Anybody replace their intake and exhaust manifold gaskets? I think I have some sort of leak going on there.

I have a 5S-FE engine.

What kind of leak?
Having Lean mixture?
(caused by vac leaks)

yes (on a 1mz)...but they usually don't leak unless they have been removed, as they are metal gaskets (same on a 5sfe I believe)

Actually, it may not be that b/c its an oily substance, but the moist spots are back there behind the engine. I found this out when I was checking out my wheels and I noticed a moist spot on one of those support things on the passenger side positioned behind the engine. However, it didnt have that motor oil smell. It practically had no smell.

BTW, i have replaced my valve cover gasket.
