Re: [OMC-Boats] Crankshaft area now?

Yep pulled both heads. Ok I'm going with option 3:

Install new gaskets, put everything back together, test for noise. If
noise is still there i'll pull out the engine and check the crankshaft
area and probably call it a season. Nice part is I shouldn't need to
mess with replaced gaskets again and should be able pull out engine w/
heads valve covers and manifold installed? Right? Otherwise it's
gonna mean another $75 for new gaskets.

In the meantime, I've dremel brushed clean the tops of all 6
pistons. Definite dings and nicks on piston 1. Also on piston6 but
way less. So something was in there at some point and unless I'm
blind it's gone now. So in theory, problem possibley solved.
Hopefully can get back together and to ramp for test tonight.
