Well, not a giant setback, more of an annoying setback. Somehow I have a good size dent in the oil pan, possibly from transporting the engine and maybe a jack pushing it up at one point. That's all I could possibly picture. At any rate, I realized quickly there was no clearance between the pickup screen and the floor of the pan. Rather than kill the engine, I have to pull the motor to replace the pan (I hate in truck pan pulls). So a new pan is on the way. Trying to not get bit by the while Im here bug!!
