There is no such valve on the return lines. Its just a hole into the
oil pan.

Tell me more about the foot valve. Is
Have you verified the amount of blowby your engine produces? You may
also want to temporarily divert the blowby hose to a coffee can and
drive a bit to see how much oil is blowing over.

If there is a foot valve in the return line (and there has to be

end of the tube.
It's pneumatics. Both top and bottom of the oil separator are exposed
to crankcase pressures. Gravity breaks the tie vote. (The hose to

What is the condition of the oil trap in the air filter? I believe you
said it was OK, but don't remember. If split or leaking, it will dump
quite a bit of oil down the intake -- ditto if the valve at the bottom
of the return tube is bad, it can actually suck oil up out of the
crankcase at
WHA? Valve at the bottom of the return tube? Didn't know there was one
there..are you talking oil return tube???
The oil trap was swapped out with one from the 74kmi '82 300D and no change.
Turbo has been swapped also.

Yup, there is supposed to be a foot valve on the air filter oil return
line, I do believe (although I've been wrong a lot lately).
The guts have to be in place in the oil trap, too -- it's a
centrifugal filter, so the inlet pipe must be at an angle. Don't
remember what it looks like any
Ok, so it's an old subject, but Kaleb's posted the question to me several times
about the cold starting on this car. This morning it was 13 degrees when I
left for work. Glowed for 15 seconds (counted by the ticking of the dash
clock) and turned the starter right after the glow light went out

Look in the air filter, you should see gobs of oil in there from where
the line from the vac pump goes in. If not, then there is some other
problem with where the oil is going.
I have a writeup here on rebuilding my vac pump.

Really, I've seen that hose on the older non turbo 123's, but haven't noticed
one on my CD. I'll have a look tonight after work.

Nope, no gobs of oil in the air cleaner. No vent out of the vacuum pump, only
the main hard vacuum line. My vacuum pump looks identical to the one
in Hans's
300SD. I'm still not convinced where the oil is going..

It's burnin', burnin', burnin'! Either that or there's some kid sucking it
out at night while you're sleeping. Seriously, oil in the vac lines could
be the source of the problem. You still haven't found any obvious signs of
oil anywhere
I can't see how it goes from the vacuum pump to the engine on this car. There
is no vent hose to the air cleaner, the IP shutoff valve is new, and
the EGR is
blocked off. Where else is there to loose oil? Could it be an IP seal
sucking
oil in and mixing it with the fuel???
