Tearing it down

The website went offline due to Hurricane Jeanne (more like forced offline due to no power for 2 days!). This weekend while watching Hurricane Jeanne fly past my back porch windows, I decided to start tearing down the old block. I figured even if the power went out (which it did on and off) I could let the air compressor stay pressurized and work with lanterns (which I did on and off).
This was my first time ever disassembling a block down to removing the crankshaft. I learned two very important things: 1. Label EVERYTHING! 2. Dont even attempt it on an old engine unless you have an air compressor and an impact gun or else risk wasting your time and getting a sore elbow; 3. Make sure you have more than enough room to put everything after you take it apart! When I first started the project I thought I would be able to disassemble everything and remember what bolt goes where. <buzzer sounds> Wrong. As I was getting in to it (I guess I was just excited) I realized I wasn’t following any of the 3 points above and started to forget where bolts went as I was looking for a place to put things down. Didn’t take very long either.
Today I finally finished the disassembly and had some key points to bring up. I think I realized now why my oil always smelled like gasoline. While unbolting the last of 3 of the cyclinder rod bolts the entire piston and rod assembly for each one slid out of the top of the block!! This would obviously mean I had no ring seal on those 3 cylinders. I also noticed when taking off the heads how badly all the valve seals were leaking. Interestingly enough I never had smoke in my exhaust except for maybe a slight puff in the morning when I would start it up. Another interesting note was all the carbon build up on the cylinders. (See below)
After taking it all apart I was seriously surprised that the engine was running as good as it was (I mean up until the day it wouldnt start, which started this whole thing in the first place). I was also very impressed that the engine had lasted so long espcially given its state. It really is impressive that a person can abuse the crap out of these stock engine for so many miles.
UPDATE: When I went to start reassembling the motor about a year later I noticed on some of the bolts where I left oil or grease that it had started (and in some cases succeeded) in eating through the plastic baggys. I recommend using sturdy freezer bags and not the regular sandwich bags if you plan on setting aside your project for some time like me (or even if you dont plan on it). I wish I knew this before because I could have avoided a very sticky, oily mess.
