Harmed? Nah. If the one you're talking about is the one right on top of the cylinder head there, it IS part of the PCV system, so you were correct in that. Change your oil...like, tomorrow or this weekend...if you haven't and everything'll be good.

As has been described, The 850's don't have a PCV Valve, they have a PCV "System" that is about as complicated as the space shuttle. Search through the repair database under PCV for more details. It really isn't that bad of a job except for one nut on the intake manifold that hides behind the alternator.

I like how you say it's as complicated as a space shuttle, and then say it's one nut on the intake manifold. Ha! Oh wait, I see, except for that one nut!

Well I did the warm motor/dipstick check yesterday, looks like I have some work to do, but at 186K, I cant complain. I left the dipstick a teeny weeny bit loose, I'd rather not have to do the rear crank seal or whatever blows out.

Is this ok to do, and will it blow oil out of the dipstick hole while driving? I'm considering doing this, frankly because I don't want to do all the PCV work since my car is old with high-mileage as well. I seem to have lost a considerable amount of oil since my last oil change (a quart or so in 600mi.).

I tried that for about a 40 mile drive when my PCV system was clogged, and it blew a bit of oil all over my engine, and I definitely smelled fumes from it while stopped. Then again, I did floor it to pass a truck climbing up a mountain at 15 mph. If you don't do that, I suspect you'll be ok :wink:
