BACKGROUND. As some of you know My wife drive an 09 WRX. She loves it, me not so much. It has over the last 4 years run low a few times on oil within one week it can drink 3 quarts of oil. Normally the only sign has been a P0011 passenger side variable cam timing. I try to keep a close eye on it as possible. Last month the P0011 came back oil was clean and level was fine but did a change with my normal K&N filter and Castrol Edge (seems to drink less then other oils). The dam light would come up offten enough that the I/M readyness was keeping us from inspection that was due today.
CURRENT ISSUES
Last week I pulled the drain plug, let it drip while I pulled the filter and then moved top side pull the air box to TB rubber tube to gain access to the VVT solenoid. It looked clean but i made sure to clean it anyway while cycling power to it. Due to a bracket blocking my path i could not pul the oil line to the turbo off the VVT near the top mount, nor off the bottom of the turbo that banjo is stuck. I used compressed air and a rubber stopper on the blow gun to push air into the VVT solenoid hole hoping to push any oil gunk out of the cam works, then replaced the solenoid, replaced the intake hose. Then moved under the car and pushed air in to the oil filter mount untill the oil stopped flowing out the pan I'd guess i got close to another quart out. This time i used Mobil 1 oil 0w-20 as it was cheap and thinking was thiner might clean the VVT works better plan to run it only a week or two.
Well light has stayed off! I got the inspection done!
Now at long idles i can see smoke out the exhaust and just as i think it builds boost (no gauge err.) We hear a howel out the exhaust but might be turbo? could be a hose i bumped?
Any ideas on WTF it is? It's not drank any oil yet... Wheres the PCV on this system could that be messed up.
Sorry for the whole page post..
