Their customer service used to suck and so did the tech and shipping department. Don't know what it's like now because I quit using them a long time ago.That's about all I needed to see.
Widespread reports, spanning several years now, of failed lifters and cams from that company.
Too many for it to be coincidence - and I've witnessed one such failure myself with them.
I'll never use them again for anything.
The burnishing ball is smooth, it re-forms the metal so the lifter bore is round again.
I don't think the lifter bores get much wear, I think the holes get out of round after many years of the block heat cycling?
If the lifter bore are lightly rusted or the main oil galley enlarged, after using the burnishing ball, do a light hone of the lifter bore with a small hone like used on wheel cylinders to make sure the bore is smooth (and round.) I don't know if you can still buy oversized lifters for a badly worn lifter bore, but they can be sleeved if needed.
Wonder a valve was very tight then froze? Was that bent push rod on the worn lifter? Check valve lifter was pushing.
