Timing

My 100k-mile 318 that came in my Duster slipped a tooth and left me stranded, luckily it was close to home but that thing definitely wasn't starting once the timing chain slipped. The cam sprocket looked like it had been gnawed at by a teething puppy lol...

You can pull off the fuel pump and stick a screwdriver or something in the timing cover and see how much play the chain has.
