anyone out there every get water in oil from exhaust sucking back??
ok long story short ive been up down and all around done everything, heads rebuilt, check for cracks, new gaskets, now I pulled the motor and had pressure tested no cracks in the block hold solid pressure!!
there 565 bbc with cams and old hawk manifolds with jacketed tail pipes with tips, pressure tested the manifolds there holding fine... heard a wise tail about big cams sucking back water where the water and the exhaust mix... the only catch is mine mix at the tip outside the boat, not to mention I have velvet trans so its about 3ft from the manifold to the tip
has anyone else had this problem im running out of test to perform???
any input would be apprieciated

Yes it happens all the time, the exhaust should't mix with the water they should be dry all the way out. Big cam race motors are completly dry the run a dump tube out the top or bottom away from the exhaust.

check the exhaust gaskets on the water one,,a small leak will make it revert.

What heads are you running, what exactly is the manifold, could be an intake gasket leak and running into the lifter galley
