Just went to sort out my front brake braided hose which the garage failed on the MOT due to being too twisted and noticed a pool of oil under the engine.
The car hasn't been used for 3 weeks and hasn't moved.
Jacked her up to take a look and it appears that oil is coming from 2 of the exhaust manifold studs, ones with slots cut into the manifold to prevent cracking (allow expansion/contraction). There is no oil staining on the rest of the manifold (although it would be burnt off) but there were a couple of drips on these studs.
One of the studs is right about the turbo and one of the oil feeds which again (due to the fact it is a braided hose and keeps moisture) is slightly damp with what I presume is oil. I don't know if this union has sprayed oil over the manifold but I think its unlikely because there is no sign of oil on the manifold except on the studs which are visable through the gap in the casting.
Now I may be mad, but I'm sure there isn't any oilways in the manifold so how the heck is oil getting to those studs. The visable part of the manifold gasket does also appear a little moist, but again could have been sprayed from this turbo feed.
Above the manifold on the rocker cover there are no signs of leaks at all so its coming from the manifold or below.
Only about 2 tablespoons of oil has been lost but the car was only left idling for around 30 secs after a 3 mile blast back from the MOT.
I did think it was probably my oil level sender on the sump as its only secured by 3 bolts (I sheared one) but thats fine. The sump gasket looks a little moist too but there is oil on the topside of the sump flange (ie. on the block) so its coming from the top down.
All faces/joints of the turbo look clean.
The manifold and turbo oil feeds don't look easy to get to to replace
