this may havestarted with not much oil on top of engine causeing cam/soller to wear. you'll need to have a pro check this. it may be a lifter as well , try some additive for noisy lifters to see if it helps. NOT a product like STP though, there is one thatstarts with a C i can't remember the name now. it's in a quart can
