Title: Intake Manifold Gasket Choice
Post by: CarsandDrums68 on October 12, 2017, 09:14:26 AM
Hello gentlemen,

I had a failed intake manifold gasket on my 1968 DeVille Convertible which caused a vacuum leak, so I'm going to take off the manifold, replace the gasket, and torque it plenty of times. My question is who makes a better intake manifold gasket, Fel-Pro, or Victor Reinz? I know they are both pretty good names but is there any benefits to one or the other. It is an aluminum valley pan and i will be using a high tack gasket sealer.

Thanks,
Al

"and torque it plenty of times"

I'm not sure that's a good plan.  Depending on the final torque spec you might want to torque the bolts in stages rather than to the final number all at once.  eg. If you the spec says 30 ft/lbs. make your first pass at 15, then go over them again at 30.  If the number is high like 100 ft/lbs I'd say torque the bolts in 3 stages, 30, 65, 100. Obviously, following the pattern in the service manual.

Exactly, I didn't mean all at once, i meant in increments as you said, which is a great plan. I believe they are supposed to be 60 foot pounds. When I found the problem some of the bolts were loose, so I want to make sure I torque it once, and then maybe again after a week or so of running it.
