gasket sealer on new intake?

[hatchsub]

Hey all,

Im going home at the end of the week and i have plans to work on my suby by swapping intakes and carbs (going from one barrel carter-weber to hitachi two barrel). Ive been told that its ok to use the permetex high temp copper gasket sealer on the intake gaskets...but should i also use it on the carb gaskets to guarantee a good seal and what about the EGR valve gasket? Should i only use the sealer on the intake gaskets and and just install the others dry but make sure the surface is very clean? Just trying to make sure i do it right the first time. Thanks guys.

I always install carb gaskets dry. Same for EGR.

It appears to be a matter of personal preference. So, personally, I've had good luck using the Spray-on copper stuff on both the manifold gaskets and the carb gaskets. Leave the EGR gasket dry though. Anything you put on there will just burn off from the heat.

Ok thanks guys. One other question sorta on the same topic...should i worry about getting the bolts out for the intake without ruining the heads? I figure since the bolts appear to be aluminum and i know the heads are that i shouldn't have a problem. I just have to be careful how far i torque them down when i put on the new intake.

The bolts are steel, but you should be fine - they shouldn't be very tight.

 

Always use a torque wrench when reassemblig stuff like that.

Ok thanks. I was just planning on borrowing a Torque wrench from my local shop..the've known me for awhile and let me borrow lifts and tool here and there.
