    OK, so I got your attention...

    This sound appears to be coming from the back side of the engine. The sound "acts" like over advanced timing on a gas engine, that being it comes and goes depending on engine load. However it sounds slightly different.

    It started about 2 months ago. I had done nothing to the engine before it started. It just started on its own (as far as I know).

    I have about 160,000 miles on it and have yet to do any service to the inj pump or the injectors. I have no idea if the PO did anything either.

    I hope all I need is to look at the timing marks. The only other thing I can figure is a injector is going bad or the pump.

    Any thoughts??? /forums/images/graemlins/1zhelp.gif
