Good advice from all.

I will pull piping and check on Thursday afternoon when I am free. The grinding is definitely from inside the rear turbo itself. Smoke wise, is coming directly from the rear turbo because it is not coming out of the exhaust least in the front downpipe (also need to fix this). Engine is running great to my knowledge. On the HHH logger I get no knock and all sensor and injectors look and run fine to me. Both O2 sensor even rear the same. As for the white smoke, I almost think it is the seal inside the turbos that went, and my shaft is free spinning and griding, therefore I am leaking oil or coolant into the hot exhaust side. I was looking on 3SX and their rebuild kit on their site had a good desciption of my potential problem. Check it out:

I will check piping and shaft play and get back to you all. Anyone got a rear turbo without shaft play sitting around for dirt cheap (just in case)?
