    White smoke= water or coolant in the combustion chamber. probally a blown head gasket or worse.

    Could be an injector too. Try testing or replacing all the injectors before you do a head gasket.

    The butterfly valve in the left exhaust manifold may be stuck, I think its called the EPR valve or something. Anyway, youll have to take the pipe off the manifold to see for sure unless somebody knows a way to see if its stuck with the pipe still on. This would explain the low power cause of a massive exhaust restriction, and the white smoke is unburnt fuel, possbibly because that side is not getting enough air to properly burn the fuel due to the cylinders staying filled with exhaust. If its not stuck then I would look at fuel timing or a blown head gasket, possibly other things.

    The way to tell if it's worse then a head gasket is if you pull the dipstick, not filler neck! and watch for belching white smoke! If so, probable cracked block!! /forums/images/icons/crazy.gif /forums/images/icons/blush.gif IF no smoke coming from bottom of engine, blown head gasket would be my next explination, but always try the esier solutions first!
