Just pop off the valve cover and the car and this board will teach you everything you could want to learn. I am mechanically adept but ignorant under the hood. This board makes all the difference. I even learned how to make the tool (I heated an open end 14mm and bent at the open end to 45 degrees and then trew it in very cold water to temper. I then took my side grinder and narrowed the width of the open end to about 0.2 in. It was not even remotely necessary to have a second bent wrench. As for the spring cover, I used needlenosed vicegrip). It sure feels good to take something like this on and get it done. I have owned and driven all kinds of cars, but nothing has made me want to go out and drive just for the driving quite like this car does. A 5K pound barge that sounds not terribly unlike a peterbilt and I like driving it as much as the MG or the Jag or the SAAB... go figure. And I have definitely never owned anything that was so inviting under the hood.
