Manifold Gasket

[Lyle A]

My Intake Manifold gasket leaks a little oil. Anyone know what the normal time and difficulty is involved in repairing this problem? Also, any special tools involved?

Very common problem w/lt-'s. I would say about 2 hrs. depending on how mechanically inclined you are and how long it takes to remove the old gasket materail.

two houes would be a VERY fast install. to do it right you need to let it sit over night to let the silicone setup correctly ;)

OK,even if it took me four and I let it sit all night, Are there any special tools needed? Like to remove the fuel rails?:thinking: The shop I would use wants like 400 bucks to do it. I can do it myself but don't have any experience with LT1's. I have a Gm manual. I guess thats a good place to start.:duh:

Well for $400 i would get it done. Just make sure they let it sit over night with out starting it.

Other wise special tools will be the fuel disconnectors. you will need valve cover gaskets also. they are re-usable but being this old I would replace them ;) It is fairly straight forward. be very carefull with the bellows. it helps to have a second person when sitting the manifold on.

definately get another person to help you.. you dont want to screw up trying to do to much by yourself..

You have a tendency to get rather quick at it after taking the same things off over and over again. I agree on letting the silicone sitting up and curing completely. I know it would take longer if a lot of work is involved in removing the old gasket material.

Yeah it can be faster but first tiem will take time.

Then again we yanked my motor tore it down put it back together with new bearings,cam,lifters,oil pump drive,new seals and gaskets then reinstalled it in less then 14 hours ;) we would of had it running the same day we drove it in but I had to wait on new heater hoses from Flint Mich. ;) I always pull the motor out of the top and pull the trans at the same time ;) So this included removing and re-installing every thing from the A/C condenser to the drive shaft :D

I must admit I have done it faster on Winston West cars ;)

I pulled mine from the top also. I wish I had a 2 post lift so I could have pull it out from the bottom. By the way, I think $400 is WAY TOO HIGH!!!!!!! Shops around hear do it for $200-220. That's labor only. The gaskets run about $16.

About 4 years ago I was charged like $500:rolleyes: Then when I did my Hot Cam I then realized how frigg'n easy of a repair it would have been for me to do it.:crying2: :crying2: Oh well that was when I had tons of $$$ falling out of my pockets... My tip for you would be to make sure you cover up the lifter valley & make sure you clean your surfaces real good. I was pretty generous on the RTV too. I am not looking forward to trying to pry it off now when I do the heads....:bash:
