Yeah, saw that one, thanks. My tech said the same thing. However, many of the M112 and M113 engines are only now getting up into the higher mileages and I wonder how long the seals will last, and whether things like this will begin to surface? My M103 still had original everything at 300,000 Km+. I don't think these engines will fare as well.

I am hoping it is sludge build-up and that the cleaner/additive will flush it and help improve the problem. The consumption/smoke is still very minor, but I want to tackle it now. Like I said, I've only seen the smoke on startup twice since I bought the car this past spring. It doesn't show any smoke while driving, or when starting after sitting overnight. It's only been after it has sat for a couple of days or more.

uberwgn - thanks, my tech has an additive they use just for this purpose. He said sludge build-up on these engines is common, esp. if the intervals have been long. He recommends changing oil every 10,000 Km and the tranny fluid every 50,000 Km. I'm inclined to agree.
