My car has almost 125000 miles on it and I was wondering if there were any certain parts thatmight be going bad that I should be on the look out for. I've always noticed my engine is super loud. Like if there was a huge fan blowing in the engine bayor something but its not that. The other day I pulled up next to my buddy with an 04 GT and his engine was sooo much quieter. I'm talkin about the engine itself not the exhaust or anything. Hope someone has some ideas on what parts need to be replaced... Thanx a lot.
