I'd go with the leaking FPR before an injector. Very big possibility. Get a pressure gauge on that FPR as soon as possible.

I agree.....either excessive pressure or a leaky fpr...just changed mine...made a big difference in starting and performance.

Correct me if I am wrong, but wouldn't a leaky FPR just leak into the manifold and sit there. A leaky injector would leak into the cylinder and slowly leak past the rings, a more likely scenario I would think.

Yeah Ranger, that'* what I thought, too, but I don't remember what the path is from the FPR vacuum tap to the cylinders, so I couldn't rule out the FPR. If there is a reasonably straight shot from the vacuum tap to an intake port, and if the valve is open, or the valve is a little leaky, then it would be possible to dilute the oil that way. Still, you wouldn't think it would be as easy to dilute the crankcase like that as with a dripping injector.
