SHO ROLLER,
At $81 per hour, that is 13.34 hours. I am guessing he is using the flat rate guide, that is the time it is estimated to take for each job.
The problem is that some of the proceedures, and the time it takes to do them, overlap. For example you have to remove the intake and the valve covers to do the valve lash adjustment, and the valve cover gaskets. Is he going to remove and replace everything twice?
It should not take more than a half an hour to put new valve cover gaskets on before he replaces the valve covers as part of the valve adjustment.
He has it figured for over three hours to replace the valve cover gaskets, assuming his rate is $81 per hour. WTF?
Draining the coolant is part of the intake removal. Is he going to refill the system, then drain it again, to replace the water pump?
The accessory drive belts are already removed for the timing belt replacement. The coolant is already drained for the valve adjustment.
The timing belt covers are already removed, and their replacement is already paid for in the timing belt job, as is the coolant refill in the valve adjustment job.
If you decide to have this mechanic do the work find out what his hourly rate is. Determine how many hours he figures the work will take and discuss the items that overlap, such as the valve cover removal.
The valve covers are already removed to do the valves, so there should be no additional charge to remove them in order to replace the gaskets.
One other possibility would be to adjust his labor bill down to his actual hours. For example if he estimated 13.3 hours and it takes 10 hours, he should not charge you for the additional 3.3 hours.
If he will not concede some of his estimated time, go somewhere else. rangerj
