buy a haynes book for your model car at any auto parts place.they are about 20.00 dollars, the book is based on a complete tear down of vehicle,I just did mine I followed the book and had no problems,But where the fuel goes in rail do not loose rubber "O" ring,or it will spray out fuel!! I made this mistake and had to tear engine down again to replace "O" ring!!! good-luck! o-ring is in the line where fuel enters rail..
Yes, you must install a new intake manifold gasket.
You will have to remove the intake manifold and install a new intake gasket. You have no choice.
Remove the intake manifold retaining bolts on your 2003 Chevrolet Malibu. The manifold will come off. Remove the manifold gasket and clean the surface. Put the new manifold gasket on and reverse the process.
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.
It is between $65-$85 for the gaskets.
if its a 3.1, the possibility is the intake manifold gasket!!
Intake manifold gasket
The head gasket on a 1999 Chevy Malibu is replaced by removing the coolant, intake manifold, and retaining bolts. The cylinder head can then be removed, the gasket replaced, and everything reassembled.
I'm sorry but i actually have a 99 Malibu and they do have a intake manifold gasket which are commonly mistaken for a head gasket when it blows. Mailbu's 97 to 2000 are bad for them blowing. it is located on top of the engine. it's still very expensive **tamnesha Some Chevy engines of that period didn't have a gasket; just a thin film of sealant.
The intake gasket is the gasket that conncects from your air filter into your intake manifold
Between the intake manifold and the cylinder head.
