Is my clutch slipping ? '93' 940 manual

[Robert]

Advice and guidance please.
I have a '93' 940 2.0T estate, 123K manual 4 speed with overdrive (5th). I
have had this veh for last 6 yrs, no probs except general wear and tear of
replaceable items etc.
When I first got the veh I made a mental note of the various speeds and
respective rev readings.
Over the past couple of months I have noticed when climbing hills and
performing a quick overtake the engine speed increases but the veh speed
increases slightly. If I ease of the accelerator pedal the revs come down
and the veh speed increases. During normal driving the speed and rev
readings are virtually the same as 6 yrs ago.
I am not heavy footed nor do I drive with my foot 'resting' on the clutch
pedal. I use the hand brake when stationary eg traffic lights not the use of
the clutch to keep the veh stationary. The movement and 'feel' of the clutch
pedal appears normal.
I cannot remember the details or the date but I recall another owner
mentioning something about it not being the clutch but something to do with
the injectors.
I also have a leak from the rear seal approx 2pts syn' oil per 8k. Not being
mechanically minded would it be best to have oil seal and clutch replaced
together.

bearing in mind that the rear oil seal and the clutch both live in the
same bellhousing, I'd say it is a safe bet you now have to replace both.

Robert,

If the engine speed increased but the speed didn't as you depressed the
accelerator, guess it would be the clutch, don't you think? Hydraulic clutch
leak? or worn out clutch and of course if you need a new clutch, it would be
an excellent time to check all the seals etc. and replace as necessary

That is pretty typical behavior for a worn out clutch :-( If that's what
is happening, it will be worse every week and won't be usable in a month or
so.

I recently experienced the same thing on my VW...I took the clutch out
and it was not worn but oil soaked and the pressure plate was glazed
with heated oil. I traced the oil to a leaking valve cover but I bet
your clutch suffers the same problem and the oil is from the rear
seal...no use in changing the clutch without addressing the rear seal.
By the way the oil soaked clutch needed to be replaced but the pressure
plate was could be machined. Good luck.

Normally the clutch friction surfaces are separated from the rear seal by
the flywheel. Some pilot bearing holes go all the way through so traces of
oil could conceivably migrate through there. I've never seen oil from a rear
seal get into a clutch.
