Oil from 200tdi

Hi all.

I have a 90 which has had it's engine replaced with a 200tdi. The
engine has been spewing out oil from the breather pipe since it was
fitted and I've just got it back from Simmonites who sold it to me.
They have tested it for crankcase pressure etc and can't find a
problem, they found plenty of other problems with the rest of the car
(

When I collected it this weekend they had put a clear plastic bottle
on the pipe and taken it for a 50 mile drive. Not a drop of oil.
Excellent I thought, they've fixed it. I drove home, about 180 miles,
along motorway and dual carriageway and checked the bottle at home. It
had about a centimetre of oil in it. Is it possible it's only
happening at speed? My brother had a 200tdi disco some years ago that
spread oil over the back door if he sat at 80. Numerous trips to the
dealers never resolved it.

Is this a problem or should I stop worrying about it? I do a fair
amount of motorway driving in it as Norfolk is some way from the
hills, any hills. )

Has the engine got the right dipstick fitted? You're not inadvertantly
over filling it are you?

Is the engine mounted in the same orientation as it should be? Not
tipped left/right/up/down?

I'd be inclined to leave the clear bottle in place and see how much oil
actully comes out. It might be less than you think as a little drop
makes a lot of itself!

The 200 TDi should have a closed breathing system, not one that vents to
atmosphere. There should be a cyclone, metal or larger plastic depending on
age, fitted to the rear left [looking from the back] of the rocker cover.
From the bottom there should be an oil drain connected back to the sump and
from the side there should be a pipe carrying dry gas to the inlet air
pipes.
If it is vented to atmo then you will likely lose oil. If plumbed properly
then all oil should just drain back into the sump.

Hi Huw

Sorry for the delay in replying

What you describe is as fitted to my tdi. The oil is coming from the
pipe that would normally be connected to the inlet air pipes.
Simmonites disconnected this and added a plastic bottle to the end to
show me that it doesn't leak oil. 200 miles later and it is leaking
oil. They seemed to have ignored the fact I showed them the oil
dripping from this pipe when I took the car to them in the first place.

Certainly for the metal, and I would think for the larger and more efficient
plastic version, there is a service requirement for these units. This
consists of periodically removing the unit and giving it a thorough flush
and internal clean. Having done this all the oil should drop down the
downpipe to the sump and not into the intake pipe. An overfilled engine
might overwhelm the system but generally it should not breath enough to
cause a problem.

A small amount of oil finding its way into the inlet should be no problem.
The fact that you have disconnected the pipe from the inlet manifold and
ended it in a bottle will almost certainly adversely effect the efficiency
of the cyclone as the speed and volume of air in the cyclone will be less
than needed to throw the oil against the outer wall to effect separation
from the gas. So in effect you get a false reading from the bottle.

Thanks for that info. That gives me something to do over Christmas )
