Hi, just starting getting the z ready for the new engine and noticed one of the tyres was flat. Turns out the leak is coming from the valve...

 

Looked everywhere but can't seem to find any the same. Wheels are Advan Siena 2, the valves are a long bolt in valve which are bent at 45 degree.

Did you check ebay out,

You will need to check fitment.

Cheers buddy, yeah they all either seem to be 45 degree angle and short like those, or 90 degree angle and long.

 

From the end of the valve to where it comes through on the inside of the rim is 5cm, so i need them to be 45 degree and long!!

 

The only info I've found is someone on a Supra forum getting some centre caps. He went through Volk who are (were?) the Advan distributer in the States who sourced them from Japan.

 

If all else fails I may just get a standard valve fitted for now inside the rim, and get all 4 valves replaced when I eventually have the wheels refurbished.

Where's it leaking from on the valve? Any chance you could remove it and have it repaired?

Just guessing here but from the pic there seems to be a rubber gromit, it could be that and that would on the face of it seen easier to replace. Have you pinpointed the exact leak? Get some soapy water and regularly the tyre with air, see where it's coming from.

Yeah its coming from the rubber grommit.

 

Should have mentioned I had the same issue when I had the tyres fitted two years ago. I believe there is no rubber o-ring there as standard but the tyre place said they can try fitting one but said it might not last that long.

 

Back then I was also unable to find a replacement valve but we were looking more at local options. From what I've seen all the screw together type of valves have some kind of rubber o-ring though?

 

I would like to try and find new valves if possible as got a feeling another o-ring won't last long (the one fitted ended up just sitting between the normal edge on the valve and the wheel, rather than having a groove cut for an o-ring, if that makes any sense)
