(1) Answer
We also just had our timing chain replaced and cam phasers. First mechanic turned down the work. Second mechanic said some mechanics will not attempt to reset timing chains cause they r so tricky/aggravating to get lined up. You might need to take it to someone else who has had a little more experience or feels more comfortable replacing those. We worked with a master mechanic. The cams were pretty expensive to replace. Hope that helps.
