Front oil seal on 1984 245DL B23F AUTO/OD[ALL/1998] posted by Sam on

The front oil seal started to leak yesterday, oil around timing belt cover
and blowing back to the manifold (burning smell). I looked in the Bentley
about replacing it and the timing belt. The first thing the manual says
is to check the flame trap, it may make a good seal leak. I am going to
replace the flame trap tonight. My question is if I replace the trap,
would the seal "reseal" itself once the preasure is back to normal? If
the timing belt is not oil soaked I may not have to change it either.
The Bentley says a special tool is needed to press in the new seal. Is
there a method to press it in if I don't have the tool? Thanks.

Cross your fingers. The leak may go away if the internal pressure is relieved. To install the new seal, I have used a 2" PVC (solvent weld type) pipe coupling which is about 2-3/4" OD and 2-3/8" ID by 2-1/2" long. I placed a large washer over one end of the pipe coupling (tape or glue into place). Use the center bolt with a washer or two, through the hole in the big washer to press the seal into place. One caution! Before you remove the old seal, note how deeply it is pressed into the case. Don't press your new seal any deeper (and it will go deeper) than the old one or it will leak like the proverbial sieve. Good luck.

Pay particular attention to the entire breather system. If it gets blocked,your car WILL leak oil. Then if you put new seals in they will probably pop straight out. Good fun stuff. I clean mine each 10 000 km (it gives you something else to do whilst the oil is draining). Give the entire system a clean out in hot soapy water or petrol (whatever your preferred method of ruining the environment). Possibly replace the calibrated nipple (the thing that screws into the top of the inlet manifold), they are very cheap.

I changed the Flame Trap and cleaned out all the associated plumbing and
nipple on the manifold. The leak seems to have stopped. I will drive it
for a few days to verify the fix. This car is my brothers and I will have
it for a few days. I noticed that it dosen't idle well when it is first
started or if it sits for a while. I checked all the vacumn hoses and
don't see any cracks. After it warms up it idles ok. I cleaned the
throttle body (on the car with a rag soaked with carb cleaner). It did
not make much difference. What suggestions does anyone have? I would
like to get it resolved for him before he returns. As always, thanks.
