sorry anthrax you are incorrect...had a chance to pull the turbo off yesterday while sitting around for 6hrs while sinister told me he was right down the road and almost here to pick up the car(big thumbs up for ya matt)...was indeed a piece of the valve seized in the exhaust wheel. I left the o2 housing on when I pulled the turbo so I guess it was hiding somewhere in there...On your theory Im not sure how pieces of metal would get from the oil pan to the turbo cartridge, as they'd have to pass through the oil filter....but then again with dsms anything is possible...none the less car is still for sale, everything is ready to go including now a brand new $80 titanium battery purchased yesterday.
