I too have a Venture with a 4.3L that has a leaking intake manifold gasket. I have been told that the repairs to my 1999 Venture would be around $500 - $600 for a "shop" to fix this for me.
I'm going to do this myself but am wondering what to torque the intake manifold to when I put it back together.
Can anyone answer this question and give me any advice that they have experieced when they did this job?

Thanks!

Are you sure about the engine size, my 99 has a 3.4. we had the intake gasket done at about 36000, the dealer did it, and the price would have been aroun 1000,00. I got GM to cover it. It is a lot of work to do this, good luck.

99 Venture comes with a 3.4 v6..
Usual price here at the dealer runs just under 700.00
At my shop it would run you about 350.00

Hello,
I going to replace my parents intake manifold gaskets. I was wondering what brand of gasket is best to use.

I did the intake man gasket myself with help from a friend in about 6 hours. That was 4 weeks ago. Today I changed the plugs and wires. Advice- change plugs and wires when doing gaskets. The rear plugs are a pain and would have been easy with the top of the engine off.

buy Fel-pro gaskets, part number ms90565, should run around $50. Get yourself a Haynes manual, as it will give you the proper torque sequence, as well as the torque value. If you are mechanically inclined, it's not that hard a job, just a little time consuming.
