On my '94 pickup 22re. After getting the plenum off I noticed what seemed like gas, oil, and coolant mixing together and making a mess of things inside it and the intake manifold. Make any sense? I'm trying to figure out how it ended up like that. I'll finish the tear-down tomorrow and maybe have something to add. BTW, there is no coolant in the oil.

Also, when I depresserized the fuel lines by running the engine and disconnecting power at the fuel pump I noticed that the engine killed pretty much immediately upon having made the disconnection. I expected it to run for a few seconds. Is this normal?
