running wvo in your tdi can cause polymerization of your motor oil = particles of sludge = bad for turbo bearingsWell I've had another set back with my turbo. I just heard back from the shop that I have some kind of contaminants in my oil. There are grooves big enough for a fingernail to get caught on the turbo bearings. Oil contaminants is not covered under warranty. My turbo guy is recommending a pre-oil filter without a bypass before I install the newly rebuilt turbo.
Has anybody else had any issues with oil contaminates or ways to prevent something like this happening again. This turbo is beginning to be a big money pit.
