I should have added that I did the diesel purge and its amazing how quiet it was while the purge was burned. Being a noob to diesels thought I had this problem licked but sadly nope.

Even did a series of Italian tuneups here in Estes Park whre I live at 7600ft elevation. The car runs amazingly fast even at high elevation and got it to blow lots of black smoke but that could be Alda and altitude.

Then did MM oil in crankcase, and ran it hard then changed th oil to Rotella T and put a Mann filtr in. No real change in noise.

At a dealer, had them change the belt tensioner, shocks, motor mounts and transmission mount. That helped a rattle and shake but not the noise I described.

Next, I think I need to send the injectors off to be popped and balanced. Need to changed the vacuum pump and look at timing chain and guides I guess.
