That seems like a reasonable life expectancy, especially when you
don't know what the PO did.
In spite of the fact that my turbo came in minus a stud, I'd still
getting your turbo from Rusty. The fact that he has had ZERO returns
over a lot of years tells me they are a good rebuild.
I took cell phone pictures of the red goop all over the oil inlet of
my old one. Some year when I get the photos off my cell phone I will
post them.
I have decided I'm using part of my bonus this year to buy a rebuilt
turbo for my 87 300D -- same symptoms (blue smoke on startup,
excessive oil consumption (worse on the highway) and definitely
lethargic turbo response when cold, all the same problems I had with
the 85 Volvo TD when it's turbo went south.
Oil coming out the front of the turbo (as in still getting oil blown
into the intake (with the crankase line removed) can ONLY be the
front seal on the turbo. Easy to check, just verify that the blowby
isn't bad enough to use that much oil. Mine has more than I would
like, but not enough to lose a quart of oil in 500 miles! Usually,
there is oil leaking into the turbine side as well, and that burns
in the exhaust making blue smoke.
Odometer just rolled over to 300,000 this week, and is at least
60,000 miles short of true milage, maybe 70,000. I'm not upset the
trubo has gone south at nearly 400,000 miles. Seems to have good
compression, too, although I'm not too sure about the head
replacement done before I got the car 5 years ago.
