I have a question? Today I just replaced a sparkplugs, the sparkplug wires the PCV valve and the AIR Filter, also I did oil change, and for some reason, I started to hear some knocks on my engine, they are coming from the top part where the oil cap is!
Anybody any sugestion from experience before about this problem?
The only thing I could think of is that those pistons on the engine that they go up&down are runing without OIL, like metal to metal shifting?
ps: I've had a timing belt, Power steering belt, all the seals like cam-seal etc. Replaced, also I replaced the Radiator too, not to long ago!
Please any help will be apreciatted?

What kind of noise is it-is it a clicking, tapping, thudding or thumping

It's like clapping. Like clicking, sounds like Diesel engine Noise? Like single person clapping with hands! Something like that!

Oil pressure could be low and probably not making it all the way to the top to lubricate the valvetrain-check the oil pressure with a mechanical gauge-could be a weak pump, pick-up tube/screen, oil return galleries clogged with sludge

You know! I went to a first mechanic today! He told me to take it to some mechanic who does engine clean-up. I went to second mechanic, they don't do a clean-up, but he told me could cost me around $2000. I Went to the 3rd mechanic, he told me to put STP stuff for engine clean-up, right before I do the oil change?
Any sugestion? Plz
