May 18th, 2003, 10:11

Just had new Mot,everything Ok. Put car on market same day as have new car.Wife drives the car next day oil leak at the rear of the engine.The car runs great no problems.It has 91000 mls on the clock.I looked at the flame trap a couple of weeks ago and it was in a bad state,so I cleaned the pipes and decided not to put the flame trap back in (as read in Forum).Has this anything to do with the problem.I took car to garaged he looked at it and said "Crank seal gone", it will cost about £350 to do but it might not solve the problem.It could be a blocked breather!.The car was not overfilled and seemed Ok before.I want to sell the car but not with a problem. Can anyone help?.

Hmmm... oil leaks! I assume that the oil that is leaking is engine oil and not gearbox oil then.
Best thing would be to steam clean the engine all over and underneath if possible, drive a few miles afterwards and get the engine warm then park up and place some sheets of clean paper or an old sheet under the engine. Drips seen will indicate where the oil is running from.
Another way would be to park the car up on some ramps or stands and to crawl underneath and watch for signs of oil leaking.
Anything leaking from the bottom of the bell housing would seem to indicate a leaking crank seal but be aware of any oil that might be leaking from further above and running down.

Try checking your camshaft rear oil seal for leaks.
Several years ago, shortly after buying a 240 (2.3) the engine camshaft oil seal blew, squirting oil all over the place! On investigation, the breather system and flame trap were clogged. The camshaft rear seal was replaced, the breather system was cleaned, including all rubber hoses, and the flame trap was renewed. No further trouble since - but always check the breather system on every main service. If it should carbon up there will be too much pressure in the crankcase, which will cause oil leaks, and maybe seals to fail. You might also check security of the oil pressure switch and associated pipework. Good hunting!
