A Little Story about a crank bolt

gpgtp_22 · 12-11-2007, 07:42 PM

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.

It did seem that way to be perfectly honest... Another thing I noticed was you said you tried "locking the cam" and then "the belt broke"...

No offence, but this is why I do my own work on motors...

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.

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.

abhattan · 12-14-2007, 06:32 PM

At the dealership, they have all of the right tools, and with the right tools you can do anything. But when your doing a job where you need the car up in a pinch, you have to be a little creative. It's all about turnaround time and cost. You try to keep your customers happy. What I did was a last resort kind of deal. This is not something you would do again. I will now go out and buy the correct tool or get stonger equipment. And by the way, you would be surprised what the dealer would do because your not looking. They know better than anyone that time is money. I've had many teachers that were all A techs at all sorts of dealerships with no less than 25 years of experience tell me stories of unorthodox ways they would get a car going again that the service repair manual doesn't contain. So, please, try to be a little open minded and not so sarcastic of other people's genious
