So on my way to work this morning... I was thinking to myself "wow, the RX sure is running great this morning. Hope it acts this way all weekend so I can drive to Reno tomorrow".

 

And sure enough, as soon as I said that the car started to sputter. I was cruising in 5th gear, so it wasnt really that noticable, so to verify I floored it. I have no boost gauge, so I dont know how much boost my turbo was making, but everytime the boost light was on my car would sputter and in the rear view all i could see was a plume of blue smoke.

 

About a block from work it quit doing it.

 

WTF!?!?

 

Most likely a leak in your hose routing for the IC, When you aren't boosting the cars running a bit lean from air coming in that's not being measured by the maf. When you are boosting air is escaping that's being measured by the maf so the engine runs rich cause that air it supplied fuel for is not in the cylinder it's under the bonnet somewhere :/

No more intercooler. Everything is bone stock. Stock intake plentum, no bypass valve, no boost controller. Stock VF5 is peaking at 7psi, at least i hope it is. Last time this happend I turned around from the road trip I was on... came home, and put a new turbo in.

 

Im thinking, hoping, its my PCV valve.... im gonna replace it on my lunch break and hope to god it fixes it.

Well drove to Kragen to get a new PCV valve.... got the car under boost a few times and no signs of oil burning (well, not as severe as this morning).

 

When i returned to work i replaced the valve. The old valve still moved when shook, and sounded ok... but its been replaced as a precaution. The area directly under the PCV valve was covered in oil, and there was oil everywhere around the area. I noticed the hose comming from the valve was ovalled and wasnt fitting too snug.... so i replaced the lame stock hose clamp with a real screw type clamp.

 

*KNOCK ON WOOD* lets hope that does some good.

Did you get a new OEM valve, or aftermarket? My experience is that the aftermarket ones are crap and will cause oil burning.

Had to do it on my lunch break, so no trips to the dealer for me. Had to use Fram :\
