Right peeps
Have oil coming down from the back of the sump? Plug is ok seems dry from front of car .
Could it be crank seal or poss oil seperator ?

Thanks Nik

 

How much oil are you using?
If it's not much, it could be the PS reservoir which can leak on top of the engine and make it's way to the rear with speed.
Otherwise, check the usual (drivers side cam cover) for leaks. If you're unlucky (as I was) then it could be the plastic cover on the rear of the engine behind the flywheel. If you get to the stage of taking the engine out, it's worth checking every the crank seal (it's a five minute job when you get that far) for piece of mind.

 

Cheers drips over night
cam cover already done no leaks SO i think its the lovely plastic oil seperator plate... Deep Joy :-)
