I am newe to this forum, I recently purchased a 2002 Jetta TDI. Have a 2002 Ford SuperDuty with the Powerstroke, thats a major reason I invested in a TDI..Diesels ya gotta luv em !! Anyway have read numereous posts about intake build up, my Jetta has 7800 miles on it, I use Rottela synthetic. Has anyone had any experience with the Racor crankase ventilation filters ?
