My dad has a 96 S-10 blazer w/ the 4.3. The oil lines that go from the motor to the remote mounted oil filter always leak. He had them replaced at 25k, 50k, 76k, and now they leak again at 105 thousand miles. They leak were the fittings hook onto the line. Does anyone know of an alternative line or remote filter set up for these trucks to eliminate this problem. It's hard to work on and cost's $300 every time to get fixed. Any suggestions?
