I have welded up cracks on two Canton pans near the rear seal . These were on both one and two piece rear main gaskets for c-4 corvette .
Looking at the moroso next .

My first Canton pan was damaged when my timing chain broke through the bottom of my timing chain cover and grabbed the front lip of the pan. I got that pan many years ago and never had any fitment problems with it.
The bolt holes on my recent Canton pan didn't line up which is making me question why the quality wasn't there.
Honestly don't think I will go with Canton for my next pan.

I was using canton oil pan stud kit...and I think that's what causing my problem which not getting torque properly....I had oil leaking around an oil pan stud....removing those and going with the Fel-pro kit...think it will solve my issue..

No need to do that --- just make sure you put a dab of gasket sealer on each stud before running it into the block... otherwise the oil will climb the threads and you'll never stop that.


You can remove the studs and do it while the motor is in the car - it just takes time! Before your next oil change --- pull most of the studs --- use some brake cleaner with the little red "nozzle" and squirt just a bit into each hole -- watch your face and eyes!! The use a q tip (I buy these with wood sticks instead of the ear cleaning type) and use that with just a little brake cleaner on it to just run around the threaded hole... ONE of TWO q-tips per hole... Clean the stud -- add a dab of gasket sealer (NOT SILICONE SEALER!!) and run them back in.
