Dad and I worked on the GMC all day yesterday, just pulling things apart, cleaning and detailing, oil change, plugs, checking belts, etc. It looks like a different engine already. I'll post up some pics asap.

When we bought the truck the lady told us it needed valve cover gaskets. It was a little wet around the bottoms, .. no big deal. Apparently it had been leaking for a while but it wasn't bad.

Dad pulled the valve covers off and noticed the gaskets were just smashed flat like they had kept tightening them down to try to stop the leak. They tightened them so much that it got the rocker arms too close and they touched the sides of the valve covers .. yes, little piholes in the side of the valve cover! That's why it was leaking. there were about 3 tiny holes in it where the rockers had worked through! Never seen that before.

.. Now, I'm in search of some good stock looking valve covers for it. The driver's side is good, the passenger side (with the oil cap) is the one I need.

We also measured and it is the later rear end housing. So, 71-72 5 lug swap will be much easier.
