I have a small amount of oil coming out of a few of the the intake manifold bolts. What is the correct torque required to tighten the bolts? Any other suggestions?

Car: 1964 Impala SS
Engine: 327 cu.
Transmission: Automatic
Intake Manifold: Edelbrock (not sure about the specs). (See Pic).

Thanks in advance...

Not sure of the exact torque, probably 25# or so......They also should be torqued in 2 or 3 steps in a specific pattern, just like head bolts.....from the centre out to the ends......


If you are leaking oil now, I would think that the gaskets need to be replaced.....you might get lucky just tightening them....maybe not

Torque should be 25# for aluminum 30# for cast and in steps like poncho said.

You need sealant on the intake manifold bolt threads. I usually use oil resistant RTV.

I'll second that and that the bolts need sealant.

Ditto on the sealant. I had that problem even after final assembly with new gaskets on my edelbrock. Oil would pool in the center bolt locations. I removed them and ran a bead of permatex red under the washers on the intake bolts and have had no more problems.
