A Little Story about a crank bolt
 

I was replacing a timing belt on a Honda Accord when I couldn't get the crank bolt out. This is a common issue with Honda motors. And the compressor I have doesn't help. I tried 3 different guns and tried to jam the cam. The belt eventually broke and the bottom end was free. We even tried to jam the flywheel with a prybar and couldn't do it. We aren't the biggest people. So we took out the spark plugs, filled the cylinders with water, and removed the cam so all of the valves are closed. Then we attached the breaker bar to the socket with a decent size extension and turned. The crank only turned about a quarter of an inch if that and the bolt was loosened. So just incase you ever in a position where you can't get your crank bolt out. You can use water! Oh, the Honda engines rotate counterclockwise, same direction the bolt is being turned while trying to be loosened. So we could do the lock it with breaker bar and key the engine.

that sounds like something i would never attempt...
leave a breaker bar in the cam gears and crank? ur just askin for trouble when you do that...

I never said it was in the cam gear. You attach the socket and breaker bar to the CRANK bolt and hold it up to the chassis somehow and then crank. the torque will turn the bolt out. Completely safe if your engine normaly rotates clockwise. Not if it rotates counter clockwise.

NEVER TRY THIS! This is one of the worst ideas I have ever heard and I hope nobody ever tries this for the sake of your engine. First off water should never be in your combustion chamber period. Second have you ever of hydrolocking. If not here is a definition from wikipedia.

In automotive terminology, a hydrolock (short for hydraulic lock) is the immobilization of an engine's pistons by a liquid (usually water, hence the prefix "hydro-"). Hydrolocking occurs when liquid fills a cylinder on the intake stroke and, due to the incompressibility of a liquid, makes the compression stroke impossible. This, in turn, prevents the entire engine from turning, and can cause significant engine damage if one attempts to forcibly turn over or start the engine. Typically, connecting rods will be bent, making the engine uneconomical to repair.

You are very lucky you did not ruin that engine! Make sure you aren't suggesting repair methods that could potentially destroy someones engine. Never use water.

I am not recommending this to anyone. The amount of torque being applied by myself as opposed to the initial hit from a starter is low enough that the rods wil not be damaged. And the engine is not rotating at any speed, so there is no build up of energy that has no where to go but to the rods, in the case of a running engine that just swallowed some water. You should not condem the strategy of some just because you do not understand the theory. And as far as water being in the combustion chamber, have you ever heard of methanol or water injection? This is small oamounts of a liquid that is being injected with the air/fuel mixture into the combustion chamber. By rotating the engine a couple of times manually, the water is pushed out. Then you simply blow out any existing water and drop a cap of oil in the chamber. Don't get so worked up.

Your silly, and probably have NOT turned as many wrenches over the 30 years I've been a professional auto tech.

This water idea is a valid one. And does work. The Hydrolock you are talking about will NEVER even come into play with the JOB the fellow is describing.

More research on you part before 'spouting off' is needed.

Thank You.

Hey its your engine...do whatever you want

looks like somebody spoke too soon, and got proven wrong:gtfo:

Yeah you are right putting water in your cylinders to keep the engine from turning over is a great repair procedure. That is what they do at all of the dealerships when they have a stuck crank bolt right? I thought I saw that in the service manual somewhere, must have just slipped my mind.
