pulled a stupid one

Okay, I have to clarify a couple of things.

1) Cracking a fuel line takes the firing load off of a particular piston/rod/journal and will tell: a) which rod is knocking, and b) if the injector is dribbling and causing fuel to enter the combustion chamber prior to set timing (not unlike pre-ignition in a gasoline engine).

2) There is no "splash lubrication" on these engines. The cylinders are lubricated through rifle-drilled passages in the connecting rods via the crankshaft, to the gudgeon (wrist) pins, and through passages in the pistons to the walls. The oil control rings wipe the excess oil back through different passages in the pistons where it returns to the sump.

Actually, I would start by pulling the head, since it will have to come off anyway. And it's easier than the sump, and you can inspect the liner walls.

Splash lubed or spray/slung lube notwithstanding, if the oil was low enough to starve the pump, the crank/conrod's were starved for oil and so were the pistons and liners:) Smoke out the crankcase breather is a symptom of this...

If the OP knows he ran it low on oil, playing with injectors is just delaying the inevitable... and further running in this state may push a still useable crankshaft into the beyond repair/trash bin catagory IMHO...

i guess i will call the dealer guy i bought it from and have it fixed if i can afford it.how much might it cost me?

Agreed. I was just clarifying. :D Splash lubed machinery (not restricted to engines) will usually have a scoop or similar device attached to a rod bearing cap.
