Sensitive process comes on reassembly the bottom half....using silcone sealant

You sure about the silicone? I rebuilt a motorcycle engine many years ago and the pro shop where I took the head to be ported and polished said to never use silicone. He said that when you put the two halves together some of it can ooze out between the joint. Then if that breaks loose in your engine it can eventually clog up oil ports and cause big problems.

I think I used some 3M yellow sealant or something that he suggested. He said if pieces of it came loose the oil would dissolve it. I didn't had any oil leaks with it for the 5 years I kept it after the rebuild.



Factory recommendations are to use black silicone. Instructions call for wiping down the inside of block for any silicone the squeezes out from compression. this keeps chunks of it from forming and falling out and clogging the oil pickup tube.
