My oil consumption has pretty much shot through the roof (1 quart every 400 miles) after I finished a shit ton of mods earlier this year. All these stupid threads about cylinder scoring had me thinking it was finally time for mine to go (110k). It didn't help that when I pulled my intake (for spacers), a bunch of sand fell into the combustion chamber. I was just thinking "great, I dropped a bunch of sand in there and now I have scored cylinders".
Replaced all the plugs tonight, all of bank 2 were really covered in oil but bank 1 wasn't so bad. Pulled the PCV and that thing didn't rattle at all ... which I guess means it's bad. I guess we'll see once I get a new one installed and driven for a couple weeks, but all signs point to this thing being the culprit of my oil consumption.
Since ECS is out of the generic one, guess I'm gonna suck it up and pay the dealer a left nut for this simple valve.
One of the things I read that really sealed the deal for me thinking the PCV was after I read that a bad PCV can cause the low oil level warning after driving for a while but it doesn't come back on after the car sits for a little bit. Happened to me once a few weeks ago, first time seeing that light since I bought the wagon nearly 30k miles ago.
