It made a hole

    Hey,

    First off I'm not technical so apologies for non technical jargon. :)

    I have an 05 B7 Audi A4 2L TFSi

    Right to cut a long story short my Oil Pressure light came on and not long after my car
    stalled. AA turned up to take me home. Oil all over road but not totally drained.

    Get back and there's a hole in what I thought was the engine block, ah ...

    Get a self taught friend over who is a dab hand and we work out that its not the engine
    as such but a casing which houses what we now know the Cam Chain Tensioner (again
    excuse my technical names etc).

    The chain had gone but where the hole is we could see one of the Cogs which the chain
    should be wrapped around. Anyway ... he goes about taking things apart, first removing
    the rocker cover to asses the damage (only by sight for obvious damage) yes we accept
    there maybe more damage elsewhere but from his experience with engines he said it all
    looked ok.

    Obviously through all this and still now I'm praying she'll be ok :s

    Right .. so with that he takes off this rear housing (the bit with the hole in it) off to asses
    the damage in there (was a bit of a pain to remove but tis done now). Oh, we dropped a
    screwdriver bit through to the floor pan (which we got back) and whilst retrieving it found
    the Cam Chain, with a break in it ofc. So we take the back piece off and the Tensioner
    plastic part had shattered, in bits, lots of them. One of the cogs, the one on the left as
    you look at it, I think its the Exhaust something, has some damaged teeth.

    Right so my question is, I'm hoping and yes really really praying that I can change the
    damaged parts and all will be ok. I've feared the worst and been to hell and back a million
    times today.

    From how we see it I need, a Cam Chain Tensioner, a Cam Chain, a new Cog bit. and the
    casing this all sits in.

    It is my intention to call Audi tomz and get these bits ordered (if I can) but I'm going in
    a bit blind. I'm gonna have to call them as I'm not close to an Audi dealer at the moment
    and am car less :( but I will be as there's one near my work.

    What should I be asking for is the long and short of it

    Any help or advise would be more than helpful and I thank you in advance

    Thanks for the quick reply

    What about the metal casing? I was shocked by the hole but that chain must have been thrown out of it at some force.

    I'm thinking - what's the chances the pistons have come into contact with the valves?

    they should be ok
    as the cam belt will keep them in line hopefully
    in the kit you get the caseing and adjuster
    then chain
    but sprocket i dont know as never bought 1

    He did say something about all the 'somethings' (can't remember what word) are down when he took the rocker off which he said
    was a good sign

    But did make it clear we might still need a miracle

    if it has then its a head off job

    He checked all the Cam Belt etc and all is fine. The Cam belt was changed earlier this year.

    Oh god yeah, thats the part where I slowed right down just before it stalled. Not that I was going anywhere near fast anyway.

    Like hundreds of drawing pins in a quality street tin being shaken like a gudun

    They sound quite tappy any way don't they, was it noticeably louder before hand or was it just before it snapped that it got louder?

    Never been the quietest of engines since I've had it ... got real loud before it snapped, like you said like someone revving the balls off an older diesel

    Last pic I have, the cog which is missing a few teeth ...... You wouldn't believe how much I'm praying and potentially thankful it didn't do even more destruction

    Thanks you're a legend ... that metal casing is the bit I'm worrying about most. Oh yeah and potentially any further damage deeper down.

    Any idea what it's called?

    think its just the bell housing, I can't imagine it will be cheap, I'll see if I can price that up aswell, work for skoda, so they tend to do me well in parts

    Wouldnt it be better if you rebuild it then get a new engine? As it may happen again with the another engine.

    Out of interest, what is your engine code and at what mileage did this occur?
