Hattersguy,

I have an 82 300 TD and I have found oil in the inlet of the turbo. Not a lot of oil, but some. My explanation is that the oil from the blowby gases is separated from the intake air in the separator inside of the air filter housing. The recovered oil drains back to the crankcase through a tube in the bottom of the air cleaner.

However, no separator is 100% effective. So if just a few percent of the oil passes thorough the separator with the intake air, it will condense in the relatively cool intake manifold and be conveyed with the intake air to the entrance of the turbo which is the low point on the system.

I agree there is nothing to worry about if overall oil consumption is normal.
