I will take a real close close up look tomorrow when I down load and
magnify, but that looks like gas wash to me.

Re: Ok guys, here we go. I pulled the head - take a look what I found
If there are no scratches/gouges in the cyl wall, then you got off easy. The
dark area between 2 and 4 show an area where the gasket was leaking a bit,
and would have blown. I would have the head checked for warpage, and
probably shaved before installation. Pop the valve springs off, check the
guides for wear by wiggling the valves. Have the machinst check it too,
chances are they are acceptable. What you really have is bad oil rings. If
you hone the cyl walls, you will get some abrasive in the engine, so you
will have to flush it out with a lot of carb cleaner, and will never get all
of it, but that's what a filter is for. Oil in the cyl raises compression,
so that jug could have tested higher or the same as the others, but I would
not expect a lower reading.
Nice pics, i have to get a good digicam. That "old headbolt" smell, can't
seem to forget it.

That same distinctive burnt oil smell is at the differential caps
too.

I'd be interested in that response and would like to learn how you could
tell that it was a gas wash if it is.
