Welcome to the wonderful world of the do it yerselfer.
I see you posted in the general area. We tend to let topics wander 'off topic', so take alot of time and read the older posts, they are a poorly cataloged gold mine of informantion.
Also; try the search fuction when you come across a problem with your engine, power plant or engine room.
You'll notice a certain GuyFawks. He's very interesting and kind of an unofficial engineering professor.
Some very interesting characters.
Have fun.
