It finally warmed up enough that I could tackle the engine bay. Took out a lot of AC parts and well, everything else too. Rust is worse on the inside than i thought, passenger floor is paper thin. It looks like it was leaking in there so thats why they went crazy with the spray foam. Oil drain bolt was just about completely rounded off, not sure how I'm gonna get it off. PB blaster was a livesaver on the AC compressor bracket, crazy how much that thing weighs.
Next on the to-do list is bug spray for the roaches in cab, they were living under the 8(!) floor mats. Then get the engine out and see what I'm workin with. A quick glance under the valve cover, without too much poking around, was promising. I've seen much worse is cars 1/3rd it's age.
