Just check as some tyres are directional
Possible there is an arrow telling you which direction they go. Maybe they should only be fitted with white ring on outside

It doesn't matter that they're directional if you re-fit the (current) right on the left and the (current) left on the right. As long as the sipes point the right way and they have a symmetrical tread pattern, you're good to go - they'll be facing in the right direction. You just can't reverse the tires by flipping them 180º. So you can't swap the wheels over with directional tired, the tyres have to be removed and refitted onto the opposite rim.

(As a general rule of thumb, tyres that are, for any number of reasons sided as well as directional generally don't have graphics on the inside wall)

You'll just have to put 'white-bands' on the back to even things up, Tim - I like them & think that your car would look fantastic with 4 on.... :w

No, absolutely definitely not doing that. :D

No, Tim, I agree.
IMO you ought not to paint white rings on the rear tyres; your plan to reverse the tyres on the rims makes sense to me, and if they have directional arrows on them, switching them across will put everything right, although I expect you already knew that.
Best wishes for the season,
Philip

I don't know who suggested painting white rings on the rear tires but it sure wasn't me... It's a horrible idea anyway, but it also overlooks the fact that I like the rear tyres, its the white rings on the front that I don't like. But you are absolutely right about directional tires, It doesn't matter that they're directional if you re-fit the (current) right on the left and the (current) left on the right. As long as the sipes point the right way and they have a symmetrical tread pattern, you're good to go - they'll be facing in the right direction.

Black tyre wall paint just to temporarily numb the pain?

Haha, yeah, it's an option. I already used a grey Posca pen to temporarily tone them down from *Donny Osmond's Teeth* to *Dear old Granny's ashes*, but it's actually the entire aesthetic that's wrong, so blacking them until I can flip them is not a bad shout at all.

The rear tires are meant to be a quietly menacing declaration of understated, alpha-male, automotive aggression. A low, whispering growl of "don't mess with me"... but they are completely upstaged and drowned out by the front tires waving excitedly and shouting "HELLO EVERYONE, I'M ELTON JOHN!"

Hello, It's AnotherTim here.

I haven't been here for a very long time. I debated whether to drop in now as I decided a while back that my time here was over and I was better suited to other online environments.

However, I've decided to drop back in quickly just to make Essex users aware of a thing I found this weekend. It might be something, it might be nothing... might just be a one off. I do feel it might be worth checking yours however if you have also fitted the item I've come back to mention.

It concerns the Webcon W atomiser plate for the Essex. I purchased mine through BurtonPower last July. Before I even fitted it, I made a comment somewhere in this forum to the effect that I had some misgivings about the material these new replacement W-plate pieces are made of. The old pieces as you may know are a very dense, very smooth and very precise material. The Webcon items are a white material, and they have a texture and a lightness that to me felt a little crude, unfinished and insubstantial.

But I fitted my new piece at the end of July last year and it seemed fine.

It did however, begin to discolour on the visible edges. I assumed it was reacting to heat and also just attracting natural dirt to its outer surface in an old engine bay.

For various reasons I decided to remove my carb this weekend, so I had the W plate item off to have a look at how it's doing.

It's a very odd material. It appears to be compressed fibres not a solid block. In some places it looks and feels like a nylon weave and has a waxy nylon feel to it. In other places it even appears to be fibreglass or carbon fibre weave (it isn't carbon fibre it just looks like that). A friend online has just suggested "looks to be made from GRP fibre board not the best of applications for that material even in fire retardant resin".

Having removed mine it became apparent it wasn't merely the exposed edge that was dirty. The entire material has soaked up fuel and the discolouration runs through the material. It also appears to be delaminating. Most telling of all though, one of the internal lugs has disappeared completely. It has fallen off so smoothly there's no evidence it was ever there. Another lug rocks back and forth like a child's milk tooth the day before it falls out.

So I just wanted to pop back and say that if anyone else has ever fitted one of these white Webcon W spacer plates it may be a good idea to have a quick health-check at some point in case your engine has been chewing lost bits of it. I would remove it very carefully and keep your eye on the lugs that form the internal apertures in the barrel walls as you remove it. My missing lig may have already made it's way through the engine, or it may have toppled in as I removed the piece yesterday. It's tough enough stuff in a lump that it could cause valve damage if it passed through as a lump rather than flaking into strands.

As an optional anecdote I had a short series of bad coughing spluttering and loud misfires from the NS bank/exhaust a while back, and there was no rational explanation for it that I could find. After a while it cleared never to return (touch wood), but my working theory is that was y car coughing out the missing lug. It may well have caused valve damage to some degree so now I'm looking into that.

Now I need to remember how to upload photos here, but hopefully this will work...

Here's a picture of a remaining lug. It wobbles back and forth with the merest of effort and is like a stack of papers waiting to fall over...

Here's a picture of how the strata are delaminating. The picture doesn't show it quite as well as running a finger tip gently up the hole where you feel and hear how this upper layer has parted...

This is not a 'slagging a supplier off' post, this is merely a head's up for anyone else who fitted one of these and has not checked it since - it could be of potential benefit to individuals, it is not a public condemnation of a company. I just thought I ought to share what I found in case it makes a positive difference to somebody else.

That's all. I wont be back to discuss, I just wanted to let you know. Happy Scimitaring everyone.

I believe the material may be tufnol, in which case it is an insulator made of compressed resin and fibres, and once damp with oil or fuel, will remain waxey to the touch

Thanks for posting Tim - quite surprising that.

I've wondered whether it would be possible to 3D print them - I know very little about the process though, and whether the material is suitable.

Cheers,

Mike.
