Omega General Help / Re: Omega 2.2 2002 replaced head gasket now will not fire

« on: 02 October 2019, 19:09:43 »

A friend of mine had same problem. After several days of trying to find the problem he noticed he had put the wrong timing belt gear on the camshafts, the exhaust sprocket was on the inlet camshaft and vice versa.

Hi again mantamania,

Unfortunately they are in the correct place, so that cannot be the problem.

Thanks again for the input

Mike

Thanks for the input, I spoke to my mechanic this morning & he is hoping (weather permitting) to be able to look at it the car this weekend.

In the meantime I will try and see if that is the problem.

Thanks again

I am sorry that I have not reported back for a while, my mechanic has had some unrelated problems that have taken priority. Hopefully he will be able to carry on with trying to sort it out soon

How did you remove the water from the plug holes before fitting the new coil pack ?

Hi James,
I used a wet & dry vacuum with a small hose taped on the end, then soft absorbent rags to finish off.

I can't see how he could remove the head without first removing the coil pack 
have you read the codes ?

I have since spoken to my friend since seeing your response and he explained what I did not know previously..
The car was left overnight with the bonnet slightly ajar, it rained overnight and (unnoticed by him) water filled the area around the spark plugs. He replaced the coil pack without noticing the water in the plug holes.

So the head was torqued down late evening and the electrics done first thing the following morning !

Omega General Help / Omega 2.2 2002 replaced head gasket now will not fire

I bought an omega 2.2 a few months back. when starting from dead cold it usually was lumpy as if firing on 2 or 3 cylinders but would run OK after a few hundred yards and was then problem free for the rest of the day.
A few weeks back it was hard to turn over initially (one barrel was full of water), a few flicks of the key and it started with a cloud of steam....
I got a mechanic friend to do the repair (I am of the very old school and know nothing about electronic ignition or sensors).
He did the replacement without disconnecting the exhaust and a few other things by tilting the head to one side, he cleaned the block and head and replaced the head gasket.
He did not disturb the coil pack whilst doing this (assuming all was OK).
As the cams had to be removed to clean everything up I checked the valve timing with him and it looked spot on.
We turned it over a few times and it was totally dead, we checked for a spark and there was nothing.
He then removed the coil pack and it was dripping in oil and water (which must have been there from the old leaking head gasket). We cleaned it all up but there was still no spark. He thought the coil pack had been blown by being immersed in the water so i bought a new pack. there is still no spark.....
Although the air box has not been put back on (or the airflow sensor) he said all the necessary sensors are connected.
Does anyone know what else could of happened to prevent it sparking please ?
The car itself has done just over 50,000 miles being a 6 door Wilcox Limousine that had been mainly used for one purpose!
Prior to this happening most things about it looked almost like new, even under the bonnet.

If you have another Omega of similar age with identical headlights, swap the switch and see it it repeats

I had to take the switch from my 2001 2.5 Estate as the earlier 2.0 switch was too dissimilar to the problem switch.

The problem appears to have been sorted, I thank you so very much for your guidance.

I will strip down the faulty switch to see what part caused the problem and to to see if it can be repaired, I will take photographs and possibly videos of the process in case the repair is relatively simple. If I can find a simple resolution I will post the entire process somewhere on the forum to help anyone else that may come across a similar problem in the future.

Again, many many thanks

Mike

I have 2 others, one unfortunately has rotted beyond economical repair, but is being kept as a donor vehicle for the others.
It has already proved to be useful in this sense as it has a "factory fitted" LPG system from which the tank and tank electronics were removed yesterday to be fitted to the limo using brand new front end electronics and pipework, next week.

Hopefully the switches will be interchangeable, I will let you know what happens.

Again, thanks for your help

I didn't mean slap it to fix it

Does slapping it replicate the fault

Also being a six door car doesn't help with spec... It will have started out as a normal Omega in a normal trim level. The trim level may have a bearing on the fault as some of the wiring differs

I have changed my profile picture..... I feel like a dumba.. derrrr I gave it a slap and off they went another slap and back they came.
Now the fun begins, I will have to find out how to get to the switch and relevant wiring tomorrow, in daylight.

Thank you so very much for pointing me in the right direction.

Thanks again

If you slap the dash end next to the light switch, does it have any effect?

Also what spec is it?

The lights come back on too quickly to try anything like slapping,by the time I start pulling over they are back on.

It happens whilst driving in a straight line or cornering very gently on a smooth surface, so it seems unrelated to outside influences.

I guess it is a basic spec as everything is minimal including the lights, the only difference from standard is that it is stretched 6 door Limo.

Just the dash lights or headlights and ignition... ie does the car cut out?

Any recent work done?

All lights, headlights and dash, the engine is unaffected.
I have checked all the visible connections, e.g. battery and leads from it.

I have had no work done on it whatsoever, she is low mileage and looks well cared for.

I was wondering if it could be a relay.

Thanks for the rapid response

I bought a 2002 2.2 Omega 3 weeks ago and all the lights (Including dash) go off suddenly, then come back on a second or two later.
This is worrying to say the least.
Can anyone please suggest where I should start looking first as I am at a total loss ?
