Gasket?
 

I have to replace some injectors and have to remove my upper in take manifold now when reinstalling is there a gasket or RTV?

Well I just removed my upper intake plenum and the ports on the lower intake are filthy, any ways to clean them safely?

Since Chris is too busy paying his hermit mechanic outdated car magazines to give you an answer. J/K
Don't bother trying to clean them. They are going to look the same as they do right now after a few 100 miles. If you really want to clean them you can use carb cleaner and spray them which will just make all that crap get on all over your valves or you could pull the lower off and do the same. Personally I would just leave it alone.

Charlie's right. You'd have to pull the lower to do it right and not wreck your bottom end.

Feeling spry?

Take care,
