The V8 Adventra is a bit of a beast if you can find one for sensible money 8)
Interesting..........

Well, it seemed adequate to me. :y
When did you last drive it? The Monaro front end was fitted after that Brackley meet ;)

Much improved over the Omega subframe  :y
I keep finding myself browsing the sales sites looking at Holden V8s. Generally the V8s are top money or  slammed or sheds (or all 3 in some cases)

This one looks unmolested https://www.trademe.co.nz/a/motors/cars/holden/commodore/listing/3121880971 for about £6,000

Omega Electrical and Audio Help / Re: Crank Sensor Failure
« on: 26 June 2021, 23:08:47 »
Lizzie,


if the Bosch sensor you've sourced is NEW, fit it and see what happens. OOF dogma is that only Vx sensors are dependable, but that's from a fairly small sample size compared to the total number of cars. If yours works, and continues to do so, then you're done. If it doesn't work, then you can use the one you removed(assuming that it is genuine ::) ) to acquire a replacement.


There are very few parts that have to be genuine if alternatives exist. And as I stated in my previous post, I would be very wary of certain parts that are best considered NOS. I've bought NOS Girling hydraulic cylinders from one of the classic specialists, and they supplied them with the recommendation to replace the seals with the new ones supplied.
The genuine sensor IS a Bosch sensor. Bosch make it then GM stick it in a GM box and add their mark up.

Knock off copies probably copy the Bosch logo on the plastic moulding.

The crank sensor is a very simple device - a coil of wire wrapped around a magnet. What is difficult is making something dimensionally accurate (the tip of the sensor needs to be close, but not too close, to the teeth on the ring on the back of the crankshaft) and making something that can cope with the heat (magnets become non magnetic when they are hot and the insulation becomes brittle - especially where GM ran the cable too close to the exhaust manifold).


I know, and agree with all that. Hence my suggestion that she try the one she has coming, rather than worry about buying another one that's going to be better because it's genuine.
:y

15 years ago I bought a Bosch coil pack for my Omega from a Bosch service agent. Struck me that I had a pretty good chance getting a genuine part  :)

IIRC it was about half the price of buying from a VX dealer and they had the part in stock.

The place I went to was in Luton & only sold parts, don't know how I found it now :-\

All the searches I have tried come up with indi workshops.

Extracted (with some difficulty) the bush from an old steering idler. Then cooked the idler casting in an oven for a couple of hours, while a brand new GM bush, previously extracted from a new Senator idler sat in a freezer.
Then pressed the new bush into the old idler. So I now have, to all intents and purposes a new GM steering idler.
Will fit it to the car at some point when Im in the mood. The one on there currently isnt in too bad shape.
Air in the ABS module?

I think Tech2 can trigger the ABS to pump the bubbles out (may be wrong there  :-\)

Have you tried 'back flushing' - (pump brake fluid into the bleed nipple to force the bubbles back to the reservoir)

The only time I have had to resort to back flushing is for clutch cylinders (on old Range Rovers) , everything else has flushed through easily using an Easy Bleed.

Stealth mode on?

Given the eyesite of an ageing population I wager a lot of these cars won't be noticed  ::)

Sadly, this really is part of the day job, as there are fewer environments which present such extremes of temperature as automotive (-40degC up to 95+degC ambient is not unusual)

One of them is aerospace, where stuff has to work in ambients between -40C  (Parked in the open in Norway in Winter) and +125C (parked in the open in Saudi Arabia in summer). Initial internal temperatures can exceed 200C before the Air Conditioning in the avionics bays gets the temperatures down to 125C. Then they take off, up to 40000 ft where the outside air temp is -40DegC.

You wish.
I couldn't resist a 'quick' internet search which turned into a longer one which reminded me of a rule of thumb of 3C/1000ft for the drop in temperature as you climb (lapse rate). We were taught this as Scouts before tramping up Snowdon (3000ft) and Ben Nevis (4000ft).
In theory you take the temperature at ground level (say 20C) and subtract the height in 1000's x3 to get the ambient (so 20- 40x3 = -100C)

3C/1000ft is a rough approximation used to encourage spotty Scouts to carry some warm clothing. Shackeng can probably give us a better approximation  :)

How did you manage to crack it down under the bumper??
A 'little tap on the nose' would do that.
The big plastic panels then spring back into place leaving the internal organs battered and bruised.

I would roll the engine and gearbox over far enough to get to the TC bolts from underneath. The dipstick has o-rings to stop it leaking so roll it that way (passenger side) not the other way else you will have sump oil pouring out of the breather box.

Omega General Help / Re: A question on radiator numbers 2.6
« on: 06 June 2021, 23:12:49 »
Don't worry about the transmission oil cooler built into the drivers side of the rad.
The 2.6 doesn't need it but it doesn't do any harm either.

Mine's has the seperate trans oil cooler in between rad and condensor. I take it then there is a version with the built in cooler and one without, but either will fit?
Yes
Broadly speaking the pre-facelift / 2.5 & 3.0 V6 had the oil to water trans cooler in the main engine radiator and the facelift 2.6 & 3.2 V6 had the separate oil to air cooler. The only outward difference is a couple of screwed connections for the oil cooler pipes.

Would a Carlton wheel fit? Potentially a cheaper cock sprong without the airbag or steering wheel controls...

 ??? :-\ ;D ;D
Oops :-[

Was that what they call 'mansplaining'?

There was an amusing story with this operation. On checking in to the hospital I was required by a doctor to sign a disclaimer, which, in the small print, allowed anyone other than the consultant to carry out the op. Not happy with this, I crossed that section out before signing, and said doctor was somewhat discombobulated.
Arriving at theatre the following morning, feeling quite mellow after the pre-med, the consultant pulled his mask down to identify himself as he leant over, saying with a smile,  “Satisfied?” ;D
;D
I pondered the same small print before my eye op. Came to the conclusion that if the choice was between the named surgeon or being sent home I would rather have the op.

Fitted new front anti roll bar bushes to the Mazda. Bushes are cheap as chips but a bugger to fit as you have to drop the front subframe to get a spanner anywhere near the mounting bolts.

Such a relief to finally get rid of the low level knocking noises (at 4th attempt)
1st - replaced leaking fluid filled engine mount - cured engine vibration but knocking continued
2nd - replaced drop links. Nothing wrong with the old ones :-(
3rd - paid to have new strut mounts fitted. Mechanic showed me the remains of the old ones but the knocking continued  >:(

Just need to fix the clip on the sunvisor now because the rattle is getting REALLY IRRITATING  :o
