Pop goes the diesel.

While I love this, I can't pass up the opportunity to explain "pop goes the weasel".

The song references the cost of food items in its first verse, followed by "that's the way the money goes, pop goes the weasel". What exactly a weasel was is up for debate; it could be rhyming slang for a coat, or it could mean the pre-electric type of iron that was heated on a stove before use on clothing. In any case, "pop" was slang for pawning an item for money.

That's just advanced individual cylinder block cooling.

Pilot: Mayday mayday mayday, we've had an engine out

Tower: Is it a full or partial engine out?

Pilot: Partially out of the cowling

Please state the nature of the mechanical emergency.

Maybe the little piston just got curious and wanted to see what the outside world was lol about.

External combustion?

Pilot: Commits suicide between day 1 and day 2 of hearings investigating issue

I mean get some blue and white paint and just make it look like R2D2, problem solved!

That’s a herniated piston. NBD, just needs a good push and some duct tape.

Free range cylinder

Isn't... the engine cowling supposed to prevent that sort of thing from occurring?

Starboard engine experienced a spontaneous ejection in one of its internal combustion cylinders. No Bueno.
