The only accessory the motor runs is the altinator. The cooling water comes in from the jet pump. I'm pretty positive it is not the starter hanging up. The plugs all look good on the motor. I just replaced the ignition and had pulled the plugs and looked at all of them prior to replacing it. I had the motor rebuilt about 5 years ago and at the end of that summer I did have a piston hit the valve. I took it in and they cleaned the motor out and put a sleeve in the cylinder. They had replaced some parts. I don't know what they did but they didn't do a very good job the 2nd time around. They were good at taking my money though. The past 3/4 years I have been chasing down problems when I get a chance. Last year I pulled the heads and installed new head gaskets and intake manifold seals because it had problems with oil leaks from the manifold and cooling water leaks into the oil. This year I replaced the ignition and sealed up an vacuum leak in the timing cover. I just need to find the source of this squeak so I can put an end to this nightmare.
