    Cam belt failure!

    What a disaster this week has turned into. First off split up with my wife and yesterday my cam belt snapped (waiting for the third).
    Its being looked at properly on Monday, but the first opinion was that the key has sheared from the back of the bottom pulley. Will wait to see how much damage has been done.
    What shocked me was the way it happened - not what I expected.
    Started up fine, drove a couple of mins, stopped at traffic lights and the engine was a bit lumpy on tick over. Pulled away from traffic lights and engine cut out. Trying to start it again just sounded like the starter motor wasn't engaging. No metallic noises at all.
    Depends what the damage is, but any ideas what this is going to cost?
    Garage said roughly 800, but hard to estimate yet.

    Unfortunately once the cambelt goes repairs costs are steep. I think 800 sounds reasonable considering that a former colleague of mine paid well over a grand to repair his damaged 4cyl Omega.

    if you do rebuild due to bent rods and piston i would upgrade them if you are planning to mod her. Sorry to here about the other half take it you did not want to break up.

    I'd be inclined to say the pistons rods and the rest of the bottom end will be fine, head and valves will be toast

    you have to weigh up the options, you can drop in another engine complete, but you then dont know its real history etc. or you can fix the engine you have for roughly the same money.

    a head rebuild with new guides and valves will likely stretch to around 600-800quid as suggested, but it might be an idea to buy a good used head (probably 2-300quid?) and work that over with new stem seals and relap the valves. You can also then inspect the bores etc when the engines apart to see if they need work.

    Depending on how much of it you can do yourself you could have it back up and running for under 500quid, but expect to pay a lot more if your not doing it yourself.

    highly unlikely you will do bottom end damage at those revs. you will have done exhaust valves on cyl 2 and 3 if I recall.
    what mileage have you done? might be an easier option to just pick up a second hand engine, you may even be able to flog the old engine to someone with some spanners for a buildup project

    Pistons will most likely be ok, i would get a used head and whack it on there, its what i did when my bottom pulley gave in,cost me under 250 for the head, gaskets, bolts, pulley and belt kit

    Just had a call from the garage - not good news.
    It is the key that sheared off, but as it had been getting progressivly worse it has damaged the crankshaft. Majority of the vlaves bent as well.
    The garage suspect it wasnt torqued correctly and lockthreaded when it was replaced (before I bought the car).
    So, it seems a replacement engine is the only option. Any tips on finding a good one? Its a 1.8T APU on there at them moment.
    There is one on eBay for 750 with around 75K on it.

    there is an apu engine from an A6 on ebay too for 100 iirc


    what about an AEB engine, then just use your sump and inlet manifold on it

    gutted for you stringster , i had exactly the same thing happen to my 1.8 non-turbo, key sheared, head was in a right old mess, had it rebuilt and got 20 quid change from a grand !

    runs like a dream now though

    depends what you can get , but for me it ended up being the best option, best price i could get for a second hand engine was around the 600 mark, by the time i got a price for fitting, and making it good, i was way over what it cost to rebuild.

    if the 800 quoted is still valid for a rebuild i would say thats a cracking price.

    Unfortunately as I have lost my drive and garage I'm unable to do any work myself (and no it wasnt my choice - caught the ***** with someone. However I loose my house, kids, money and now car (sorry about the rant)).
    I have to way up the value of the car and the cost of the new engine and fitting. I would like to keep the car but wouldnt spend more than 1500 on it.
    Anyone seen the Audi rebuilt engines from the US on eBay? Seem to be able to get them for around 1000.

    Thanks for the offer - got some family in Cwm so visit South Wales every now and then.
    Seems to be only one engine on eBay with 70k on it for 750 plus 50 postage.
    I am very tempted by the Audi re-manufactured one from the US for just over 1k. Just asked them for shipping costs.

    You cant have searched very hard:

    http://cgi.ebay.co.uk/Vag-1-8t-Apu-e...QQcmdZViewItem

    http://cgi.ebay.co.uk/AUDI-A3-1-8T-E...QQcmdZViewItem

    Theres more on there, a few being FWD variants from golfs/A3's however i think that you can swap enough parts around from the engine you already have to make it run.

    There are also 4 or 5 A4's breaking and they may well have engines available...

    i searched for "1.8T engine" btw just incase you wanted to look for yourself.

    Hmm, seems good, not sure what the adapter to manual is though? As the cranks are different manual to auto

    Need to sort it out soon so I've got it down to two options at the moment:
    1 - replacement engine - 70k with 3 month warranty for 500, plus fitting for 500.
    2 - rebuild - company in Cardiff will collect the car, rebuild engine and drop off for 1000 total.
    Both come out around the same price so now I need to decide the best option...
    Any opinions?

    imo i'd go for the rebuild.

    The simple fact is that if the engines coming apart it means that its been checked over. depending how much they change (ie if they do bearings/hone/rings etc as well as the head) you will end up with an engine thats as good as new instead of one thats done 70k which is a better deal.

    however at 1000 i'd be querying exactly what they are changing before i would decide.

    Good point. I'll call them and query a bit more. They seemed obsessed by the oil pump to start with. If the turbo has gone they will replace for 350 as well.

    If the cost is the same, then rebuild. When i blew mine i had a quote from someone for 1200 inc fitting and warrenty, and then some of them were quoting 2k plus vat, i bought a used engine for 500 that had the oil pump changed already as well as the cambelt kit, and i was lucky enough to be able to do the work myself.

    Good luck with it, and the driveway offer still stands

    if they're talking about the oil pump then i guess they're at least looking at the bottom end. You will probably find that even if that price doesnt include rings and shells it probably wont cost that much more to do the rings and shells once the engine is out and in bits anyway.

    Why would you suspect the turbo has gone? It was only a timing belt slip? If it had happened at full boost at 6krpm and shattered valves etc ended up making their way into the turbo then fair enough, or if it had suffered a thermal meltdown due to bad fuelling or too much boost etc. But a snapped belt under little load at no revs shouldn't have damaged the turbo in any way.

    try www.theengineshop.info

    they rebuild engine for 1295 inc vat i think, and will undertake fitting.

    i have one of their powerplus engines after i bought a car with cambelt failure, put a second hand engine in, only for the same thing that has happened to you 26 miles later! so think before getting second hand engine as i wasted 700 and a lot of elbow grease!

    hope your luck turns, i've been having a lot of bad luck recently but not quite like yours.
