Yeah option B is not an option after the number of youtube videos I've seen of things flying into the back of the pull vehicle when they finally let loose. That, and the fact that we had a downpour last night which would have turned the front yard into a mudbog-a-palooza-fest for all the neighbors to enjoy.

Finished the autopsy today on the old engine. Here's some photos.
Pulled the heads off. Some of the chambers have the normal cracks between the valves. GM considered this "normal" wear in their TSB.

The valve covers were immaculate. (The black painted one is the NOS cover replaced during the headgasket job in 2013)
Camshaft and lifters looked nice - normal wear. Looks like the cam bearings were showing copper on all of them.

The upper halves of the main bearings all were flaking like the lower halves.
You can see the difference in the main cap mating area where the crack goes through the bolt hole. Looks like most of this stuff is going to the scrapman in the next few weeks. The old mill had a good life. Gonna be sad to see the big ol' hunk of iron go. Last edited by njsteve; 07-23-2017 at 08:19 PM.
