Not high enough frequency for piston slap IMO. Pull the belts off and run to eliminate idlers and accessories.

Hmm no I didn't think it would be piston slap in one if these to be honest.
It did sound like a low oil pressure type bottom end knock but if it was worn bearing(s) it's normally worse when hot and the oil thins. UOA I just got on it was flawless too!
Only thing that makes sense is an oil supply issue or dodgy filter but it has done it on 2 filters so far (both same Ryco brand)
