wat can it be …….

Tap tap tappits!

Or shot crank bearings, which you really don't want.

Most likely hydraulic tappits

how much for new one 's

50% cheap oil mixed with 50% parafin,best engine flush,just let it idle for 5 mins and drain out,new oil and filter and try that,works well with noist ford cvh engines  :wink:
