Is there a diffrence between the oil cooler gaskets on the International 7.3 and the Ford 7.3? My Dad got gaskets from an International dealer and "fixed" the leak. Started the truck and drove it no leak. Next day, started the truck it leaked. Dad talked to another parts guy he said the gaskets are different. He checked to make sure the bolts were tight cleaned it off drove the truck again and no leak. The owner came and got the truck drove it for a week and it started leaking again.

Any ideas?

Thanks,
Paul
