Ive been hoping this is'nt to bad, When I first start my car for the day the oil pressure is great and i have no tapping. When it gets warm the oil pressure drops down and the tapping starts. The tapping only happens at idle, as soon as i blurp the throttle it goes away. I pulled the cap on my valve cover and it smells of fuel. Im not sure what oil is in there now, cause it was in there when i bought the car. Im going to change the oil with 20w50 and a puralator filter. Im hoping its just in bad need of fresh oil and i have a lifter thats acting up because of it. The car has 127k on the engine, im hoping i dont have a bearing issue. Let me know what you guys think.
