Draiveshaft / Oil leak problem
14. Jul 2006 at 11:56

Had a good look under my car yesterday to find the rear drive shaft coated in oil or something

The rear of the driveshaft unit seal there is no sign of oil its all on the front hope this makes sense.

Should I be worried?

Also I have been getting the annoying 'oil lack' coming up on the MID quite abit recently when parking on uneven roads and sloped drives. It looks like a possible sump gasket leak but not sure as when my car is parked outside the house there is no signs of oil on floor or anywhere else I park. But when I look around the edge of the sump its coated in thick nasty horrible stuff.

Does the gasket sound like the culprit?

On a good note I think I may have solved a rattle problem I have had since my clutch change, I found the heatshield near the centre exhaust join was sagging down and hitting the exhaust, new nut and washer and fingers crossed its sorted.

Any advice on the above problems would be most appreciated.

Yeah was thinking of cleaning it lost the daylight though.

The oil lack goes when on the level.

I gues it could be the remainder from when the rocker cover was leaking.

Shall have another look tonight.

Cheers for the response.

Checked the car the other day to find the oil was still ok, but yesterday I took some mates to Heathrow Airport and half way down the M25 the 'Oil Lack' came on the MID, my thoughts are a leaking sump gasket as there was alot of crud around it when I last looked shall be sourcing a sump gasket for the weekend and will be doing a full oil change so fingers crossed this is my problem.

Back to the rear driveshaft unit leak has anyone got any Ideas on what this could be?

Cheers Mark DTM Just hope a change is not needed sounds lethal if done wrong.

Jul 2006 at 16:26 I suggest you get underneath with some Gunk or similar and clean the whole area of old oil and crap, then keep an eye on it for a while. Once it is clean then any fresh leak will be obvious and you can decide if a new seal is needed.
