After I returned home I parked on the driveway whilst I was let the missus into the house. I then moved the beast into the garage.
In the morning I found a damp patch of oil like substance on the driveway and a few spots leading up to it in the path that I reversed down. Guessing from where the car was when I let the missus in the house I don't think this is coming from the engine.
I checked under the car in the garage and no further liquid has leaked overnight.
From my estimation it would put the rear diff in that sort of area? Any ideas about what could be leaking? The liquid was quite black and didn't have much of a smell.
The differential on these cars are virtually bomb proof. They do weep slightly from the fill /drain bolt, but I have never seen one drip.
This would mean a leak from the input shaft lip seal or the output shaft seals.
They only leak if the diff has overheated, & I mean seriously overheated.
To carburise a seal made from Viton or flourocarbon would require bulk oil
temps over 160 C on a regular basis.
Could I suggset jacking the rear of the car up & cleaning the differential.
Whilst you are there, look above the diff & see if the self levelling accumilator or the pipework to & from it is leaking.
These things rot & dump hydraulic fluid all over the diff.
They do go after about 10 yrs.
If it is not this then at least the diff is clean & you can then run the car & trace the leakage.
