A relative passed away and I'm considering buying his car, a 1985 190E
with 2.3 engine and 82000 miles on it. It runs very well but needs a
quart of oil about every 1000 miles (using 10W-40). The oil doesn't seem
to be dripping on the floor and I've driven it quite a bit and have
noticed no smoke in the mirror. I notice what smells like hot oil after
driving it. Good thing it has that "oil level" light!
I notice from the maintenance records that the M-B dealerships had been
consistently putting 20W-50 in it.
Is a quart per 1000 at all normal for this vehicle?
Since you smell hot oil after driving it for a while I would suspect a leak
at the valve cover gasket or the front timing cover. The reason you don't
see any oil on the floor is that the drip pan/noise shield under the engine
is probably catching it. This is where my 1992 190e 2.6 had leaks.
My in-laws bought it new, so I'm sure the mileage is correct.
Unfortunately, my father-in-law took care of the car and he's passed
away now, so I can't get any info regarding whether this is a new problem.
Thanks for the input!
Okay... that is good enough of a proof. Then I would say that the valve
seals are shot due to aging... It is fine to drive as is but eventually it
will clog your cat converter if not yet done.
It is not that intensive of a job to replace the seals... but in any case,
do not let anyone convince you to do the entire head job... that cost alot
more money and just a waste of your money.

Locate and fix any external leaks like the valve cover gaskets and
switch back to 20-50, and see how it goes...

That is a nice feature...
