Thanks for the information. He will be replacing the chain, tensioners and all of the parts associated with the system. So how long should the repair take for an experienced mechanic?

 

Not sure how long it takes, but make absolutely sure that the new 4-4 chain is put in. (Some people call it the 1-2-1/2-2 chain; the key is that there are 4 links at each step, not an alternation between 3 and 4 links, like the old chain.) I've heard that a few of the old 3-4 chains are still floating around. To pay for all this, only to get another badly-designed chain would ... well ... be sub-optimal.

If the mechanic is cool, send him the link to the RRE description and/or bring him a print-out from the shop manual. My experience is that the better mechanics might not want to admit to using a manual, but like to have it around to take a look at. My trick the few times I had a car worked on was to hand it over, saying "oh, hey, I brought this along in case you don't have the torque-specs." In two cases, I got the print-out back with some smudged finger-prints.
