Rust and grease
When we started this project we thought there would be rust to deal with. I assumed I would use my wit and skill and strength to remove it or convert it from the parts. I understood the concept of using a wire brush and a wire wheel to scrub the rust away. We really have no idea what we have gotten into. My engine is still not turning with a wrench, but I don't care because when I hoist it out I will drop the oil pan, remove the crank, and tap-a-tap the pistons out the bottom. One way or another, those guys are coming out of there. My problem is actually that the transmission bolts are stuck to the mount. And the mount bolts are stuck to the cross member. And the cross member bolts are stuck to the frame. So - while I wait for the miracle of penetrating oil and seismic activity to do its job - or until I break down and buy an impact wrench - there is LOTS of stuff to clean. I went after my grease covered valve covers. I used my homemade 3D printed scrapers on them. Grease is amazin...
