I am a fan of LPG, having owned 3 LPG cars in the past. LPG around here is available. However the costr of conversion is prohibitive and would probably cost me again what I would pay for the Omega.

I would like an Elite estate with an auto box. I reckon 1.5 to 2k to buy. Then another 1.5k-2k for the LPG. Its going to hurt the purse and I won't see the benefits for many moons.

£1700 will get me a lot of unleaded...

Around £1k I think for a DIY conversion, I'm strongly considering it on my 3.2 Elite.

However I don't really do the miles currently to justify it, filling up just twice a month on petrol. However if that situation changed and my miles went up, I would really get a benefit.

And thank you Tunnie  ;D,  with a bit of luck I,ll have mine fixed before you decide to convert yours.  :y

For the record bombing around London in my 3.2 LPG,ed Manual is ok, having a little 1.2 run around which delivers 38 plus on LPG in the same Traffic is a no brainer for me.  :y

Can you not just put the evaporator in series with the heater matrix, plumbing it in parallel sounds like a stupid approach, the water will always take the path of least resistance.

This... It is highly unlikely to be a tank issue because of the symptoms :y

So, just a bit of an update, tried Kevins idea of blocking the Heater hose to the Matrix after the LPG split, couldn't find my plastic hose clamps, but found a my hand held steel vice, clamped it in place with cable ties, idea being I could adjust the flow if needed.

Clamped in the morning when cold and have being running around like it for a couple for days now, difficult to tell on the LPG cutting back to petrol issue as I already had just under half a tank left and my local Morris hasn't had any of its 53p LPG left for a few days now, one thing I have noticed though is from cold it switches to LPG after about 400m from start up, never did that before, more like at least a mile or more in this weather.

Passed Morrisson last night, checked and yea, cheap LPG back on again (not paying BP for there 70p stuff), filled up with LPG, well almost frekin pump packed up half way trough the fill, but managed to get to about 3/4 Full and its staying on LPG all the time now.

unclamped the hose today and checked the coolant, its quiet muck'y and rusty brown, so did another flush and put some more zirks cleaner in there (some diluted Soda Crystals, Fernox and a couple of Dish Washer tablets)will let that do its job for a couple a days before another clean flush and if ready proper Coolant.

So Fingers crossed, will brim it to max with LPG tomorrow, hopefully, I believe Im getting there, will report back.  :)

Sounds like the advice to move the vap to in-line with the heater was sound; at present it's like you're trying to balance a central heating system and the water is always taking the path of least resistance (the heater) leaving the path of most resistance (vap) clogged and underperforming..

Yep, agreed. Pretty conclusive that the vap. Is not getting enough flow. Plumb it inline with the heater matrix. :y

So, Brimmed it Tuesday, not quiet there, Full Tank still gives Intermittent switch over, however having done about 50 miles next day, it started to run full time on Gas. did another Coolant Flush as still brown crap in there, seems that all this flushing and Kevins Hose block has unblocked a load of crap some where.

Another Flush yesterday, and Brimmed it again last night, so far so good, seems to be running on LPG full time now, and it was bloodly freezing last so night fingers crossed, will keep flushing till clear.

Now, one thing Ive noticed with a full tank of LPG, when parked up after driving I can hear something in the LPG Tank, best description is like a Pendulum slowly swinging and then sounds like its tapping the tank on a swing, and it squeaks, bit like a rusty barn door, will eventually slow down and stop after a few mins. Whats that?, Float Level Chamber or similar?, I though the Level thing was done on Pressure?. Anyway maybe a Red Herring.

Level is just a float arm. Sounds like that moving ;)

Ah, ok, cheers LD.

Im hoping this was just a case of crap in the Coolant Flow in the Vap or even the Heater Matrix, possibly built up in the Vap or over the Vap Temp sensor or something over time where the LPG system wasnt used for a while by the previous Owner before I fixed the Electrical problem with it and got it working again?
