oil contamination?
Just had turbo rebuilt. The rebuilder said the bearings were shinny, polished he said oil contamination was the cause. I do agree when I changed the oil the same day I pulled the turbo off the oil was thinner than normal and smelled like fuel. What should I look for Injectors leaking how do you test? My wallet can't wait to go on this next roller coaster ride! Sucks

send an oil sample to blackstone labs, i do at least one every oil change for that very reason, 22.50 and they will tell you well before you notice if there is something wrong with the oil...e.g. fuel contamination

click on the word "tools" in my first post for AE..very handy to have...blue smoke is oil....i would try out the new turbo and see if the blue smoke stops..go easy on the new turbo for 50 to 100 miles..let her break in..if you do a oil sample..i would send one in at 3000 Miles...let us know how you turn out after the turbo swap..good luck..
