I have just purchased my first Omega

, It has its probs but I was so taken with its styling

and the bodywork was mint too, which is a bonus.
Downfall is I might have head gasket trouble.
The emissions light is on.
The running is missing a little, its enough to pass though to your seat when idling.
Im loosing water from the system and slight vapours from the exhaust. I cant see any signs of oil in the header tank and there is only a very slight milking inside the oil filler.
I have taken the car for dianostics, which was a keyfob tester and came up with various unidentified codes, and one that said there is trouble with number 4 cylinder.
I am still doing more investigation and I have it booked in again next week, I'll push them in the direction of pressure testing.
Are omega's prone to gasket trouble and if so is there a hot spot were they usally go.
Hope to get this sorted as soon as possible so I can go for a real cruise.
Thanks Russ
