90% sure that my engine is at the end of it's life. Last night whilst driving home from work, it decided to develop a mega loud knock. The knock was coming from the cylinder next to the turbo, and the noise was moving up and down with revs. After about 5 mins of constent unbareable knocking (car idle, as i'd pulled over) though, it decided to just stop, and run fine.
I have absolutly no idea why's it's decided to start this, I rarely bring the car into boost, guess it's just one of those things. I will get it checked out properly, but also going to phone API sometime today for a quote on a 2.5sti engine.
Needless to say, i'm totally gutted.
