So I'm going to bite the bullet and have my timing chain replaced as preventive measure. Also the necessary related parts (tensioner, guides, whatever).

I expected to pay about $200 for parts but my independent mechanic says around $400 for the parts. That was unsettling. I'm wondering what the labor will be.

Can anyone give me comparisons? I trust this fellow but didn't expect the cost to be so high.
