I have a 92 NSX and it has 23k miles and it has a loose Wrist Pin. Is there anyone else with a similar problem?

If you think it is something else please tell.

My Mechanic also used a scope and heard the noise comming from the block.

Well My mechanic did replace the Oil Pump with a computech. He didn't notice anything odd. He also did use a stethascope on the engine to locate the noise. It was comming from one spot on the engine. If I recall behind number 4 cylinder. The car does not create the pinging noise while under a load.

In my lexicon, a "ping" generally meant detonation. How about a bad injector number 4? Even under falling revs the injectors operate to reduce emissions at high vacuum.

Actually that's what I was thinking earlier but I'm not sure if where talking about a "ping", "knock" or tap like sound. But just the way the problem was described that was the first thing that came to my mind.
