Im about to put it in, and I dont know if I should put in it dry or throw some permatex on it.

 

i dunno, my manifolds had a super thin layer of sealant on them. when i put them back on, i didnt reseal them, just put a new gasket on. is this bad?

 

None.

 

Personally, I try to coat all my Mazda OEM "paper" gaskets with a thin coat of RTV.&nbsp This makes taking them off a whole lot easier!&nbsp This thin coats of RTV also help for a better seal.&nbsp Watch out for the lower intake manifold gasket to engine, as these have tiny holes for the air bleed valves into the primary fuel injectors - use too much RTV and it plugs them up!

I've never used a new gasket when doing a R&R on the intake, just from lack of having the parts pon hand. I usually leave the old gasket on whichever half of the intake it's stuck to (which it always is, in my experience), and put either some gasket sealer (Permatex #2), or rtv gasket maker (Permatex Import Grey, forgot part #) on top of the gasket.

I have had the gasket partially seperate from both manifold surfaces once. I just put some rtv on both sides of the gasket. Never had any leak problems.

Sorry, I have a problem comprehending the written word. What is the base intake manifold gasket. Are you possibly referring to the metal one that goes against the *block*. None there for sure. And when I said none in the first post, I mean none but a smear of vaseline as a release agent on the part that will be bolted to the assy. That way when you take it apart later in life, the gasket will remain with the other part and the bolted on part will make a clean seperation. Curious about *base intake manifold gasket*.

 

Assuming he's talking about the lower manifold->block gasket.. You mean, some vaseline on the block side of the gasket?
