    A20A1 small oil leak coming from rear of motor

    As the title says. It's dripping down onto a hose of some kind (heater hose?) and my PS rack. Seems to only leak when the car's been sitting for a while after being driven. Any ideas?

    hard to say with out a picture but the distributor has an O ring seal that can leak oil out.

    Was thinking the dizzy O ring or the 2 seals behind the tbelt cover, those seem to be very common spots for both the A1 and A3 to leak oil from.

    If it is really just the rear of the engine...towards the firewall. The oil filter housing has a figure 8 O ring that can go bad.

    Alright, I'll keep that in mind as well.

    Don't forget about all the PCV hardware back there that develops leaks.

    Check the oil pressure switch.

    Thanks for the tips, ever since I had a new pan/pan gasket put on the car the leak has become really tiny. It was a lot worse before then. BTW is synth blend oil bad for these cars? Paranoid that it's going to gum my motor up or make it leak even more oil.
