Since the engine is coming apart completely now I took the cylinder head off. I’m not sure what to make of what it looks like. The number 1 and 4 cylinders have a very different look than numbers 2 and 3. You can see this on the top of the pistons as well.
Is this the valves being in bad shape? Perhaps small leaks in the head gasket? I’m sure I’ll find out.
Either way I expect I’ll be rebuilding the head as well, more time and more money for my cheap project.
