I am thinking about using fullboreonline.com to get my 951 cylinder/s cleaned up and new pistons. But before I do this, I want to make sure the crankshaft and counter balance is in good shape. My first motor rebuild. So I turned the motor over and removed the mag cover and loosened all the bolts. I realize the bottom cases are sealed together with sealant. But for the life of me, how do you get them apart?? I found a small slot on one side and I can budge that spot but that's it. I also tried to get the cylinders off with no luck, same sealant, same stuckness. What am I missing?
I also have another question...only the mag piston is pitted, with 3 score marks on the cylinder wall. But the head is pitted to, do I need to find a replacement? No one seems to offer a machining service to clean that up.
