Update, So Fare so Good. After flushing the engine with 20 Quarts of oil, Cleaning the oil cooler, Changing the oil pan, changing the oil feed line to the Oil filter sandwich plate and getting a 40 micron filter for the ipt oil kit i have no issues. just installed a G/S TMIC in December no tune yet (soon) on the first turbo i didn't hear any spooling noise but know it sounds like a plane is about to take off. you live and learn, next up fuel pump and injectors and I'm done.
