That's what seperates you from great mates.
Im much like Ryan, dont know a whole heap about engines, Dan is my mechanic but also a great mate, I'd find it very hard to find someone who would make time to help a fellow liner out like Dan has, time and time again not only with my car troubles but a number of others on here, he has gone much much futher then any mechanic i have ever met when it comes to helping someone out.
