Thanks Roy the bus is in constant use, so will be trying the drip tray whilst trying to get a replacement gland. Not sure that company yet makes Llewellyn gland seals, they supply accumulator seals, but Imperial are trying to get the seals made as that it the part that causes all the problems. Will know more on Monday.

My bus number (if any): RTL 960, RM 1585 and several RTs

Imperial listed Llewellyn glands on their website recently. I may have decent 2nd hand one if that's any help.

My bus number (if any): RML2532

Thanks Roy, only just seen this, It became urgent and Imperial are sorting out a refurbed one for us and I understand are getting the seals made for refurbishing others.
