timing belt, water pump, pcv

[bigjackio]

I'm going to have my timing belt replaced for the first time, at 94xxx miles. I plan to use the following volvo parts:

- timing belt, idler pulley, and tensioner (these come in volvo's "kit")
- water pump & the gasket volvo includes
- serpentine (or drive) belt

?'s:

1. Any other timing components I should replace?

2. Should crank seal & cam seals be replaced even if they aren't leaking? What is their life expectancy?

3. Since replacing the Piston Cooling Valve requires removing timing belt, tensioner, & pulley, should I go ahead and have a new PCV installed now? Mine has never been cleaned.

4. Anything else that should be done while they are in that part of the engine? I don't want to miss something that is near the end of its life expectancy & have to pay for the same labor again anytime soon.

5. Any good reasons to use the dealer over a reputable, independent shop? Does replacing these parts on my volvo differ much from other cars?

Please Help! I'm afraid to drive the car because of horror stories I've read/heard about timing belt failures. If anyone out there can comment on any of my questions, I'd really appreciate it. I need to get this car to a shop asap, but don't want to trust them to tell me all the should be done. Thanks in advance.
