find extra thick ones. Also make sure you are using new studs. The old ones will stretch. Make sure you are using the right patter torquing down the bolts to spec as well. I have over tightened a few times causing leaks that way;) 2.)Try Permatex with your gasket. Make sure you let it cure for at least 24 hours before you start your motor. 3.) Worst case. Buy new manifolds. What engine are you working on?

[@omartinoco9930]

If your car has a one-piece gasket unlike this truck then you need to check the surface against a straight edge and shine a light behind it. You should just try to file it yourself if the metal shop ground down uneven surfaces..

[@ReyReyDewit]

How much did machining the manifold run you?

[@nandoflores8261]

Which gasket is this I have 1995 would like those

[@Rico454_]

What gaskets did you use are you able to send the link I keep getting diffrent ones from the parts store and they are all wrong

[@MechanicLife]

I bought them from Autozone. They were a Felpro brand.

[@vincentmosqueda8166]

How much does it cost for this repair

[@MechanicLife]

One side doing it myself just the parts were 160. I already had the welder and tools.

[@robertpeters1497]

i have this for my monte carloi it start at cold start then leaves put when at wob or 60 it leave around 80kph , my bolt snapped off

[@countrylivingguy5172]

What is the part number on the donut gasket?

[@MechanicLife]

I cant remember!! I got it at Autozone. 1984 GMC Jimmy 4WD 350

[@James-fr9sq]

Won't rtv just burn off?

[@mikepoint4717]

I just bought a old school 350 today and apparently the manifolds you have are hard to come by and getting pricy .

[@MechanicLife]

They are getting tougher to find for sure!

[@reyzapata9375]

Great Video you did. But, if you’re using Fel - Pro gaskets there’s no need to use RVT gaskets glue. Fel-Pro gaskets automatically sealed itself.

[@jessesalinas1220]

Does the down pipe of the exhaust manifold have a gasket ?

[@lindseysteele1436]

What years us this it looks like 305 heads to me

[@MechanicLife]

This is off a 350 crate motor.

[@william2glaser227]

what do you use for editing?

[@montanamade1114]

I used windows media player, but have since switched to Camtasia. Its just a easy to use, but much more robust.

[@spookplays6316]

Helped me doing this to my 1969 caprice👌🏽 thanks

[@mattmgarza]

My gaskets are metallic on both sides....hmm

[@MechanicLife]

If there is a smooth, metallic side and a composite side, the smooth metallic side should be installed facing out, meaning toward the exhaust manifold.

[@mrbrocephus3849]

Good video I have a 75 chevy caprice classic looking forward to doing this 👍

[@vennt79]

Thank you

[@hosseinsoltani7739]

Good job

[@20alphabet]

Why use gaskets at all? ...smh
