We are sending the lifters to Isky on Monday. Its not an oiling problem as the whole upper end (rockers, etc.) is fed
oil thru the pushrods via the lifter and the rockers were getting plenty of
oil. I've heard nothing but good about Isky red zone lifters. It's probably one of those "gosh this is the first time this ever happened" things which would be par for the course. Isky has a great reputation and I'm sure they will take care of this. My only concern was if anyone else had this problem.
