Well, I don't want to drop the money on it if I don't know it's necessary. I bought it used a few months ago and for all I know it's already had them replaced. It'd be a shame to spend a grand without needing to, especially considering I'm your typical broke college student.
The Subie dealership I take it to know how paranoid I am. I've been going to them for a long time, they've never once tried to rip me off and their prices are very reasonable. I trust them to be knowledgeable enough to find the problem. And if the engine blows, well, then, I guess I gotta find another engine.
Wish I knew more about engines and cars in general so I could do all this stuff myself. This forum has been an incredible help already, though. I've practically tripled my knowledge of engines and random little things on the car since I got here, but I wouldn't say I'm comfortable doing anything on my own.
