Re: 356 connecting rod oil hole

Wow! Thanks guys for the rapid response and info. Yes, there is a slot on the piston skirts of the original and replacement pistons. I believe the squirter holes should still be there. Ever who restricted them in the past may have caused the damage that did occur to this engine. This engine is from a new owner who just purchased the car, so history is unknown. It has approx 68000 miles on it. The engine had a replacement cylinder head and newer bearings in it. Don't know why these had been replaced maybe an overheat or ? in the past. Engine was taken out because it smoked (alot) and ran rough. We found the cam was worn (like an old small block Chevy), lifter followers were torn up, and hyd. lifters were seized in the followers. Pistons were scuffed and cylinder bores were worn. Also valves and guides were worn. We also found a connecting rod that was "S" bent and twisted. The damaged rod appears to have been there for awhile, beacuse of the lower wear marks at the top of the bore on that cylinder. I believe the cam/lifter situation may have been caused by the restricted squirters. I have done a few other 356's in the past and always noticed the squirters were open. I was wondering about the squirters being closed off on this engine. Thought maybe someone could explain it, because it seemed wrong to me. Looks like on Thursday I am drilling out squirter holes! Thanks again, Craig
