Patterson and other fellow gearheads,

Congrats on the relatively painless fix!

One quick question about that noise--
I have a tapping sound not related to valve clearances (they are set to within + - .001" of specs).

I don't want to tear into my engine without due cause, but I wanted to ask about the noise you had.

Was it present at all throttle settings, or did it go away while coasting? Mine is almost silent while coasting, but even the slightest pressure on the accelerator makes the tapping noise reappear.

My engine's oil consumption is better than 2K miles/quart , 239k miles, 23-25 mpg no matter what speeds.

I REALLY want to rule out a wrist pin, but am not sure if it isn't a bad injector or an exhaust leak as well.

Any thoughts?

Much appreciated,
Nate
