I am a self taught wrench head, learned everything I know from looking at a manual and going for it. It wasn't, maybe 4 years before I did my first motor swap, but that was all on Hondas. I know boo me, but now with the xj bug in me, its more fun than ever!!!!!!!!! Nothing beats turning a few wrenches for a few hrs and being proud to say Hell yea I did that..
