Unfortunately, it's about as serious as internal engine damage can get. The connecting rods do just that... they connect the crankshaft to the piston and move up and down in response to the internal combustion. The engine has to be torn down and the rod replaced. That, along with the bearing in the lower end where it connects to the crank. The crank, itself may have suffered damage as well. Additionally, there may have been damage to the intake or exhaust valves.... no way of knowing until the engine is disassembled.
Often times,in cases like yours (at least here in the U.S., it may be cheaper to by a short block... That's the major part of an engine including the crank, pistons but maybe without the head. The starter, alternator, fuel pump, etc, are removed from your existing engine and applied to the new one... hence the term short block ... again, I'm speaking from experience here in the U.S., but most engines are, more or less, similar. But, for what it's worth, Good luck!

As Clanad says, doom & gloom I`m afraid. The cost of a new or exchange (if available) engine plus removal & fitting will be high. So high for some cars, newish Jaguars for example, that it is uneconomic & the car goes for scrap!

scrap it

Hi,
After reading the last posts I agree that the cost COULD be major, BUT would seriously ask a local garage how much its going to cost. There are ALOT of factors to take into place including What type of engine it is and what make of car. Some manafactures allow sufficiant enough gap between the "head" and "block" incase of such incident. My advice would be :- DONT SCRAP IT YET GET IT CHECKED! Good Luck

its sucked in water it is partially seized, the garage would have to take the engine out, strip it down, repair the damage which will probably include broken pistons, it is cheaper to buy another engine.

it may be possible to claim on your insurance, seen it done a few times.
Even though its self inflicted ins. co,s do pay out... !!

clanad is correct but if your car is not old think about a second hand engine. But don't forget to get the price first and the price of a rebuild of your scrap engine. I've done a couple of re-build they do spiral out of control.

Hydraulic lock - not seizure i suspect.

Did i miss the bit about the broken con rod diagnosis....

Has a mechanic had the top end off, or the screwdriver at TDC ? looking for the missing piston.

hydraulic lock?? maybe youll find the engine wont turn over as the con rod is bent like a banana!! nothing to do with a hydraulic lock!!and by the way taking the head off will only POSSIBLY reveal a little, you wont be able to see any damage that may be below the piston and its not automtic that the piston is gone maybe just a new conrod and gudgeon pin but the labour will kill it in my view

[cazzz1975]

hydraulic lock will take the cam shaft not the con rod

lol @ hydraulic lock...
