Monaro advisory list
Discussion
Evening all.
Had my 2005 cv8 health checked today resulting in a number of issues, so here goes...
1.Mass airflow - range performance.
2. O2 sensor bank 1 - sensor 1, bank 2 - sensor 1 faulty.
Is it possible these 2 problems are related? I'm going to get some new sensors but what about the maf?
3. Steering rack - play and leaking.
Thinking New track rods,wishbones, top mounts. Any common areas for ps leaking?
4. Front discs.
I've got the monaro ap calipers and I can't remember what sizes the discs are 363mm x 32mm x 12mm?
5. Transmission noise and vibration that needs further investigation.
I can get all gears apart from reverse which needs a gentle knock to get it in otherwise it'll pop out. There is some noise at slow speeds say 20mph coming from the rear somewhere. Doing a bit of reading it seems the monaro is a bit noisey but being my 1st I've nothing to compare against.
Tia for any advice,
Ste

the 02 sensors are not too difficult to change, as long as thread does not strip a bit of wd40 a few days before , i ordered mine from australia you just need to know which ones they were about 40£ or so for a pair of them , the plug is either flat or square so easy to id , i would do them and see if the maf resolves itself , if it does not try some maf cleaner first as you have nothing to loose by trying that , but only clean if it is showing an issue as normally not advised to clean it , you need to track down the ps leak , there is a ps cooler in front of the rad and are common to fail not that difficult to do , contact mokfish for the discs and any other parts , they keep a few options parts wise but brakes are not cheap , a clunk in drive train is normal but worth changing rear diff oil , some one posted recently which oil to use as no modifier is needed , the modifier is a friction additive , gearbox wise noisy is fairly normal , some times spigot bearing is an issue that is box off to change but some times noise is fine , mine has always been noisy and has been fine for last 5 years but how noisy is yours ? some times a bit of drive shaft play or a bit of a worn propshaft doughnut , struggling to get gears is normal spigot related but reverse is not unusual to be a bit of a fiddle so it may be fine , steering play probably the track rod ends , a quick rack works well and not too expensive , any thing else i think i covered your questions
02 sensors are often lazy and maybe better than what you think they are but you need a laptop program to read it if they are sitting at 500 ? i believe it's 500 and not moving around they are knackered , 02 sensors faults some times come up on the dash for no reason , i wound not be lead by a garage who don't know the car as they are quirky and quirky can be totally normal so get things checked out but some things will be fine , if discs worn then yes need doing and ps leak , and play may need doing how much play as there play and plaaay if you know what i mean , any local members to you who maybe able to advise ?

Thanks for the info, much appreciated. I'll check the sensors tomorrow then and get them ordered. The car is running without any cats so throws up the check engine sometimes, mostly in 6th but also 5th. He cleared the o2 sensor fault, the car felt a bit better on the way home but the check engine error was on again 3 or 4 times and by the time I got home the car felt like before although that could be all in my head lol.
I'll change the diff oil, it has been done recently according to the history but I'll do it to rule it out.
The gearbox is not really that noisy in my opinion, there's a little speed related hum which could be the diff, I don't know. I don't hear any nasty knocks, can get all the gears other than reverse. Maybe he's seen something from underneath.

When parking the wheels / steering is making clunking noises so I think I'll probably refresh the front end and get the pas sorted at same time. I'm going to break it all down into manageable chunks lol.
Yeah probably a good idea to meet up with someone local so I can compare noises.
Cheers

a bit of clunk maybe normal depending what the issue is it's difficult to diagnose , it sounds like some issues are not issues but picked up by persons who don't know the car and it's quirks
Yes this could be very much the case lol. It's not like I drive the car and think the gearbox /diff are about to fall off. An '05 CV8 has 1 pair of lambda sensors if I remember correctly, so if you're running no cats that won't effect it as they're before the cats just after the 4 into 1 collector of the headers, as already said they do throw up faults quite regularly but are nothing to worry about. When you look at the PAS cooler infront of the rad be careful as the pipes rot quite badly and they can snap. Gearbox problem/noise as also already said are normal, they are clunky and noisy but if it is the spigot bearing get it done, it costs a few quid and it will take out the gearbox if it goes and they're like rocking horse sh
t. I also agree with last poster, get it to someone who knows these cars as they're quirky and different. Normally any clunking coming from the rear/underneath is the prop shaft donut, there's plenty of play in the driveshafts at the diff but the diff is solidly mounted to the rear subframe so if the bushes are on the way out then it moves and transfers the noise into the car when taking up the slack on pulling away. Hope this helps

the 02 sensors maybe fine , there are extension bungs for the 02 sensors that if there stop it throwing up cels , some one will be along to clarify this i'm sure , no cats will be an mot failure what about getting some sports cats welded in
Yep was already on the "to do" list fitting some cats. Just adding some o2 sensors to it.

Ok I'll check the sensors out, I thought there was 4 in total, probably me lol. t. I also agree with last poster, get it to someone who knows these cars as they're quirky and different.

Hope this helpsYes definitely helps, thanks for the heads up with the spigot bearing, I'll get it looked at as I don't fancy a new box lol
Ok so I've just had a drive out, it's all pretty quiet round the back end. The only noise is happening between 0 -25 mph occasionally, sounds like it's coming low down wheel height. It's not a squeak or clonk more a groan lol.
Gearbox feels good, all gears present and happy other than reverse. Got a ripshifter fitted, might give it a clean up.
I know it's hard diagnosing things on the Web so thanks fellas, appreciated.

monaro only 2 02 sensors , spigot not easy to diagnose you tend to struggle to get forward gears , i'm running mine till it may or may not break , i've never had a spigot issue gearbox slave leak and changed the spigot but never purly a spigot issue , and on both cars spigot was still intact
Could the noise be a wheel bearings at the rear ?
Last month I changed my o2 sensors ordered mine from Australia from what I researched there are only two on my car 04 cv8 and my sensors had the wiring connector block in a strip, the later cars had the 4 wires in a square pattern just check which you have before ordering. Mine were 4 wires in a line I replaced both and paid about £80 delivered.
My engine check message had started to come on after a minute or two of driving but only the message on the digital display. No lights on changed the sensors ASAP and message never came back, call ran fine for the week or two the message popped up every now and then but mpg may have been down a few I assume because of over fuelling.
Also a few years back my pass cooler started to leak, monkfish didn't have any in stock so ordered new hoses and a universal pas cooler from driftworks.

There shouldn't be 2 pairs of lambda sensors on an '05 as only the later ones had 2 sets, is it a facelift on a '55? Whatever the reason you've got 2 pairs is irrelevant, if you've got a pair pre & post the cats then you will get lights up and messages as the readings will be miles out due to no cats
