All of you guys..been in my position:

You are sooooo fortunate to live in these times of online information. Back in 1972 when I was tearing apart my first engine, I did not have a mentor, big manuals, videos, only car mags. I did have a Motors Manual, which helped a lot. Like everyone else has mentioned, dig in and start taking things apart. Mark where they go, or better yet, shoot some pics of what you are working on. There is infinite help online and also here in this forum. Don't be scared, just use care and be meticulous. You can do it!

I literally can't fathom the thought of learning this stuff without the internet.
