Hi, am currently doing this job. I am using chiltions full size truck manual, 1988-98. Manual # 28624. This is a pretty good book. Intake manifold section 3-22. What it doesn't tell you is: you must push the csfi through the upper intake manifold. I would be happy to help you in more detail: Call my cell phone anytime. 760-792-2449. It's much easier that way. Simple when ya understand the trick! Ciao! Scott.
Remove the intake manifold retaining bolts from your 1996 Chevy Astro Van. Remove the manifold gasket and clean the surface. Reverse the process to install the new intake manifold gasket.
there is no lower intake gasket, only a front and rear gasket
The labor charge to replace and intake manifold gasket, on a 1999 Chevrolet Tahoe, is approximately $180. It takes approximately 2 1/2 hours to replace the gasket.
Remove everything on top of the intake (hoses, fuel rails, linkages.) Unbolt the manifold and remove it. Clean the old gasket off and replace it. Reinstall all parts removed to get to the gasket.
The gasket set is $55.00 The labor is $250.00
Assuming this is a 4.3L engine, the upper intake manifold gasket would be between the upper intake manifold and the lower intake manifold.
well so far it cost me $700.00
is their a web site, that will provide me with the a print out for the intstalling of a intake manifold gasket for a 2003 chevy aenture.
If you are sure that it did not freeze and crack the block, Then the intake manifold gasket is leaking. That is a common problem with the vortec Chevy engines. You need to replace the gasket with a factory Chevy gasket from the dealer.
It should take about an hour to change the intake manifold gasket. This part can be replaced by taking off the intake manifold cover, cleaning the old gasket off and sealing a new gasket in the space and tightening the bolts. When other things are in the way, like the alternator, it will take longer.
You either need a head gasket or intake gasket.
