Hello,
I think I have sorted it. My Omega has been sat in my garage, engine supported on a trolley jack, awaiting some small Torx bolts to refit the cam sensor.
Because I have quite large hands, being 6 foot 3 or so, I found that removing the left hand engine mount afforded a huge amount of access!!. I routed the cabling the original path, as I was able to get my hand in behind the A/C / PAS mount comfortably. The sensor slipped in with relative ease and the brand new bolt (I bought five just in case!!) went in hand tight, with just a little nip up from the ratchet to secure it fully.
Everything went back together with relative ease and in 1 1/2 hours, the car was off axle stands, out of the garage, running up to operating temp. At part throttle, at 1500RPM, there's only a very slight stutter. I took the car for a fifteen minute drive down the road, through some slow moving traffic and general stop/start situation that would usually annoy it. It handled these with aplomb.
On returning home I stopped on the drive, turned the car off and opened the garage door. Usually, the rise in temperature would be enough to throw things over the edge, however, on this occasion, it started first time!! and glided effortlessly (for a 2.0) into the garage.
So, my Omega works again.
Remind me to buy a V6 again next time!!!!!!!!
The benefits of removing the mount far outweigh the fiddling around and tight space you get with the mount in place. Having the mount out also allowed me to see the sensor from underneath, it actually sits on the block, at a slight angle, which suprised me as it felt straight onto the block, if that makes sense.
It's been a long and tedious road, but we may be at the end!!
James
