LPG is "harder" to ignite than petrol ... so any slight problems with the HT side can show up on LPG but not on Petrol.

Not saying it is the HT side .. just don't ignore it as it seems ok on petrol.

[Kevin Wood]

Just re-read and if the Gas install is that new it's worth taking it back to them. They will probably claim it's the other garage's fault and start arguing the toss but if it runs perfectly on petrol there is little for them to argue about TBH.

Cheers Kevin I will be going back tomorrow mate, me not been mechanically minded thought when I put it in with a registered installer and paying just short of 2k it would be done properly but I now know otherwise.What sort of idiot drills through the top breathers and plenum to attach the gas rail?.

[Marks DTM Calib]

Anyone?

What do you want, moon on a stick!

I told you how to sort the issue on petrol  

And the issue is sorted on Petrol   have you not read

I seem to recall that the car was taken back to the LPG installer after the cam cover change?

If so, whats the betting they messed with the lpg settings?

And now the vac leak is all sorted.....the lpg settings will be out!

Cheers entwood but brand new bosch ht leads 400 mls max  
Going for more on the lines bad install now.

[Darth Loo-knee]

This is why you are The Master  

I really hope this is the case and they sort it out for him.

Hi Mark got to go down them lines now mate,but still not happy they drilled through the plenum and top breathers to mount the gas rail,but when you pay just short 2k to a registered installer you'd expect it done right(which I thought it was until daz seen it and thought it was a diy job,think daz sent you a pic of it on friday).Topped gearbox up yesterday as you told daz and its back running sweet again on petrol

Yes, the photo is here.



The theory behind the auto box level is that because the auto box breather has been connected to the engine breather setup then the auto box will have been held at a vaccum.

The box is not designed to work under vaccum so any oil vapour (likely to be quite a bit) which would normlay have simply condensed and fallen back into the sump, will not get drawn into the combustion porcess and burnt.

The result is a drop in auto box oil level (was it down much?) which gives rough changes and can (if low enough) result in additonal drag from the torque converter at idle.

how well does the engine run on DexIII fumes?

Well in this case, not to well.

But that might also be due to the fact that the small breather was left dangling resulting in an air leak!

Hmm. He's clearly watched the Reg Prescott guide to fuel rail mounting.

It would appear that the LPG guy this morning has said its miss firing when on gas on no3 cylinder.....

....what I cant work out, is how he knows that!

It has new plugs and leads plus a known good DIS pack fitted (DIS pack would affect 2 cylinders though)

The system I have allows you to switch over one cylinder at a time for diagnosis.

Maybe there's some crud in No. 3 gas injector. He seems the type who might have cut the hoses with a hacksaw, thus ensuring plenty of dust ends up in the system.

Hi all,Mark regarding the gearbox approx a litre and half top up,then sunday got automatic gearbox on display and all the orange lights came on at gear selector,so turned engine off then restarted and moved gear selector through all gears several times,not had automatic gearbox on display since so I assume it was the ecu catching up now the gearbox can breath,as for running on dexron3 it does not compare to petrol or gas.

Hi Kevin the gas fitter connected to laptop and told me he was shutting each injector down individually to diagnose  the fault,but could of been filling me with crap for all I know(thats why Im a plasterer and not a mechanic)But rang Daz (loo-knee) and got this fitter to talk to him about his diagnoses,so back to Dazs tomorrow to try and rectifie the fault.
