So I tore the thing apart because a compression test revealed no compression in Cylinder #3. I must have floated a valve that made contact with the piston. The #3 exhaust valve is bent.
I could likely fix this with a $10 valve and some new valve springs, then again I have hated this thing so much lately that I hope to fix it for the long haul....
I'm hoping I don't get burned, the yard says 77k miles, and was running good, they had already started removing it when I got there. They bought the lot of 3 trucks at auction just for this motor - through a pricing error I got it cheaper then they wanted to let it go. They are pulling it for me next week. The trucks came from a steel factory, this likely was a yard truck with the low miles. I'm guessing lots of idling. The others had 200k, but the engines were cleaner LOL

Well gotta figure some items out... My engine was originally sat high in the engine bay, and this one still sits high. I think I can make the truck intake work. The evap valve thing may have to be deleted...
Mocked in
Back on the stand for a cleaning and gasket refresh, This truck was a steel mill truck, it's filthy.
Looks pretty dirty for 77k
1/2" deep under the intake
I couldn't believe that local shops wanted $100+ more for a gasket kit then Summit. I'm at a standstill now until I get more time. Going to do gaskets and plugs, clean out the intake where oil got in when the engine laid on it's side, and attempt to get the valve covers clean. The oil is basically varnished on.
I was buying a 'low mileage' engine to avoid all this dirt and grime.
Gaskets, manifold bolts, oil cooler block off, paint, and TV setup arrived. Plugs, fuel line, AN fittings and starter too.
Hopefully I can go to town on it this weekend, the computer has been shipped for its reflash as well.
