Hi there,
I tried searching the archives for "PCV" and "Flame Trap," for the 1993-1997 850s, but did not see a definitive answer for servicing the PCV/flame trap.
Aside form the mileage (two 850s; one at 85,000, the other at 76,000) and use (no hard use), if we want the 850s to go another 20 years should the PCV/flame trap be serviced no matter what?
I understand it's a fairly expensive, time-consuming procedure, and not always necessary, but the key is that there's no definite way to tell if it's necessary.
What I don't want is a blown seal anywhere. We have done the glove-over-the-filler cap test (no pressure one way or the other), and there's no smoke from the dipstick.
Do you think it makes sense to just do the service?
Thanks!
