is it that hard to put a timing chain on a 4 cylinder? it wasn't on my 91 bmw 318i. it only took a couple hours and the bmw engine bay is a lot tighter then a yj.
I just did the timing belt on my 325e. I had to pull the radiator, shroud, fan, all belts, water pump, and timing covers (obviously, I know), and it still was only 4-5 hours so if he is charging 125 an hour then 600 would be correct. sounds outrageous to me but I do my own work, also
