if you said what type engines, i missed it. chevy,s are really bad to get oil drain holes plugged up. pull the valve cover and look at the back lower corner of the head. you,ll see a drain hole about 3/8 or so. run a screwdriver or something through it and clean it out. what happens is, when running, oil builds up in the valve covers and get pulled down through the valve guides. chevy,s have gotta drain !

They are Chevy's, OMC's, 350's. That'd be a nice and easy fix.
Thanks,
Steve
