So my 2007 has 235k. Second owner 3 years about. Put 35k on it, including to Panama and back to SF Bay Area, solo. Well with dog.
So i decided to look at and OEM replace PCV related stuff. Guess what? That was original, tough as nails to unscrew valve, parts were oily. Hoses cracked and broke. Dealer did two major services and did not mess with it. These are to be replaced considerably earlier too. I did it. Only pain was unscrewing old valve. Replaced all rubber hoses and fittings. All bueno now.
