I just started my new crate engine (383)for the first time this morning. It is smoking at the exhaust manifold where it connects to the exhaust pipes. I assume I only need to tighten things up. No leaks present any where else.
How long should a new crate engine smoke during break in? :confused:
I assume it's just burning off like it should considering all new gaskets etc..

Thanks, Mark
