Evening to one and all,
I'm kind of hi-jacking the forum as I'm not an Omega owner but have had the pleasure of getting very well aquainted with a friends Omega.
The vehicle in question is a 2003 Omega 3.2 V6 automatic, it came to me feeling a bit sorry for its self, she had mayo in the oil filler cap and dip stick and was smelling hot and of burnt oil.
I have removed both heads they have been given a very light skim and you can see staining where both heads had bled between the oil and water galleries at the rear of both heads. There was a large amount of what I describe as coolant corrosian, the white and red powdery build up from the antifreeze this seems to have caused the leak??
Anyway with the help of a Sykes Pickavant Vauxhall cambelt timing alignment kit I have rebuilt the top end replaced all the rubbers and gaskets checked and cleaned all the breathers used this site to verify and check all the vacuum pipes and breathers are in the right places BUT...
I started her up and she missed a bit, I did the pedal trick and got a list of fault codes as long as my arm, at least 10, anyway after thinking about it and reading some more posts I pulled the connection off of the MAF sensor and it ran far better. I disconnected the battery and reconnected it and then got down to four codes
P0340 Camshaft Position Sensor
P0300 Random Misfire
P0100 Air Mass Flow sensor
P0110 Air Intake something or other
So I then took the camshaft sensor out but kept it connected, I left the MAF sensor connector off and it ran a bit sweeter but idled like a pig, conducted another pedal test and I got just
P0340
P0100
Is it really going to be these two items playing up, there were no issues like this before I did the gaskets, but i didn't know about the pedal trick so didn't know if there were any codes before hand.
It seems straight forward but why would they fail just from being removed and then refitted or is it an old Vauxhall thing!!!
Anyway thanks for reading all the way down to here those that have and thanks to all those many many posts I've read whilst in the garage scratching my head with my iphone google and OOF in hand...
Any help gratefully appreciated,
on the side of this the gearbox breather pipe gave me an issue can anyone tell me where it should sit, currently I have it coming up by the 2 4 6 head at the back by the bracket attached to the rear of the head for engine/head removal and it is open to atmosphere is this correct?.....
Thanks
Dave
