i acquired an engine in a trade. it was "supposedly" rebuilt. i did a test run on a stand and the rear main leaks. i reshimed after using a plastigage... still leaks.
i pulled the oil pan today and looking around i noticed each piston had a slot hacksawed in the skirt almost up to where ring groove would be. also looking down in the pistons (engine is upside down on stand) there looks like a 10/32 threaded hole in the bottom of the wrist pin area of the pistons. i have no idea what the guy was doing, any ideas? it would be nice to have this for a spare engine, but it looks like a complete tare down and rebuild.
