Omega General Help / NOT hg, but..
« on: 10 February 2011, 09:33:13 »
Hi again, thanks for previous help, much appreciated. Can't be HG as system not pressurising too much, no mayo on dip (though there is a little at the top of the filler).
Is there a cure for what appears to be plain, fresh water gathering in the nearside head around the plugs? Would this cause a misfire (cutting out!) on lpg when first transferring from petrol? After topping up coolant yesterday to too high ( left cap off to allow any air in system to bubble out) then going out for a run, got heating back but it took about 6 miles (mostly uphill) to get running with only slight misfire on lpg. After a short stop, (10 minutes at most) transferred onto gas very quickly and ran beautifully, though still a little rough at tickover. Bearing in mind my lack of facilities, skill, knowledge, tools etc. are there any recommendations where I can take the car to get all this fixed, preferably in Fife and NOT Wellside Motors? (I know they're Perth & Kinross but they're still nearest lpg specialist I know of). Thanks for any help, will be back at pc by 13:00.

LPG is Zavoli multipoint, service carried out about 6,000 miles ago. Oil is clean. Servicing has been carried out by a mechanic friend of previous owner, as was head, cambelt etc., so no actual dates/mileages available.
Will check maintenance section for "paperclip test". Sounds fascinating...(just showing off my lack of knowledge, presently I have no idea what I'm about to find out)

Re the smell - new tailpipe fitted the morning I got the car. It does smell a bit like "new exhaust"! Did I mention technical ignorance?

Thanks guys - this really is an active forum!
There is a slight unevenness on (petrol) tickover- again, Wellside reckoned this was due to one cylinder being poisoned by water ingress. It seems to run perfectly on petrol, even the lpg eventually runs almost ok (very rough at tickover, mind)
Been in touch with the previous owner (who phoned me back as he was unavailable for my call) who says he doesn't understand why I've had the problem as he's been all over with the car since the heads were skimmed and gaskets, cambelt, water pump, oil pump etc replaced not that long ago. The car is sitting at 97,000 miles which I know is nothing for these motors. There is an acrid smell as it warms up, which never gets too bad and does vanish at normal operating temperatures. Doesn't smell particularly of exhaust, though.

Thanks for the very quick reply - I took the car out to Wellside Motors as (apart from a loss of heat in the car) the main symptom is a misfire when on gas and as they're the local lpg conversion people they seemed a good place to start.
There is a repeating airlock which is released when the header tank cap is opened. There are air bubbles apparent when the engine is revved a little, also there seems to be at least one cylinder not firing correctly which is noticeable at tickover.
The problem is actually their diagnosis, I was hoping for something much easier. They didn't want to even talk about fixing it as they said it would cost more than the car is worth. There seems to be no loss of power in normal driving, there's no water visible in the oil, the coolant system does not seem to be pressurizing as much as I would expect (even though I am almost completely ignorant re mechanical things) as I have had 2 motors previously with head gasket problems!
Hope this info helps. Wellside did say they had converted one Omega previously and swore they would never do another one, so maybe they just don't like 'em?

Major request for help here. Having just bought a W plate 2.5 auto with a 2006 lpg conversion which was perfect (for 11 years old) I now find 400 miles later that it has either/or the problems in the subject line. The motorway journey from Cheshire to Fife did it in!
I would rather keep the car than sell it on (it IS that good) but as I have no technical knowledge or ability, or anywhere to use as a workshop, nor the right tools to carry out anything other than really basic fastening/unfastening, I hope somebody can direct me to a reliable and relatively inexpensive repair shop somewhere near Glenrothes, Fife. PLEASE!!

Hi, just bought my 2nd Omega (Miggy? mmm...), a 2.5 with an lpg conversion. Sourced on ebay, perfect when seen, (as new tyres, new tailpipe, clean, cambelt and head gasket done 6.000 miles ago etc) went like stink, drove home from Wilmslow, Cheshire, and my next post will be in the HELP section!
Nice to be here, I like Vauxhalls generally, my real joy being a 1965 Viva (called Flossie) which the Miggy (mmm....) was intended to replace for the rest of the winter. Flossie may well have to come back out. Unless major advice/assistance can be offered here.
