I have an '02 WRX wagon that has a number of problems:
1) The timing belt idler froze up...
2) ...which chewed up the timing belt ...
3) ...busted the gears...
4)...and bent all my valves
Just a little bit of history about me and cars. I'd call myself a car owner educated in the basics; I do my own oil changes, coolant, know how my fuses work, and installed a block heater….etc.), but beyond that I’m a bit at the mercy of mechanics. I don’t much know the lingo. Originally got the car with my fiancé (now ex) who wanted to do more with it, but now I just really enjoy it as a fun car to drive. I got it used in '07 and don't know what mods have been done on it (I know the wheels are after market, but beyond that nothing).
My questions are:
1) At a shop, what should I expect for labor hours for the replacing of the whole timing belt mechanism (idlers, gears, belt….etc.)?
2) What should I expect for labor hours for the valve replacement?
3) What details are actually involved in replacing the valves and doing a good thorough job? (are new valves just put in place and that’s it?.... or?)
4) How would a good mechanic go about making sure everything is in good working order once the job is completely? In other words, beyond just taking the car for a few test drives are there typical procedures that a good mechanic goes through to make sure an engine that was disassembled has been put back together in good working order?
I think that’s all the questions I have for now. Thanks so much for your help .
