    R reg. 1.7TD (GM) oil leak

    Hello,
    I just bought my first vauxhall ever - its an R reg astra estate with 1.7 TD gm engine.
    I noticed an oil leak and wanted to ask if its hard/ expensive to fix.
    There is oil on the engine and some parts (sorry but i am an engine retard) just below the air intake. Please see the picture for more detail (it is not my engine in the pic - just something i found online).
    I hope i was clear enough trying to explain what i mean and i also hope you guys can point me in the right direction.

    Thanks
    Mick

    Hi Mick and welcome to the forum,

    The thing you have circled in red is the diesel fuel injection pump so I'm wondering whether what you are seeing is the result of diesel leakage. Pump seals are known to fail, but there are other possible sources of leakage.

    It could be a simple as one of the diesel return tubes (or "leak-off" tubes) the cloth wrapped tubes that run between injectors at the front of the engine and one more that connects at a T-joint in the fuel line that goes from the pump back to the tank.

    I Googled "R reg" and it looks like that could be 1997 or 1998, so I guess your Astra could be an Astra F (Mk3) or an Astra G (Mk4). The Astra F had a mechanical fuel injection pump, the Astra G had an electronic pump and a variety of sensors. The one in the picture you have shown is like my old Astra F (an Mk3).

    Cheers, Paul

    its an astra F
    i hope its not the diesel pump - the engine works fine, no funny noises or anything - does that help?
    if its the pump - how hard/ expensive is that?

    I guess the first thing would be to identify the exact source of the leak. It often helps to clean everything up in the area - maybe you'll find a simple loose connection or something...

    Yeah a picture would be good. True there is stuff in the way - like that air intake thing and the top rad hose...
