Hi
Valve seals have been a success. After 500 miles I cannot detect any chance in engine oil level. Smoke is gone as well. I do not run 20W50 though. After wading through some oil threads I decided to use 5W40 from Mobil1 instead of 20W50 which is too thick for a New England winter (although it has been very mild so far).
As usual though, the little diva needs attention again: the rear wheel bearing is about to fail.
Thank you for your comments, Bruno
