if some of you remember i lost all oil pressure in my engine after only running it for a few minutes. i pulled it out of the boat and checked out the bottom end and found nothing. it was running ok, so i never thought to check the top end of the motor.
well guess what i found when i pulled the intake. one lifter out of its bore and a bend pushrod. what happened was one of the rocker studs came loose. i dont know how but it did, cause i loc tited the crap out of them (yes everything was clean). so that was on an exhaust valve, and the intake valve was trying to open when there was all this pressure in that cylinder and it bent the pushrod. everything else looks fine so i checked all the studs and put it back together with a new set of pushrods.
bad part is a pulled the motor out and tore it down to fix something simple. that could have only take an hour
