One time a long time ago I did some engine work on my car. It was all new and I had no experience beyond basic mechanic stuff. I bought the parts and set in to it. I finished the job and it turns out I had used the wrong gasket material for my water pump. I never saw it coming because I had no prior experience. I took someone's advise for the wrong stuff. I limped it to a mechanic who knew what the **** he was doing.
