if it's a tapping noise and from the upper engine, it's probably a lifter

if it's a knock sound and from lower engine, you may as well start looking into a turbo, high performance engine rebuild parts, and cams. cuz if it's lower engine you got rod knock and that's lethal on an engine. causes grooves on the crank and it's not worth repairing...may as well replace. but on second hands, gives you a real chance to dig in there and get parts.

the car sittin had nothing to do with your problems. unless it's just that sludged up.

Thanks, for the advise. But if it is the lifter, is it then serious , and how should I relieve this noise?
