Allright, started putting things back together, replaced the rear oil seal and was chasing down another oil leak up high on the rear of the block. Started pulling off the "cylinder head rear plate" located on the rear of the head and coolant started weeping out so I bolted it back down. What goes through there, I was under the impression that it was oil since I have a spare one and the passage is oily, or does oil pass through it and it also acts as a coolant block off? Searched through my manual and it only shows 1 picture of it and no description. Marlin clutch should arrive this week, want to have it all cleaned up and ready to go when it does.
