Title: Oil leak - probably rear crankshaft seal
Post by: wakeyomega on 01 April 2009, 09:40:29: Hi All
I have developed an oil leak at the rear of the engine with drips from the engine to gearbox area. Although its an auto, it is definitely engine oil and I'm 99% convinced its the rear crankshaft oil seal. (and its definitley not cam covers and my breathers are clear).

I've done 155K and she is 8.5 years old. I've seen just a few threads with suspect crankshaft oil seal problems, but unfortunately they are not complete, so no resolution is recorded. My question is, have many others experienced this? Is there any wise words of wisdom on this problem? or am I , as I suspect from the lack of threads, one of a few with this problem?

Thanks Pat

I'm guessing that, as I've only had a couple of pms on this, a rear crankshaft seal failure is a very rare occurance on an Omega, and no one on the forum has suffered one?

I'll feedback on the link when its sorted (hopefully).

Post by: wakeyomega on 26 May 2009, 11:31:36: Just thought I'd update this thread to assist others with the same symptom. The leak DID turn out to be the crankshaft rear oil seal. The leak was exactly the same as the picture in this thread from Entwood.http://www.omegaowners.com/forum/YaBB.pl?num=1223978808, and is fully resolved with a new seal.

Is it easy to get too and fix ?

THINK I might have the same problem BUT I have oil around the oil filter also. Did you have the same problem ?

No oil around the filter so I'm thinking you may have something different (and hopefully simpler to sort out - could it be the oil cooler pipes? has the cooler been changed in the past?).

I didn't fix it myself, wimped out as the thought of heaving a gearbox around to get at the seal put me off (might have strained my golfing arm!), but we have a great bloke in town who is a gearbox repair specialist and he did it for me at what I thought was a reasonable price.

Good luck

Post by: Entwood on 26 May 2009, 23:35:03: If you don't mind me asking .. how much ??? Mine still leaks about 2 drops overnight after a run, if not used it doesn't leak. So looks like the rear crankseal to me, even though I can feel nothing inside the little rubber bungs .. :(

At the moment I'm living with it .. but it does need doing and I don't have the facilities to drop a gearbox .. :(

Post by: wakeyomega on 27 May 2009, 08:35:10: The chap here charged me £230 + parts (which were £13!). I was more than happy with that. Mine was dripping only slightly more than yours, I was fed up of oil stains all over the drive etc. and knew it had to be done.

Good Luck

Post by: Pete Elite on 13 August 2009, 23:14:13: When i was underneath the other day checking the gearbox fluid i also noticed oil drips on the 2 torx bolts but didn't really think much of it as it didn't seem to be bad enough to worry about :).
