On the 3.1L engine you have to remove the push rods to replace the intake manifold gasket. It is possible that you didn't tighten down one rocker arm, or you have it mis-aligned.

I have a pontiac and i keep blowing head gasket on number one cylinder. I have installed new heads and gasket lasted about five years. I was wondering what the correct head bolt torque is for a 1995...


cylinder head bolts, step one;33 ft. lbs, second step rotate an additional 90-degrees (1/4 turn). do not put any oil or sealant on gasket. the gasket should seal itself if torqued properly.

I need to know what the torque spec is for a auto trans. pan gasket on a 2002 Pontiac Grand Prix?


It is actually 10 ft lbs. This is something that you want to tighten to exact specs.


Hope this helps!

Need head bolt,intake upper and lower and rocker arm torque lbs.


Head bolts--------- 22 ft lbs.
Intake upper------ 18 ft lbs.
Intake lower------- 10 ft lbs. Tighten vertical bolts first, the diagonal bolts, failure to do this will result in an oil leak.
As far as the rocker arm bolts, they have to be adjusted with the valves closed, tighten down just enough to turn the push rods with your fingers with slight tension.
This is out of a Technical Specifications Manual.
