Hey Folks

Another dumb question.
When you install exhaust manifolds on a 87 Olds 307.......do you use gaskets at the head?......

I was told by a mechanic that it should be metal to metal......no gasket.

That doesnt sound right to me

Any thoughts?

Yep, he's right. Just make sure the surfaces are clean and straight. You are best to coat them with anti seize as well as the bolts.

Thanks Mike
I guess Ill end up taking them off. The heads were off just before I bought it, and they put the manifolds back with exhast gaskets.
Nuts!
Thanks again

Did installing the exhaust manifold without the gasket work? I have an 88 Brougham that I can't get to stop leaking from the drivers side.

I'm afraid the remanufactured head I put on about 3000 miles ago is not true at the manifold; I have burned through three gaskets. I've tried copper spray, red sealant, you name it. Then again, if a gasket isn't required, then no wonder I've burned through them. I put one on the pass side and it doesn't leak.

I'm hoping it doesn't need the gasket; it'd save me a heck of a lot of work! Please let me know; thanks!

Several gasket companies make "dead soft" aluminum or copper manifold gaskets, Around $20-$30. They work wonders on surfaces that are not quite perfect.

Great; I'll give one of these "Dead soft" gaskets a shot. I tried it without an exhaust manifold gasket and she still leaks.

You will be happy that you did.
