Hi all, I get a puff of smoke on start-up now and again, especially when the car has been standing. I believe it is the oil seals on the end of the valve stems, which harden with age. Anyone know if this is likely and how difficult it is to replace them? I guess it's a job for a dealer/specialist? Regards, Peter
