The Official "How Not To" Thread

Do not test fire a 340 recently placed in a car with a painted engine compartment but the rest of the body is in "sanded with 400 and ready to paint" primer IF the oil pressure senor has not been re-installed. There is a pretty good chance that the oil will soak into the primer, and you will be forced to do a lot of sanding and re-priming. I of course never did that, but I guess it could happen. LOL. Seriously, it took me several weeks to recover from that bonehead mistake. But the engine did run pretty well.
