Engine Jumped Timing Diagnosis- 2000 Base

[TNT79Bronco]

Upon a little closer inspection, I did find a couple of small, hard brown plastic pieces in the oil sump. I didn’t mention before, but someone may have either drained the oil or been into the bottom end before, because only a couple of quarts of oil came out.

Also, I hooked up a reader. The only code that popped up was P0336. Camshaft position sensor error.

I turned the engine over by hand, both side cam shafts rotate.
