    Default Useful info for 1.9 16v CDTi owners

    Guys,

    I'd like to link to this so it gets a bit of exposure:

    http://www.vectra-c.com/forum/showth...=160217&page=4

    I think it's important that 1.9 16v CDTi owners are aware that if they have timing issues or water pump seizes... or the belt snaps etc.. that actually the engine may be able to be revived with a relatively inexpensive fix.

    If it helps one person then it has done its job.

    Cheers.

    And I can't understand what dealer would tell you that it doesn't need replaced.

    My dealer keeps equal numbers of water pumps and timing belt kits in stock

    yup do the water pump.

    as a massive coincidence today, the taxi driver that picked me up to take me to the dealers to pick my car up was driving a veccy cdti 150! So I started chatting to him about mine and as soon as I mentioned the tensioner failure he said "broke the rockers did it?"

    i was a bit stunned! then he said. "my water pump seized at 55k. belt sheared and it broke nearly all the rockers. about 60k later the cambelt snapped and broke them again."

    so his veccy has had belt related failure TWICE and neither time has resulted in serious engine damage except to the rockers! he now on nearly 200k.

    so - that's a bizarre coincidence, but a valuable bit of info for sure!

    i have massively restored confidence in my motor now, which incidently is running spot on again.

    Thanks for posting this. Makes me feel a bit better about my Vec. I changed its cambelt (first time I've ever done one) and worried about it ever since. I guess it would depend how fast engine was turning how much damage was done? Ie more on a motorway than pulling into a car park?

    Well this is what I thought, but if you check out the link I posted at the start of this thread, there are a couple of links inside it to other forums. One of them states motorway speed failure - so that would have been worse case sceanrio. However, rockers replaced and everything was running fine again. I don't actually think it matters on the speed. The pistons gives the valves a whack and the rocker breaks which allows the valve to best efforts retreat to the closed position and therefore they stay out of the way after that. I had no compression on 2 cylinders and little on the remainder, so the valves can't have been fully closed but they are clearly ok now! Done about 150 miles since the rockers were replaced and it's running fine. In fact the caterman is going back on it today - I'm missing the extra 50 horses already!

    £650 all in - main dealer. The actual rockers are cheap as chips so it makes sense to get all 16 done just in case any of the remainder are stressed or fractured.

    1.9 CDTi 150 Part numbers in case they help anyone who wants to DIY:

    P/N: 93197114 - rocker arm £5.70 (16 = £91.20)
    P/N: 93178683 - B6D2 seal ring £0.56 (4 = £2.24) <- injector seals
    P/N: 93191278 - engine timing £117.00 (1)
    P/N: 93178481 - gasket £8.40 (1) <- rocker cover gasket
    P/N: 55568637 - pump, water £58 (1)
