hi, cars driving me mad, when going to accelerate i get a pink and then it goes away, now i had the cambelt changed and the cam gaskets changed by VX. Vx managed to break the 6 plug lead leaving me with a misfire on the way home. Changed leads and plugs while i was at it. Ive had a hissing from the plenum checked everything reseated the plenum with new orings, done the breathers got all new orings including the odd shaped one, cant find no vacuum leaks anywhere. Did a paperclip test go a code 19, changed crank sensor, which ive now found is not a Vx part, but has Siemens france stamped in it like the original. Car has been idling ok. not great performance, still getting a code 19?. then EML light comes on got a O2 sensor fault, changed that. checked codes today, only code left is the code 19!!. What i dont know is the sensor just a bad made part even though it has all the same markings and would this cause the pinking.Also i think the knock sensor wire is trapped between the head and the cam cover, VX again... sorry for the essay

another example of hoodie vx workmanship. Knock sensor wire is a favourite for getting trapped or so i have read. Could well be the cause, but a more experienced owner will help no doubt.
If you dont mine me asking, how much did they charge you for buggering up your car? What ever it was id be taking it back for some money back. Dont let them near it again imho. Muppets.

hi,  the advice on here is to use genuine gm parts due to early failure of pattern parts.  I bet the vx damaged the cable to crank sensor or possibly dislodged the connector at back of plenum when changing gaskets.  :-/

hi, Vx charged £340 to do the cam covers, i also had them do the cam belt which cost £360, what i noticed when they did that was the mount that hold the secondary air injection pipe at the front, they didnt undo it they just hacksawed through the rubber mount and left it. But what im wondering could it be a failing dis pack through all in the plug wells and Vx damaging the HT lead, or not the original crank sensor , or the trapped knock sensor wire, what would be the first thing to look at?  Oh also when they did the cam covers they must of took the scuttle away as the rubber strip that runs along the edge of the screen and is held down by clips is all loose and 3 clips missing!!

aw, what a mess, sorry to hear about your further problems. First off, did they clean the breather system, the cause of the failed cam cover gaskits? If not they will just blow again. Guide in maintenance section.
2 if oil in wells then likely the plug leads have had it anyway as the oil attacks the rubber with the heat from the engine. Cheapo jobs can be had from eurocar parts fro 35quid, but they are not numbered and are not the correct length for the omega but they will do. Vx want 120 a side iirc.
3 if the leads have been changed and still miss firing then change the plugs. If still no good then that only leaves the dis pac. Some breakers on here can help for reasonable money.
4 i dont have first hand experience of the knock sensor wire/issue but obviously un trap it and check for damage to the wire.
5 i would be taking pictures of the bad workmanship from vx and making a case for compensation. Breaking stuff on you car is one thing but hack sawing bits off is just vandalism. Maybe check the scuttle is not broken or cracked as they probably did not know about the clips and just pulling on it can break the plastic around the wiper hole. Also insure the rubber is still glued to the bottom of the windscreen and that no water can get in as this can bugger the wiper mechanism and leak on the dis pac etc.
6 crank sensor code should go after a phew trouble free starts(30 should be enough) but you may prefer to just fit a genuine vx item as its not safe to drive  with a bad sensor. The engine could well cut out at random and leaves you with no power assisted stearing or brakes.
 Let us know how you get on, there is not much that gets peoples attention on here more than crap dealer service. Although they are all a bit quiet so far it has to be said...maybe theyll be along shortly.
See how you go with that and dont be shy to keep your thread updated. Best of luck with it, as you dont sound like youve had any so far. Ttfn.

Ps cam cover bolts should be 8nm meters, no more, and can come loose when the rubber orings retract a bit. Wont hurt to check them now and keep an eye on them later.

Thanks for ur reply Chris, its been since ive got it back from Vx all the trouble started. I may have to get a geniune Vx crank sensor to be on the safe side, just wondering if anything else will stop the code form going, its been started far more than 30 times. I used to do all my own mechanical work, but i used my dads front for that, but he has since gone into residential care, so had to go to VX also needed the car to visit him. I changed plug couple of weeks back for bosch super 4s and new leads from Ebay which were actually the correct lengths. Just cant seem to get rid of this pinking, like u say could be the dis pack as i dont know how long the leads were bathed in oil and then VX screwing the ht lead up causing it to arc.

if your going to change the crank sensor anyway, see if that cures it before going any further.
