Being the OCD person that I am thought I would check the condition (crap in the sump) while I had the winter to do it. Drain/suck the oil out, remove all 4x 9/16" nuts and remove the sump oil p/u tube from the pump head and off it comes. You might have to fight the bilge pump for room, but I took mine out to save some skin. It appeared that during the casting process the face of the sump had 2 depressions on the P/S sides from pouring the casting I am guessing. Anyway I decked the face with a fine file sanded it with emory cloth cleaned it all repainted as needed and applied a thin skin of RTV to reinforce the seal. Put it back on and tried to torque it as much as possible with the space available. Refilled the oil with 30W it took @ 1 QT. BTW if you suck out your oil, the sump p/u hose is coneected to the sump screen and it the lowest point on the drive so you will most likely get all of the oil out during servicing. Looking at the overall condition of the oil after 330 hours it was like new. If you change your oil as required I would see no reason to have do anything out of schedule.
