    2.5tdi oil leak around alternator

    Hi everyone, yesterday I bought a 2003 a4 2.5tdi quattro with a oil leak that seems to be coming from behind or above the alternator which is covered in oil.
    anyone know where the leak is likely to be coming from ?

    Any advice on being able to stop the leak or finding it without taking the front end of the car off ?
    Might try some of that engine stop leak fluid.

    no, I have read that it could be a camshaft seal when the alternator is covered in oil.

    Yeah, more than likely your cam seal - mines doing the same.

    I would never dream of using it to be honest. From what I have heard it can block small oil channels, clog oil pick-ups.etc
    Which can lead to bigger problems.

    As above, it's great in a cheap old banger but not in a Audi. It can cause blockages. All it does is thicken up the oil and soften the seals. It's not a permanent repair.

    Same with Radweld.....fix the leak properly rather than boding it!

    Yeah, but when mixed with oil it thickens up.

    There are loads of very small oil channels - especially around the hydraulic lifters, if oil flow is reduced even slightly below spec it can cause accelerated wear.

    As Dan said, its fine for a banger you don't care much about, but modern engines run low tolerances - so even thickening the oil slightly could be devastating.

    My cam oil seal is weeping oil too - as I have exactly the same symptoms - im holding off til the cambelt needs doing again, unless it kills another alternator.
