I believe I have the gas leaking from the two reducers (one for each bank) into the cooling system.
One I purchased the car a little over a month ago the lpg ecu wiring still had a small amount left to do I believe the chap had upgraded it for a newer system and possibly had it running on it but took some wires off for whatever reason.
He had recently serviced both reducers himself but whether they were done right obviously is the big unknown.
Anyway I got it up and running and the map that is on it seems mostly fine, maybe slightly rough on idle I do mean slightly but since then I noticed even after sitting for 12+hours over night the coolant hoses stay pretty hard instead of returning to soft as the system cools down plus water level is tank is pushed down as soon as I release pressure when cold the it returns to the right level.
So I thought I’d remove the ecu fuse today and just run on petrol for the day and see if the coolant system stays pressurised tomorrow and even after cooling for a few hours today let alone 12+ they have gone back to soft so feel pretty confident that it’s gas leaking into it.
Not getting any visible bubbles in the tank when running off gas though maybe it’s leaking into it once off? And not actually losing coolant it seems.
Now the two reducers are what look like old Bigas ones other than them saying Bigas there is no obvious markings to suggest what model they are as it doesn’t say RI-21 on them or anything shut off valve is also separate to them so not built in.
I suppose if I could find the right parts I could service them myself but addmitdley I wouldn’t know if I’m doing it right either. I do reckon the better option would be replace but with a single vaporiser that way I don’t have all the extra coolant hoses running across the top of the intake and what not making it look at least a little neater.
Though that would definitely mean replacing the various copper lines to the reducer from shut off solenoid (currently T piece to each reducer one either side of engine bay.) though I wouldn’t even know where to begin with bending and fitting the copper pipe.
Local ish to me there I supposed to be an lpg conversion place but they never seem to pick up the phone so if they are still in business who knows.
Kinda leaves me in a catch 22 as I can’t find anywhere else nearby and I don’t know anyone personally that knows lpg. I’m not far from Coventry which is where the one I’ve been trying to contact is based. Does anyone know of any good businesses around the West Midlands? Hell I don’t mind travelling further a field of the prices are good and it’s not gonna be a place that tries saying everything needs replacing.
Hell I’d travel all the way to Norfolk or Yorkshire if necessary.
