It just means I've never done a timing belt replacement. I know it's an exact job, I know what's at stake. However, spending $140 on all the parts I need I found out that the labor would be $250+. That's simply not worth it to me. I'm not new to car repair, I'm just not a mechanic. When I do things to my car it takes me a long time, but I go into it knowing what to do. Nobody goes into their first time replacing a timing belt KNOWING the most effective way of doing it. That being said, this is me asking for what could help me be more effective or generally efficient with my time, before I attempt do do it with the little I already know.
