I'm guessing there are top-end issues. White smoke at idle, varying between moderate to cloud cover, gray smoke with compression, oil into the air filter, and after running a top-end cleaner i've now got a leak near the oil pump and it tried to run away on me when pulling into the shop. Low power and the fact that the PO overfilled the oil by 2qt doesn't bode well either. I'm expecting worn rings/pistons as the engine has a tick under 130K on the odo, lifter seals at least.
Cleaned up the shop yesterday so that I can dig into it a little today and tearing it apart next week. I'm not well versed in the weak spots on the Td as all my other engines are 300Tdi, but everything I've heard says there are potential block issues to be concerned about.
