Hi Enceladus, Thanks for your reply. My circumstance is slightly unusual insofar that I am in western australia visiting grand children at this time, ( 8 hours in advance of uk time) and the omega is at an MOT garage near carlisle uk. I thought it a good idea to have the car collected by a local garage, MOT;t serviced, and returned. Garage stated car in excellent condition, and passed MOT, no problems at all. (so far so good) I was then informed when returning car EML light came on, and they returned car to garage to investigate. I'm now informed, they cannot obtain that elusive seal, and are trying to locate one. They explained it to be a rubber O ring with tabs etc down the sides. I have found this seal online, but always unavailable. If any members have one for sale, please get in touch, cash waiting. If I fail to obtain this seal, can any members advise if there is a way around this problem? As we all know, our omega's are not worth a fortune, but would be tragic to send this one down t'scrapyard :'( cheers
