HAs anyone had issues with the -37 ring? It looks like it may be too thin and blow out. I am on rebuild 4 now in the last few weeks and can not tell if this is the solution or not yet. Still smoking, but I have spilled so much fluid it is hard to tell. I'm going to power wash and take it back out to see if I am still leaking. I am wondering if a -144 would be better at 3/32 instead of 1/16.
