Well as mentioned I did snap a vacuum hose on the 92 300TDt and
replaced it with some stock at hand, but at the time I noted it was
larger size tubing. Not the same as the snapped smaller diameter
tubing. However on the other side of the pot feeding the transmission
vacuum line was a flow restrictor so I thought perhaps it won't
matter. Sigh. Of course it did, shifting became *rather firm, er
really really firm*. So off to the dealer to get some proper diameter
vacuum tubing, which I installed today and things are back to normal.
This car also has the residual heat system, press button after
turning car off, and it runs fan and pumps heat into the car until
the temp goes under a certain value, or a time limit is exceeded.
Problem is that didn't really push hot air, cold air was more like
it. Prowling about showed the aux circulation pump was toast, no
turning, but has voltage. That I replaced today and system works as
expected.
Lastly oil Leaks, we suspect a minor oil leak from either the upper
oil pan seal, or the rear seal. Both of which are major work, remove
engine from car type of work.
Are these leaks normal for the OM603, should I just resort to
cleaning the lower noise/wind shield once a month or so? & toss the
funds at the university kid under the roof.
While it CAN happen, leaks from the oil pan of OM60x engines are rare.
Much more likely to be leaks from the injection pump seals and gaskets,
the intake manifold runner going to the #2 cylinder, the head gasket
(especially above the alternator), the timing chain cover, the front and
rear engine seals and the front seal of transmission.
