Some final updates
Okay, I now have about 1,000 miles on the (new to me) 1994 LY 30. It's really nice to have working dash A/C. My gal friend loves the real bed. Only real problem seems to be the cracked exhaust manifold. Thinking about SS headers but that will have to wait until I get back to Texas.
Some final thoughts about the old classic 270.... It looks like the shop put the oil filter in upside down and that caused the turbo to fail. As the turbo bearings failed the blades must have hit the housing and part of a fin or bearing got sucked into the engine. This caused a lot of banging (clacking) sound. If the piston and head are okay it could maybe be fixed in the chassis for a few thousand dollars. Maybe the new owner can nail it back together but as for me I have no more nails for it. The shop owner excepted no responsibility.
