Omega General Help / Re: Polybushing

Red Strongflex and purple Powerflex have same hardness 80 ShA. From first above links it says that it is a similar hardness as rubber bush would have.

For the price of one purple Powerflex you can buy one red and one yellow Strongflex to compare

What grease did you use?

Did you find any difference after changing the front bush from Powerflex to Strongflex?

What improvement did it have on steering and handling with just the front poly bushed changed and rear left standard?

What improvement did it have on steering and handling with both the front and rear poly bushed poly bushed?

Thanks

I used the grease that came with Strongflex bushes. I used it plenty to all surfaces where metal to bush contacted.

I found some improvement how steering and handling felt when replaced front bush from Powerflex to Strongflex because different in stiffness. It felt a bit more steady to drive overall.
But I must say that Strongflex was better design. There was grid groove where centre metal tube is inserted. This helps greasing it better. At Powerflex there was nothing, only flat surface that wont hold any grease on it when you push that centre tube in place.

I had pretty new rubber bushings before I fitted polys, so I think there was not so much noticeable difference that I wished for. Maybe when cornering difference between rubber and polys could be noticed most. And of course in time, when rubber loosen up polys show why they are better.

Same thing with rear bushing. I did not even wanted any improvement for steering and handling when I changed rear bushing, all I wanted was not to worry about rubber bushes to wear out.

It looks rusty/dirty inside that bushing.

What I've read, poly bushing binding can cause problems like that when there is no grease or not suitable grease used (some may consider it as installation fault).

I could easily move my wishbones up and down with very little friction and no noise coming from bushings when I removed struts out of the way. I bet there is much more resistance with regular rubber bushings when comparing movement against (properly installed) poly bushings.

So far I can say that these bushes are not moving the flex from the part that is designed to accommodate it, but are even making it easier to flex.

Last week replaced strut mounts + bearings and ball joints so was able to check wishbones. No cracks or other faults found, all good with both front and rear polybushings fitted.

Good to here that all is still good.  How long have you had them fitted?

Is this still correct, you have Powerflex in the front and Strongflex yellow for the back bush of the wishbone?

What make of wishbone did you use?

Thanks

I fitted first Powerflex to front bush (if I remember correclty, over 2 years ago).
Then fitted Strongflex to rear bush over 1.5 years ago and (again if I remember correctly) near that time replaced front polys to Strongflex yellow ones that are a bit stiffer than Powerflex purples (90 ShA vs 80 ShA).

So now I have both front and rear bushes Strongflex yellows fitted.

My wishbones were replaced about 5 years ago when I purchased my car, job was done by local garage and I dont know what brand they used.
About 50 euros each.

Does it make same noise when you jack front up and turn wheels?
I had same kind of noise coming and I was sure it is top mount, but it was ball joint with puncture on its rubber sleeve that was probably full of dirt and making all the noise.

Worth to check if you cant find solution from strut end.

I've read that some have successfully welded those manifolds in-place.

Before welding drive/rev engine hot as possible so exhaust manifold is very hot, disconnect battery and then quickly weld with applicable welding method and then wrap the whole manifold with rock wool and let cool over night. This should prevent repaired manifold to crack/bend.

Got Poly bush idler arm on mine all good atm

Are these available somewhere?

I have brand new idler arm installed, and when I jack wheel up and push/pull it from 3 and 9 o'clock I can see idler arm head (point where it attaches to centre tie rod) move up/down about 0,5 cm.
Or should I just modify better bushings from some general PU bushing and fit them to idler arm

Or still that exhaust manifold crack messing up idle and low revs?

In light of the manifold crack... Best add it to the list

Cheap and cheerful...

Hopefully someone can confirm that it will fit

2.2 does not have secondary air injection as far as I know. I have found in the past that the exhaust gasket studs in the head are inclined to breaking off. On Ben's 2.2 the 2 front studs are missing - amazingly the gasket is not blowing at that point.

Here's what I got few years ago: https://www.vauxhall-car-parts.co.uk/acatalog/VAUXHALL_EXHAUST_MANIFOLD_-_24420438.html

Back on topic Not much other traffic about on the clip helps. Not meeting the idiots.

Spotted one idiot crushed under light pole (driver and passenger OK) and other three crashed together (no damages there either) on the way home that night.

But yea, even in Finland there are drivers who stay at home when shit hits the fan

There was small snow storm yesterday. Omega went like a train through it

How do you manage not to laugh at all the idiots here in the UK who can’t get about in a couple of CMS of snow?

I imagine he does laugh.. and wonders why we don't fit winter tyres like the rest of northern Europe

Only the highlighted part 

And I understand that if there is only couple of days or weeks winter conditions per year, it might be too expensive to buy proper winter tyres for that time period.
But at the same time I need to say that Omegas (and any other car) snow performance, as the topic says, is all about your tyres and driving skills/experience in the end.

EPC lists p/n VX-24406212 as being 0.5mm oversized, but also says NLS and a quick Google doesn't look promising.

https://opel.7zap.com/en/car/v94/e/5/17-1/

How much oversize are you looking for? There are several 'standard' sizes which give you up to 0.05mm of wiggle room :

VX-24405799 PISTON,PIN AND RINGS,ASSY.,STD.,CYLINDER BORE 87.475-87.484 MM (IDENT 08) (NLS.- NO REPLACEMENT PART)
VX-24405804 PISTON,PIN AND RINGS,ASSY.,STD.,CYLINDER BORE 87.485-87.494 MM (IDENT 99)
