hi grumpy

it's just a case of thev'e modded sensor again. you know like the bas****s have a habit of doing!!!!!
but as TB says if it fits . . . . . . . .

[Grumpy]

Thanks for the replies, guys.

Just examined the old sensor more carefully. The sensor head is cracked
near where the cables enter it. At the very least this will be letting in
moisture, so it deffo needed replacing.

Tried pulling the old sensor cable through between the power steering
pump and the back casing of the cambelt cover, (where it's routed),
but no chance. This item must be fitted during engine manufacture
prior to fitting the cambelt cover and or power steering pump.

So I've cut off the plug and will re-route the new one. I think folk do
this on the V6's as well?

Anyway, at least I've proved that it's possible to do the job from the top
after removing the exhaust manifold heatshield, than jacking it up, removing
the engine mount, and scrabbling around on your back.

You have to work blind, feeling at full stretch with your fingertips, but from what
I can gather, reading these threads, that's no different to what you have to do
when replacing the Dis pack on the V6's.

There is a guide in Maintence Guides section for cable routing...

Crank sensor replaced. The new one did fit ok, even though the
shape was different.
All seems to be behaving itself.

Starts fine, no rev limiting.
Idle speed steady at 750.
Engine temp steady around 93 to 96.

Took it for a good run. No stalling or cutting out, so far.
Time will tell.

No point in doing paper clip test yet, as no EML and I believe
you need a certain number of clean starts to purge the fault
codes from memory.

Job is very awkward to do, due to access. If you have dinner plate
hands, or don't have a 1/4" inch universal drive socket adaptor, or
mechanical fingers to refit the bolt, I doubt you'll manage it by my
method of removing the exhaust manifold heatshield and working
blind from above.

If you follow the oil dipstick tube down to the crankcase, the crank
sensor is mounted about 2" forward of that behind the power steering
pump. You can't actually see it.

Haynes suggests jacking and removing the engine mount. This may just let
you see it, but I doubt it will improve access. The oil dipstick tube restricts
access something terrible.

If you can't access it from the top, I suggest an easier method would be to
remove the power steering pump, not the engine mount.

This job would be made easier from the top if the oil dipstick tube was removed.
But I have no idea how it's fixed in position.
Has anyone ever removed one?
Is it screwed in?
A push fit?
Secured inside the crankcase?

Shout up if you've actually removed one.
No guessing or anecdotal evidence please, if you give duff gen
someone may snap it off. You need to have 'walked the walk' here.

Right, ready for the next job, whatever that may be.
Never a dull moment in Omega ownership, is there.

i'm just waiting for the next thing on mine!!!!

So's SWAMBO ! She's got a deep, pathological, mistrust of this car now.  

She's learned a few new curses and swearwords off me the last few days,
and is none too impressed.

Reckons I've become very coarse since buying our first Vauxhall.  

[TheBoy]

Think how much you've saved

[Grumpy]

A quick update, as I think it's useful if folk give some feedback
as to what actually fixed a certain set of symptoms.

Just got back from 4 day mini-break. The car did approx 600 miles
under all sorts of conditions. Motorway, stop/start urban, up and down
Cumbrian mountain passes.

Ran like a Swiss watch. Not a cut-out or hiccup in sight.

Moral of the story, at the first sign of a Crank Sensor fault code , get
it changed before it bites you on the bum.
