Hydrostatic lock is a failure of the internal combustion engine, where the unit can’t run due to fluid entering the combustion chamber above the piston and preventing it from completing its cycle.

While the usual fuel-air mixture is compressible, allowing the piston to perform its reciprocation movement inside the cylinder, liquids are extremely difficult to compress, which means the affected piston(s) will come to a stop on the upstroke.

What can cause hydrolocking

Before we start talking about this unpleasant issue, we have to explain that water reaching the intake of your engine is not the only hydrolock cause. Alas, this can also occur due to engine coolant entering the combustion chamber (a blown head gasket causes this). Malfunctioning injectors or carburetors can also allow liquid fuel to enter the cylinder.

The Damage, in painful details

The effects hydrostatic locking can have on your powerplant depend on the state of the engine at the time the water enters the combustion chamber. If an unit hydrolocks when idling, it will normally stop and will not allow you top bring it back to life using just the starter motor. This is happiest case, where you might not experience any damage at all.

Unfortunately, if an engine hydrolocks when being revved, the consequences can be dire. Depending on the height level of your intake and the depth of the water, as well as on the various on-site parameters, the amount of liquid that enters the engine can reach one or more cylinders.

You can experience a case where a single piston hydrolocks, while the others provide enough power to keep the engine running for a while. However, when hydrostatic locking occurs at speed, the unit will usually come to an abrupt stop.

Generally, when an engine hydrolocks at speed, the force of the camshaft pushing bends the piston rods, which are folded under the piston above them. While the crankcase or the heads can be ruined in the process and the crankshaft bearings destroyed, the shock can even cause cracks in the engine block.

GAZZUZZ:
New head gasket installed, oil pump/balance shaft installed, timing chain installed. Note there are timing marks for the balance shaft/oil pump.

Every other thing installed in reverse, and engine is sitting on the floor waiting to be installed back in the engine bay.

Work continues on monday morning.

You will notice that the replacement piston is sludge free.

Boss how did it go, following keenly

GAZZUZZ:


No vehicle history, engine started fine, but mild rattle at 3000 rpm that disappears ad 4000rpm. Possible crankshaft failure, possible bearing failure, possible balance shaft failure.

Vehicle is being used and was supposed to come back yesterday for an inspection, but driver seems to have a mind of his own.

Mr Gazzuz, (1) I drive a Honda Accord 03 but recently, i noticed the gear malfunction by not selecting properly. Mostly if i put on A/C in traffick, it will engage but forcefully transmit with high jack to next. (2) Is there other ATF to service this accord transmission apart from ATF DW1?
Thanks

Brake disk repair, involves filling of few mm of brake disk material to make it even and smooth again.

Below are before and after pictures.

GAZZUZZ:
Been really busy, and have not been updating with pictures.

Jetta has been fixed steering is perfect.

Jaguar battery ran down and is being charged so work done can be tested.

Other vehicles are for nairalanders and they specifically instructed no posting of their vehicles on NL, so I am respecting their wishes.


Should be in delta and ph tommorow, pics of work done there will be posted.

Boss Gazzuzz, is there any reliable Mechanic in Warri you can recommend?
