    Oil cascade , down front of the sump

    Looking for pointers , what looked at first to be the sump plug 'weeping
    is, actually oil dropping from higher up , running down the sump face

    Other than the sump/block join, what other possible causes in that area ?
    top of the engine looks quite dry , whats located low down at the front
    of the engine ?

    Thoughts ?

    Tnx -G

    Enough to leave marks on the road over night , its wet , but not at waterfall levels
    had quick look during the mot*, but , couldn't see where it was originating ,
    initially , thought had hit the sump on the deck

    It running down the front face ..

    good point, the pas cooler is in that area as well

    the various diagrams , seemed to show nothing from the engine in that area, but the pipe work , would put Olly the octopus to shame , ridiculous amount of pipes ,

    At the front and they do disintegrate with age. As they are made of plastic.

    sorry, was on the school run, yeah, the elbow on mine had snapped but i didnt really notice it till i saw oil on the floor. think the pipe is about 33 quid from TPS. pretty much located dead center of the engine, at the front under the intake manifold. little ****** to get to if you got big hands ;)

    The alternator might just need a new regulator fitted...cheaper than a new alternator.

    Possible, the shop would rather fit a exchange alternator , although the engine is number -3- the alt looks to be the original fit , mr sod predicts , fitting a new reg , would not clear the fault .. and 'he is usually right

    Any way, hope springs eternal , new to me , haldex and newer rear diff + do-nut have eliminated the tesco hopp and drumming at 70 mph[ish] , new short vac hose has restored brakes , the new vac hose assy under the inlet manifold cleaned up engine response and the new 'oem re-circ valve has dispelled the odd lumpy, sometimes limited power/rpm boost , the mad chicken has flown the roost .... for now

    Things to come , id the oil leak and swap over the damaged cooling fan and alternator
