Tapping noise from engine.
hen i crank up my car there is a distinct tapping noise that sounds like a lifter ( trying to give a comparison for sound) it does increase with rpms but gets unnoticeable after about 1200 rpms. I need to run the engine a while and let it get up to operating temp to see if it remains. Any clues? Is this a "normal" sound for these engines? Its not real loud but you can hear it clearly at idle tat-tat-tat-tat-tat...

When mine starts making a ticking (upper eng) sound it's telling me "it's time" . I go beyond the "change oil" notice on the dash.

Re: Tapping noise from engine.
I had the same noise. Talked to a bud who builds race motors, he said to warm up motor to operating temp alowing it to idle. Noise should decrease as engine temp comes up. My noise went away. Cause/ oil bleading out of a lifter after extended non use of car, 6 months. Hope this helps!!!

When I first got mine I had to use an engine flush. It's basically a quart of diesel fuel that is run for 20min? Can't remember. Then you drain and fill with fresh oil.

If there is a next time..... check the oil pressure ! If the oil pump is beginning to fail and you see low pressure when the noise occurs, shut down and pull over. There have been stories of same.
