************************Engine Rebuild**********************
Here are some pictures of my current engine rebuild:
This is what was happening between #1 and #2 cylinders. The center of the picture is a groove cut in the head. My father spoke with a freind who has been working on cars for a long time and he said that JB Weld has worked for him in the past. We'll see if it does. Stay tuned for more overhaul pictures!

Valve Lapping
(My dad lapping the valves)
This engine had very low compression in all cylinders as tested before we tore it down. I figured the piston rings were broken or worn out and the valves needed to be re-seated. After teardown, we noticed the person who last assembled this engine, had installed the piston rings with the gaps lined up, and this left a ridge up and down the inside of the cylinder wall. All of the valves were deteriorated. The intake valves were not as bad off as the exhaust vaves. Cylinders 2 and 3 exhaust valves were eroding into a triangular shape. So, we checked the valve guides and stems which were in good shape. We then hand-lapped all of the valves until they had a uniform contact area between the valve and valve seat. We then installed new valve stem seals and springs, then continued to reassemble the head. Lapping valves is old school and is something you should know how to do even with all of the modern ways of grinding valves.
New coat of paint on the block!
(don't freak out, I am removing paint wherever something mounts to the block.)
!Update!: Well it is the middle of winter here in AK, and one problem after another, and we still do not have the truck running yet. It is in the truck and we are between third and home.
