I got the head pulled last week and pulled the oil pan tonight at work. No sludge, but the oil was thin and alot of fuel in it. No broken piston rings, but the cyl walls show signs of rust/pitting from being locked up. I have a 3 Stone and brush hone on it's way so I'll try to clean the bores up and slap some new rings on. Rod bearings didn't look the best so I'll get new bearings too. New gaskets top to bottom and I'll be putting the valve grinder I got to use also. Guessing the fuel pump is leaking into the crankcase. I'm going to pull it tomorrow and see what rebuild kit I need for that. I'll get some pictures tomorrow.
