I have a 2001 wrangler 4.0, engine turns over will not start. I removed the camshaft sensor and the head of the synchronizer is broke in pieces. What could cause this?
Damn that broken part is hard to find. The Mopar parts guide says it's p/n 4897023 but that only brings up the top sensor itself, not what is broken. Not even Rockauto.com shows it.
I'd call Davey's at https://daveysjeeps.com/ who has Jeeps in the back lot they can pull it out of. That p/n doesn't show up in a Search there but they should be able to pull one for you.
