been trying to set the timing on my jeep yj 258 and in the process my jeep started making this loud grinding noise when I try and start it. I put a new starter on it and it didnt help so I put the old one back on. The old boy that I bought the jeep off of said he just put a new flywheel in it but I am looking and you can see on the teeth where it has been gringing recently, Teeth still look good but you can tell it is grinding. What do I do now? Anyone wanna make some money, come on over and put this thing in time and fix whatever starting problems i am having.
