    Hi,

    I am looking to get my 1991 205 1.9 GTI back on the road after 8 months, but
    unfortunately it failed its MOT... the first thing it failed on was that the
    rear bump stops were non existent... I don't think they have been since I
    bought the car 5 years ago to be honest... I asked another test centre if
    they were required and he could not find any reference to them in his guide
    book, so told me they shouldn't be a problem... is this correct???

    Secondly (and I think more seriously), once the car has warmed up it
    smokes... the emissions tests were fine, but the tester said it was blue and
    failed it!!! :-(. Does anyone have any idea what might be causing this, I
    am hoping it isn't piston/cylinder wear, but I am not holding my breath!

    If this is the case, what would be the easiest/cheapest resolution... I'm
    not much of a mechanic, but I don't want to be stung on an expensive
    rebuild, or engine swap unnecessarily!

    Any help would be greatly appreciated.

    Steve

    Yep, I'd look at the valve stem seals first, although I heard these were
    mainly a problem on the 405 rather than the 205.

    Funny that the tester failed it because the smoke 'looked blue' - I didn't
    think you could be failed on the colour of your smoke?!?!? If it passed the
    emissions test, I thought that'd be it...

    Hmmm...

    Chris.

    Does not valve stem seals a "frequent" failure on that engine ?
    Also, if not started for a long time, perhaps piston rings may simply be
    stuck.

    It would have to be "excessive" and it pretty much puts the onus on
    the tester. I am an MOT tester and in the many years I have been doing
    it, I have failed a car once (VW Golf) on excessive smoke. It was
    really bad, and it ended up with a new engine. It was completely
    knackered.
    90% of the time, on XU5 or XU9 engines it is the valve stem oil seals
    no matter what car it is fitted in. (205, 309, 405) They just go hard.
    The rest of the time it is also piston rings/bores.

  5. If the smoking is worst after a longish period of idling it will be valve
    stem seals, in which case it should more or less clear after a while under
    load. If the smoking is worst while the engine is working fairly hard, it's
    rings.

    One more thing, get your MOT done somewhere else.

    Thanks for that... it is much worse after a few minutes idling and does
    clear fairly quickly. Sounds like the valve sten seals... In which case,
    how big a job is it??? is it something i could do myself, or do i need to
    get them replaced professionally... any idea of costs???

    If its been sat for a while then its quite likely to be the valve stem
    seals. Quite common on these engines (both petrol and diesel variations).
    Basically you'd have to take the head off, replace them and put it all back
    together, so not something for a novice mechanic. You'd also do the head
    gasket and cambelt at the same time (which would add a bit more to the
    price).
    Of course, might be an idea to get a compression test done first. Then if
    it is the rings you may as well just get a new engine as they can be picked
    up fairly cheap.

    You can do the stem seals without taking the head off if you have the
    tools - compressor and appropriate connection to screw into the spark hole
    to pressurise the cyl. Then you need to whip off the springs but I cant
    remember the tools for that - normal spring compressors require the head off
    but you can get them that grip the head instead, and the compressor holds
    the valve in place. Its best to reseat the valve anyway so get the head off.
    IMO a head recon is one of the easiest jobs i did on my 205.

    My 309 GTi (1990) Same engine was sat in a damp garage for 2 years before I
    got hold of it, after an oil spark plug change, new HT leads, Rotor Arm,
    Dizzy Cap change and a little fresh fuel fill up, after 30 seconds of
    turning the engine over without the plugs in to clear any crap and rust out
    I replaced everything and it starded, first time really... took it for its
    MOT, failed on a couple of bits, nothing serious the Tester said it was a
    bit smoky, but still passed the emmisions test, so after replacing the worn
    parts, normal CV boots and stuff I put some injection cleaner in, took the
    car to a private road, used all the fuel in the tank, then put some more in
    and gave it a good old thrash for half an hour, result, no smoke. Took back
    to the Testing station and it passed. Wahey !
