Hey folks...I'm new to Subaru's and I just purchased a new 2004 WRX, it was a demo and had a dealer installed Prodrive Stage 3 kit installed.
1. Anyway I am wondering are these boxer engines mechanically noisy? Listening to the engine outside at idle it sounds like its going to suck a valve ant moment....
2. So, do these engines need to have routine valve adjustments?
3. Are there replaceable timing belts at say 80 100 thousand miles?
Thanks for any insight..I tried a search but had no specific luck..
