[QUOTE=Adamhully;40063829]Wouldn't you just need to remove the spark plugs and crank the engine?[/QUOTE]
Hydrolocking often bends the conrod or valves. So no.
Usually stopping something spinning that fast causes problems, big ones.
Depends on if you're idling or revving high? I read hydro locking does not do damage to a car idling, or very little damage?

800 rpm is enough to fuck shit up.
Personally I would never take the chance.
Just dump some techron into the gas tank, and use MAF cleaner if you really think it needs it.
And if you want to clean your throttle body/carburator, take a toothbrush, carb cleaner and do it like you should and make it shine baby.

Depends on the situation too. A car will rarely suffer a hydrolock while just idling - you'd clearly know something was wrong and shut it off beforehand. I've hydrolocked my 7 series a couple of times during cranking, but the crank speed alone isn't really enough to do damage... I have seen someone hit a massive concealed puddle at about 80km/h once though on the motorway, sucked in all that water and ruined their motor - I was travelling behind them at the time.
No matter how many times it happens or for what reasons (fuel, water etc) hydrolocking is still one of my biggest and only fears when working on a motor hahaha, forget everything else!! That's why I'm a little over-cautious when considering sea foaming my car through a vacuum line into the intake. At the end of the day, I just don't think I need it right now.
Its pretty hard to hydrolock a motor from my experience.
Back in my atv days, i had a 2005 Suzuki Kinquad 700. To clean the throttle body and motor, id rev it up high and directly spray carb cleaner into the throttle body until it tried to stall. It was a pretty common thing in the atv world to do that as regular maintenance.
I pretty much did the same when cleaning my iacv on my Impreza.
As long as you know when to stop adding fluid, you wont hydrolock it
