Yeah, guess I should go back in after that EGR. you talked me into it.

I'm the guy recovering from that deer hit, and I've got several little this and thats to put back together. Maybe this weekend i'll knock off a few from my list.

I DID just buy that (wagon) spoiler at the JY at lunch today for 20 smackers. Needless expense, maybe I can tell my wife it will improve our gas mileage! It's kind silver, not white. I might put it on as is, Looks cool. Easy removal. Trying to save up some bucks for a new motorcycle, maybe I should ebay it.

Sorry, it's not very likely. The EGR uses vacuum to operate. The valve allows the engine to suck in exhaust gas to dilute the fuel air mix during mid throttle operation.

With the smoking condition you have more blowby than the PCV system can handle and the excess has to go someplace. That is a lot of blowby though and there might still be a problem someplace where you're not getting the proper amount of vacuum to the PCV black box to draw off the vapors.

Anybody know what the torque spec is for the EGR valve bolts? I can't seem to find it.
