Thanks, I'll check it this week. Hope thats all it is

Hello, ya better check the valve springs, the inner coils break, triple springs & the crane roller lifter thru pins can come loose and the lifter can get jacked in the block and break and start eating the cam up

Check the little things first, and the coil would be a good place to start they can do funny things when they get warm-hot

Thanks for all the help, it was the coil causing the problem.
