New to this site and only posting my 2nd thread, can I ask what was it that drove you to changing your CCV valves? I cannot find in this thread why yours needed replacing.

I have a 645 that blows blue smoke after standing idle for any length of time and have read it could be CCV Valves. I'm praying this is the solution as the alternative fault (valve stem oil seals) is highly expensive.

Kind regards
