Before I forget here's the pictures of your thermostat.

[Robski]

Proved the thermostat was working properly though tonight, and if the cylinder head was cracked your car would run terrible on petrol too...

He is a first class knobhead Rob

I feel like jumping all over the weasley little tw*t but as Ive been told by her indoors its not the way to go,so take the proper route to start with

[Lazydocker]

  Unfortunately I'm on my mobile so quoting and highlighting is a bit of a pain but I'll try to give some opinions...

Firstly, as you probably know, LPG needs a stronger spark than petrol to ignite so the HT system needs to be in top condition. That said, it is a common excuse used by the "professional" installer when a system isn't running properly!

As for the coolant system pressurizing... Of course it is, it's a rather pressurized system!

I would suggest you get onto Trading Standards first thing, before anyone touches anything on the LPG system! It sounds to me like you've got him under the sale of goods act as the system isn't working. Another thing, which TS may suggest, is contacting the kit supplier and having their engineer inspect the installation. The solution which will most likely be suggested is to have the whole system removed and the car made good (as much as possible) and you get a full  refund! This may be the best option as you could then put your money into a DIY kit from the supplier we use, which is proven to work on the Miggy, and you'll end up saving yourself some money too.

it sounds like this so called lpg installer is ripping him off .go to the trading standards and also find out if he is a lpga registered conversion specialist he should be registered with a proper certificate to install lpg .trading standards will look into that for you .he needs an installation sticking up is arse and ignighting .if you go onto the calor website that tells you about installers and the guidelines they have to go by good look guys

Unfortunately he doesn't need to be LPGA registered to install LPG kits to cars

And as for going to the LPGA.... I wouldn't bother. They're more interested in getting the money from people registering than actually regulating fitters

Interestingly though... I don't reckon that Thermostat housing's been off :-/ :-/ :-/ Bit hard to tell from the pictures but.......

It does look like the thermostat has been off you may just be able to see the black sealer under the thermostat housing, sealer is oozing out from where the transfer pipe goes into the thermostat housing too. I dont think that he has replaced the thermostat though which he want £180 for doing

Shouldn't have sealant on the transfer pipe to thermostat housing joint, there's two O rings on the pipe and a dab of vaseline is all that's required to help the transfer pipe to sit fully home.

break me... Was he wearing a striped suit and a mask?

I have just had a phone call from Rob, who is at the Independant Gas Fitter's. He says there is a miss yet again on both Petrol & Gas it is more noticeable on gas. Gas Fitter says through experiance that none genuine Dispacks dont produce a good enough spark...
Yet last night again the car was not missing at all and yet today it is....
The Gas Fitter also said that the gas mixture is right!

[Lazydocker]

I know this is a long shot but... Is it worth substituting the dis pack for a "known good" one just to try? :-/ :-/ :-/

The fact that it's more noticeable on LPG does fit with a weakness in the HT side.

It seems strange that this intermittent misfire keeps coming back.

To put you in the picture.
Rob went to the York Meet where his spark was checked with a tool Mark DTM had. Each lead was firing 40,000 volts, that was with a know good Vauxhall Dispack on that, Rob had off me. But the car when on tick over was running rough, yet when he was coming up the motorway he was going 80mph with no problems. So it was said that there must be an airleak. Pete stripped the car and found that the bottom inlet plate had loads of bathroom sealer all around the gasket, which had actually reacted to the gasket. No-one had a spare so it had to have cam cover sealer on until Rob could get a new gasket from Vauxhall.
Rob stripped the car down and put some different sealer on as he needed the car for work, then it started to rain so went in leaving the scuttle panel off. When he had put the car all back together it was still the same.
So he got a new seal from Vauxhall. We went up to fit it. Rob was saying he wanted a new dispack and leads as he thought water would have got into the dispack. I did not think so as the leads go over the dispack. Anyway Rob bought a new dispack off ebay which we fitted and the leads to start the car which made no difference what so ever.

Right... So reading this there was nothing noticeably wrong with the first Dispack, Rob just chanced it as a precaution :question :question In fact, it was tested OK by MDTM at York but the car was still missing. Petrol and gas or just Petrol?

Are there any codes coming up now when it's missing?

I'm just wandering if Rob has been unlucky and got a faulty plug which keeps breaking down... Not unheard of for a brand new item to be faulty and, sorry to repeat myself (!), if there is any fault whatsoever on the HT side it will become much more apparent when running LPG as it needs more oomph to burn :-/ :-/

That said, I wouldn't encourage random part replacement as it just introduces a load of unknowns

[Robski]

Right just got back from independent gas installer,the install is correct although looks like a schoolboy install,whilst with this installer the car appeard to miss on both petrol and gas more prominent on gas.
On petrol intergrators read
1) 150 average
2) 128 average
On gas intergrators read
1) 130 average
2) 110 average
He concluded that the gas was right but car appears to have a ignition fault.
We have changed numerous thing numerous times,anyone got any advice?

Yep... Those figures seem reasonable

Right, I've been bouncing ideas towards LK whilst you were at the fitters so check through some of the posts above and we'll see what we can work out

At least you have some good news, in that the LPG figures seem about right. Now it's just a case of starting from basics and working through

Did you have your old Dispack on after replacing the inlet manifold leak? If not then I'd say first port of call should be to revert to a "known good" Dispack (the one from Daz which was tested at York) and start from there. The fact it's missing on both fuels but more on LPG does point me towards an HT Fault

Yes the old Dis pack was on after repairing the inlet leak but it was still playing up,which gave me the thought of the rain maybe got to it when scuttle was off,which is why I bought a aftermarket Dis and leads.LK and Captain Zok got it running right on petrol last night no missing or anything,but would not run on gas.I went to this independent installer this morning on petrol as the gas was not working last night so never bothered trying it,he turned the gas on and it was running but missing.The car has Vectra cam covers on(not good I know)and as you look into the plug wells the plugs seem to be offset,could it be that the HT leads are not sit on the plugs right,therefore not giving a full strength spark? just a thought
