So if you had metal on metal that means that there is crap throughout the engine and it needs to come out to be cleaned up and asses the bearings, no? Or did just the lifter piston fail and the pushrod as rattling around, but no grinding going on? This is another reason if I ever get to a roller cam, it will be a solid lifter. Supposedly Comp was making their own high precision hydraulic lifters due to failures from contracted ones, but it is only used in one product line, probably most expensive.
