Z1 FRSL losing air in cold weather

Does anyone have a solution to a Z1 FRSL losing air in cold weather. It holds for about a half hour then loses all air. Air leaks from the seals not valve. Thanx.

I've had the same problems except it seemed like more of a sudden loss. How do you know it was coming from the seals, not the valve?
I could hear air escape and see tiny bubbles from the seals when trying to pump it up.. It is also a sudden loss of air. I put air in the fork the next day (bike in basement overnight), and I can hear air leaking when compressing fork. So this is not just a cold weather issue. The stanchions felt oily also. I bought the fork nov.04, so out of warrenty . Unfortunatly this happened last winter only twice so I didn't do anythig about it. I never worked on a fork before. Thinking of replacing the seals myself.

Check Enduro Fork Seals

Enduro has not only seals but has nice pictorial instructions on how to swap them.

It could be your stanchions reducing in diameter for the cold. Rubber it's not so affected, so that could be. The problem you didn't see it much last year as your seals were still tight and with some wear this year it could be worst.

Well, it is normal for the rubber seals to get stiff in cold temp. Thus they don't fit perfectly to stanchions. Now, if they are worn out that means you'll have no choice but to junk them and put a new set on. But before you doo that, you should check your oil level, coz it can happen that the oil is too low and doesn't cover the seals all together causing the air to hiss out more easily...
thanks all for your helpful info. I spoke with a Marzocci tech, he informed me I have a 2 year warranty so I might be in luck. The tech was very accommodating which is nice in these days of indiffrent service.
