I am having an oil leak issue with my 2001 X5 4.4i - Dealer in Winnipeg says that the engine vents are frozen and needs the retrofit kit. He quoted me $4800 for three days of work! This seems extraordinarily high...

Am I correct in stating that the oil separator is similar to the crankcase vent valve - or are they two different systems? Talking with a mechanic buddy of mine online - he says that a PCV switch shouldn't be that big of a job.

How feasible is this job for me or for a local mechanic to take on? I don't really want to have to get the X5 flat-bedded to Winnipeg for some work if any shop can do it.

Thanks for any and all advice.
