No, not all of the time. When I first start the car, I can hear it briefly. When accelerating & higher rpm's it becomes louder. My car recently overheated, I let it cool down & started it - it didn't sound good after that. The oil was very low (timing chain gasket I think). Now I replaced oil, runs & idles fine, but doesn't have as much power - along with the knock when accelerating & going up hills. Up hills really labors - car has no power. The no power thing - could this be a bad lifter? My buddy suggested bearings on main went - I sure hope not. Is that a job I can do? The Sound is more like a clack. It also does it just after hitting the gas when Im parked. Vroom clack clack vroom clack clack. I will let U know if I can isolate sound. Any help with that? Should I listen to top & bottom? Where exactly - oil pan, on the block, timing chain cover?
Thx for the reply jamesslcx.
