I've decided to take the plunge and replace the PCV. The car is running very well at 135K but has the tell-tale sign of a smoking dipstick. I also use synthetic oil and change it every 5 - 6K. I thought it might just have been cold weather and short trips causing a smoking dipstick to be a sign of condensation burning off, but the warmer weather and a long trip still showed signs of a smoking dipstick. So how to proceed?

I read where some have used Seafoam to clean out the oil separator. They pour it in the oil separator via a vacuum hose and let it sit overnight and then go for a drive. Any comments on that? Others have been able to salvage some parts from their old system and just replace those parts. For example, eeuroparts doesn't have the full kit replacement like fcp does. Eeuroparts sells the pcv system part by part. Still others replace the whole thing. What are the best options? What has been your experiences with any one of these approaches?

Thanks, George
