I'm new to this forum and just looking for a bit of advice on a couple things
I just bought a 94 SP with a blown motor, I picked it up this weekend and tore the engine out of it, the pto side piston is in good shape, no big scuff marks or anything and the cyl still looks good, the mag side is in bad shape, it looks like the piston melted to the cyl wall, I'm hoping not damaging the cyl wall too bad, it also looks like there might have been some material through the rotary valve because it also seems scuffed, but this is the first time I take one of these apart.

As I was taking the motor out, I noticed that the oil going into the engine was really creamy, so water got in somehow, the oil tank is still clear and does not look like it is contaminated with water (plan on flushing both gas and oil tank)

are these motors the same as the 582's in sleds?

how reliable is the oil injection system in these motors? (should I just plug everything and premix my gas?)

what else should I be looking for while the engine is out?

does anyone know where to get parts for cheap around Ottawa

any information is greatly appreciated
