    Hi guys, does anyone know what this part is (circled in red)?
    Popped up my mates unit to have a look at my car last night and noticed a patch of oil on the ground, turns out i have quite a steady drip coming from the under side of this part. It is a little releiving because i thought my car was burning oil at quite a rate, but it's just leaking instead.... It looks like the cap comes off the front of the engine so hopefully i can just replace the seal. oil leak.jpg

    Should have the parts sticker on the front of it.

    This is good info, now I know what that is - mine is still nice and dry! (I never considered where the servo would get its vac from in this setup)

    Mines got quite a decent leak going on from there! A bit of a relief to be honest, I thought the car was burning quite a bit...
    Apparently it's a o-seal inside the pump that lets go. I'm going to take the end cap off and give it a go with a thin smear of red high temp silicone
