check ALL your injector lines. myne had tinytiny pin holes in them because of corrosion. once that happens, you have to replace em all. also check your oil. if your wayy high on oil and it looks clear, you have a bad injector and its filling your cylinder with oil and overflowing youroil pan. let me know what you find out

The return line runs up tight under the head behind the fuel filter canister. There's a rubber line that likes to rupture. Real pain in the nuts to replace.

Disregard this post; thought I was in a different forum.

Since it comes and goes, I would suspect the seal in the CP3 may be failing...mine would leak once in a while, usually see the fuel dripping off its wiring harness. but mine never made that much fuel?

It would be worth your time to at least check the injector lines for tightness...I had one vibrate loose, and it created a fuel fountain under hood when the truck was running. but it didn't go away?
