INTAKE GASKET MAIN PAGE, PLEASE POST Q'S&A'S HERE!

[91celicaFB]

Hey, So much information about the head/intake manifold gaskets here but they are all scattered. Please feel free to copy and paste useful information here. Let this be the main page for the gasket problems.


Okay, first off, I have a question. I am going to replace the intake manifold gasket on my 1998 Chevy Venture 3.4 tomorrow.
I know my way around things but this one looks pretty complicated.
Has anyone done it before and if so, what are the steps. Everything looks so crammed, I'm not sure what to take out first.
Please help me and others with the notorious gasket problems!
Much appriciated if replied to before wednesday, (im trying to get it done before the holiday's, parts stores are closed!!)
Thanks!

Did it myself. Followed the Haines Manual directions pretty much verbatum. My advice.
Have oil and filter for an oil change when finished. Coolant too.
Change the spark plugs with the manifolds off. Very easy job at that time.
Label ALL hoses and wires. I almost forgot one.

Thanks for the advice, Im trying to locate the damn manual but its no-where to be found. At first, i wasnt sure if it even mentioned how to do this. But thanks to you, i know that it has the information i need.
My search for the book is now accelerated as i am trying to finish this today!
Thanks
PS. any special tools required?

Hey,
I started working on it today after getting the manual. The manual seems to leave off important steps, like how to remove the upper manifold. I couldnt get it off! Now, im unsure if it was the bolt under the egr or some kinda sensor infront of the distributor.
Please help, i had to put everything back together cuz i couldnt get the upper manifold off.
*do i have to pull the engine foward??
thanks!

I just wanted to let the forum know that the GM dealership has covered half of the expense. I have only owned the van for 3 months and i bought it at a non gm dealership. My total cost was 380 canadian taxes included.

I hope this is helpfull for someone

I lived in Ottawa and the GM dealership charge me CAD 1,200 to fix my intake manifold gasket!!! Even you pay half (i.e., CAD 380), the dealer charged the total cost for only CAD 760??? That is a big different between prices

Since this looks to be a helpful thread, I'll pin it so it will be easy to find.

Please keep the questions and replies only to the actual repair procedure.
Please read all the posts here to see if someone has already asked the question before. Some vehicles (even though they are the same body style) have different procedures and tricks to getting the job done...so please post the year and engine size so you get the correct information

If it's not too much trouble, could you email me the instructions or post them somewhere for download. I have a Olds Siloutte with the same leaks. The instructions should still apply. Thanks.

Ok I'll post these instructions....I'm doing this off the top of my head, but basically anything you see in the way of getting the lower intake off must be removed or moved..
you know the basics..drain the coolant, disconnect the negative battery cable
1. air duct
2. throttle cables and mounting bracket
3. coil assembly
4. T/B hoses
5. egr valve
6. upper intake
7. alternator and bracket
8. fuel rail
9. P/S pump
10. studs for coil assembly
11. heater pipe
12. valve covers
13. lower intake

you will need to loosen the rockers and remove the pushrods
This is important! keep the pushrods in order..the intake and exhaust are different lengths and if installed in the wrong position will cause immediate engine damage when the engine is started!
clean everything up and install new gaskets
reinstall the manifold and torque to specs
reinstall everything.
