Sausage Posted February 17, 2016 Report Share Posted February 17, 2016 Why not? Carbon build up or any other reason that would cause poor seating then that is the thin edge of the wedge to a burnt valve as the edge gets eaten away by the hot gases.

RainbowLaura Posted February 17, 2016 Author Report Share Posted February 17, 2016 Okay so I have a little bit more information - turns out that cylinder 1 was reading 50 and cylinder 3 was 60. The fault codes related to multiple cylinder misfire and EGR valve. So it does sound more specific than I previously thought... Quote Link to comment Share on other sites More sharing options...
wehey Posted February 17, 2016 Report Share Posted February 17, 2016 (edited) That's a very low reading and it's strange that it was driving ok before this and then suddenly went wrong. The compression is definitely ok on all other cylinders? I'm wondering if the belt has jumped a tooth?

carrera-gt Posted February 17, 2016 Report Share Posted February 17, 2016 One simple way to at least see what's going on is a leak test on the 2 low cylinders, if it's valves you should be able to hear the air escaping, if it's head gasket then bubbles in the coolant or pressure in the crankcase breather.

Pete Posted February 17, 2016 Report Share Posted February 17, 2016 I reckon it's more likely to be a timing issue than anything. I'd get that checked and as carrera says a leak test should be conclusive enough evidence to say whether it's an internal issue or not.

Sausage Posted February 18, 2016 Report Share Posted February 18, 2016 (edited) Laura what were the other two cylinders like? If they are all similar then yes i agree it is timing and your mechanic is feeling embarrassed and covering his ass because the cambelt slipped. if the other two are not similar but up around 200 then it isnt timing that is the problem. You'd really struggle to start it if they are all that low btw.... Edited February 18, 2016 by Sausage fat fingers Quote Link to comment Share on other sites More sharing options...

You'd really struggle to start it if they are all that low btw.... I thought that too. If you've got zero compression on 2 cylinders, and 60 on the other 2, would the car even start? That compression is incredibly low. If it did start, I would be very surprised if you could get it to pull off. Quote Link to comment Share on other sites More sharing options...
RainbowLaura Posted February 18, 2016 Author Report Share Posted February 18, 2016 Nope, apparently the other cylinders were fine, though I'm not sure of actual readings. Unfortunately I really need a car for work, this week has been awful and I'm so tired due to the crazy bus times I've had to get. I have therefore made the painful decision that it's time for the Lupo to go. She is up for sale and I have just paid a deposit on a lovely pre-reg Move Up! A day of mixed emotions. Obviously I have disclosed the problem, whilst emphasising all the good points, so hopefully someone fancies a project and can make her great again. Thanks for all your help and advice everyone x Quote Link to comment Share on other sites More sharing options...
Skezza Posted February 18, 2016 Report Share Posted February 18, 2016 That's a real shame Laura. If it does turn out to be a slipped belt then your mechanic has let you down. I'd have been tempted by an old KA for a few hundred pounds, just as a stop gap before fully committing. Still, good luck with your new car. Where's your loop listed?

RainbowLaura Posted February 22, 2016 Author Report Share Posted February 22, 2016 I shall probably pop back every now and then yes, although it might make me miss having a Lupo!! My husband does still have his though, which makes it all a bit easier (or harder, actually? I'm not sure yet!) Picked my Up up(!) on Saturday and have to say I am totally in love with it I have a couple of viewings on the Lupo arranged for this week, so fingers crossed. It's on Gumtree Skezza, but it sounds like Rich could've told you that!
