Not sure about the valve guides...these were supposedly new. Here's what it's doin'...

A bit of smoke from time to time at startup. A heavy cloud at full throttle. Both off white in color.

Plugs are fouling very quickly on the driver's side....ALL FOUR OF THEM, but the number 5 is the worst.

It could be all of the above problems...in wich case the motor might be a lost cause. If so the truck will get parked and the motor will be removed and scrapped. Hopefully this won't be the case as I got nuthin' else to drive.
