Omega General Help / Re: Loosing coolant

« on: 07 March 2024, 10:10:49 »

Carefully check the plastic parts of the main rad for leaks as well.  IME, you won't see a puddle under the car, and probably won't see much in way of steam either.  Its hairline cracks that close when the pressure drops.

I had a spare cap with a shrader valve in, and pumped up to about 8PSI, then used a torch to locate mine.

Omega General Help / Re: Problems with LTFT on LPG

« on: 07 March 2024, 10:07:06 »

Don't rule out injectors getting tired.  Many brands dont last as long as petrol/diesel injectors.

My last Omega, the injectors were worn after about 40k miles, with the symptom being lumpy idle, partucularly when cold, leading to occasional stalling.  In my case, rather than replace injectors, I just had it switching back to petrol under 1200 rpm and not switching back to gas until 1600rpm.  Had I known how long we were going to be keeping it for - the lack of LPG in my area made it unviable, but we kept on being able to get LPG on various journeys - I would have replaced the injectors.

The fact that it sounds like yours is over fuelling when pushed, and under fuelling at light loads, that does sound like mapping isn't right, or that the evap isn't getting the heat at lower loads.


In the UK, our LPG is mostly propane with a small amount of butane IIRC, presumably to stop the propane from freezing when cold.  I'm guessing this mix was always the same, as I never had to remap mine in that latter years based on time of year.

IIRC, over half of the ATF is retained in the torque converter. So you will only drain c.3.5 litres of oil first go.
So....in my understanding....first oil change gives a 50% ratio of old to new, second one gives you 75%, third one gives 87.5% and so on. So 10.5 litres of ATF will, more or less, give you an acceptable ratio.

LOL, snap. Typed at the same time

I dont know that particular gearbox, but I'd guess you'd get a little over half out, so end with a 50:50 mix os old and new.  After a 2nd change, that'll be 75:25, and a 3rd, 87.5:12.5 and so on...

Even 50:50 is a marked improvement on 100% old oil.

You wont get it all out, so you end up mixing significant amounts of old shitty fluid with new, hence having to do a few times as each draining reduces the ratio of the old fluid.

Omega Electrical and Audio Help / Re: Sun Sensor 2

PFL and FL have different sensors. PFL/MFL is just a single sensor, FL is a dual sensor in the same dome, to tell the system if the sun is passenger or drivers side etc.

My old boss from a different life bought owned a MK2 2.8i Ghia auto.

I remember being envious, and impressed with the performance and luxury.

The MK2 is the best looking Granada.

Big bro had a 2.8i Ghia back in the day, in the obligatory gay gold. He didn't have it long, it was just too unreliable, but it was a box he needed to tick at that point in his life, having always been a Ford man up until that point.

He replaced it with a Chavalier SRi 130 when they first came out.  Faster, handled batter, less thirsty of fuel, and most importantly, bombproof from a reliability perspective.

               Handled batter? Did a fish frier own it previously then….🤣🤣

They were never the best handling car really...   ...even for the 1980s.

Yes, it is not the first time that this has happened to me after refueling, but with a slight adjustment to the calibration it was perfect. The problem is that now it does not respond and it does not matter if I add a lot or a little or even cut, the LTFT does not change. I can't find an explanation, but as soon as I put it on petrol it goes down quickly and works perfectly.
It happens in both banks equally

Both banks would therefore imply a fuelling restriction (if positive trim), so blocked LPG filter, kinked hose, tank or evap valve not fully opening etc.
