Thread: Oil on intake; hard to start, backfire....

Tweet

ussually ones you get anything leaking through an intake gasket, retorqueing wont get rid of the leak, the gasket will have kind of a wear channel wear the leak was and so the leak will lessen but still continue.... you'll have to replace the gaskets, use the best ones you can get too, cause the blower puts more load on them obviously

I am planning on replacing the gaskets.

This is interesting. Out of all the engines I've built (well, really, only about 6-8), I've never had this happen. I didn't realize that I could get that type of leak from the intake manifold. That is, oil on TOP of the manifold.

If you want more oil drive thay big round thing on top a little higher.
Just kidding
