Default Turn Over VS Crank

I finally have to ask. Over the years, every once in awhile this question comes to me when reading posts. Over in Tech, there is a thread going where the OP makes the statement, "It turns over but won't crank". The word "crank" is not used up in my neck of the dirt but I have always assumed that crank MEANT turn over! As in old style "cranking". Is it a regional thing and there are two interpretations to "crank" south of the 49th.? Comments please.

In my Opinion Turn over meant Start/Run no matter how poorly, Crack thing's move but don't Run or not running yet.

turnover simply means the crankshaft is turning

Crank seems to have multiple meanings depending on who you ask
In the context the OP mentions it means start or run
as already mentioned some give it the same meaning as turnover

not sure you will ever get agreement on what crank means

CRANK (turn over), NO-CRANK (don't turn over), CRANK - NO START (won't run) often get twisted in the threads. I sometimes have to read the threads a couple times to try and sort!

I think the FSM mentions, CRANK, NO CRANK, CRANK - DOES NOT RUN and maybe even SLOW CRANK

**I've a friend that uses "won't turn over" as meaning the engine is "locked/seized" - then CRANK etc!

My opinion is cranking is turning over but not running. If it won't turn-over that means no rotation.

Color me guilty on this one. I say turn over to mean the engine is rotating but "crank" means "run". Now that I think about it I see how that can be very confusing. Time to change a habit!

My grandpa had a hand cranked tractor, and you'd better learn real quick that there was a BIG difference between "cranking" and "running"! Slow learners would end up with a broken arm!!

Nope. Quite literally, this is where the term "cranking" or "Crank" came from:




As you can see...the guys is using a hand crank to...ahem, "crank" or turn over the engine's crank shaft to get ignition. Once ignition and combustion occurs...it is "firing" (that is, combustion is happening in the cylinders) and once stable, regular, sustainable "firing" is happening...then it is "running".

Getting these terms right helps us, help you.

BTW, the car in the .gif is a Buick.

I always use "crank" as turning the motor with the starter. I saw an old WWII movie once where they said "They turn over the tank motors for 30 minutes every morning" which meant they ran the engines.

I guess the script writers were a bit misguided too according to the consensus.
