This is the official thread for the DIY LPG conversion on my new Omega 2.0.

Please can I seriously request, that while anyone is welcome to post in this thread, can we keep the topic strictly focused on the subject. Off topic posts will be deleted by Admins, possibly with other consequences

The plan

I have bought a scrap 2.0 16v Omega, with an OMVL sequential gas conversion on it. The plan is, to remove this conversion, and make a really good job of installing it on the new Omega. And then get it certified.

We will be using some OOF teamwork and working together on this one.

Martin Imber, our resident DIY LPG guru, is local to me and has kindly offered to lend a hand with the conversion and pass on his knowledge. My electrician friend Markie will be involved, and hopefully Tunnie will be joining us, dependant on time constraints.

We will be doing this over a couple or more weekends - whatever is required to make a thorough job.

The car will be kept "mobile" at all times, so it can be moved wherever it needs to be.

This thread will be updated with our progress, and of course plenty of pictures.

Today, due to being well and truly snowed in - after carefully studying the wiring diagram Martin found me for this LPG installation, Markie and I decided to get to work and remove some LPG components!

We have made some good progress. The tank has been removed, as has the front end LPG loom, ECU, vaporisor, changeover switch, Coolant hoses and T peices, inlet manifold with the LPG injectors, vaccum thing (!), LPG hoses etc.

Very few wires were cut, but those that were, we are confident of what they are and where they need to go.

Everything removed has been photographed or labelled, and has been sucesfully referenced against the wiring/installation diagram Martin sent me.

It's not completely done, there is one blue wire we need to follow from the engine bay to the back, but we know where on the loom it belongs, so it's OK. Also need to remove the supporting bars in the boot, for the LPG tank.

Photo's to appear below in a tick...

Slowly being stripped...



The ECU



Vapouriser



Inlet manifold with injectors







Gas tank!





Loom on it's way out...



Connections on tank..



Connections to vapourisor



Wires being identified..



LPG kit anyone?!





The working conditions!

Well that is a very good start.

I reckon it will almost fall on to the new car

I wasn't intending on doing anything today, but being snowed in here all day, what better to do!!

I must admit there were a couple of dubious looking connections, which will have to be much improved when refitted.

I'm pleased you think it will work well! On the basis that I wasn't able to test this LPG kit out on it's old car, what do you think are the chances something major won't work?

Looking at the way it was fitted, it all seemed a bit "precarious".. I'm no expert, but I cannot see it being done by Avon Autogas like that..

The RPM wire you mention, is attached to one of the DIS wires.

Coil feed then!

You reckon it looked a bit sloppy as well.

At least it can go on a bit neater.

How was the evaporator feed organised, also get all that plumbing including the T pieces

T peices not a problem

Not 100% sure what you mean, but, there is a 6mm pipe coming from the tank into the engine bay, into the vaporiser (I think?)

From here, there is a thicker pipe that goes over the rocker cover, which is the liquid lpg feed to the injectors??

[JamesV6CDX]

70 Litre LPG tank. Apparently will only fill to 80% of capacity, which means it should hold 56 litres.

Which means at 43.9p a litre, it will cost £24.58 to fill. At 28mpg, this will cover 344 miles. Works out at 7p a mile.

As you pointed out some suspect connections there need to be improved. Is there anyway of testing some of the core components out of the engine?

I doubt it,

To be honest, this is a lot simpler than the old mixer LPG systems. The only real front end components, are the Vapouriser, the ECU and a load of wires that need to be attached to the cars loom.

So not a lot mechanically to go wrong, that I can see.

Hopefully it will all "fall on the new car" as Martin thinks

Plumbing - the water pipes to and from the evaporator

Mind you have you found the gas main route?

By gas main route, do you mean the pipe from Tank to engine bay? If so, then no.. as the ground was covered in snow and I was too chicken to get under the car

I would say that moving this system over would be one of the easiest LPG things to do

Not as far as I know - if it doesn't work yet all tests OK - off to a specialist
