Officially is a Universal 35 hp marine diesel in a sailboat but the block is Kubota. Pretty bad oil leak at the pan gasket been going on for many months (absorbent mats down of course), just now got around to finding the source... drops coming from gasket about mid way on one side. No way in hell to get a torque wrench in such a tight space or a standard 3/8 socket wrench for that matter, so used a small box wrench (10mm) and tightened all the bolts on that side as best I could.. None were loose and suspect they were already at spec torque but I managed to turn them another 50 degrees.
This helped...alot...but still a small drop leaking every 50 seconds. So the question is, given the PITA factor of getting into that cramped space, should I try with longer wrench to get them even tighter still or is any further leak reduction probably not going to happen ?
(And yeah I know, ultimately it really needs a new gasket....but replacing the gasket would be a major PITA given the fact that the pan could be lowered but not removed...probably would require raising the engine a few inches. Also the boat is for sale, which is the only inspiration to do what I've done ! )
