Help. Hydrolocked Motor?

xMalignancy · Oct 14, 2011

So last week i was driving and without realizing it, i drove through a large puddle. Anyways turns out water got in the intake and the motor died. I didnt hear any loud noises or anything. I coasted out of the puddle and tried to start it again and all it did was 'click'.. and thats all its ever done since. i took all the spark plugs out and still wont turn over. had the starter tested and its fine. im kinda stumped at the moment. Is there anything else i can do? Or is the motor done? Thanks

very good possibility that its hydrolocked

Try jumping the solenoid to turn the starter over?

Turn the engine over by hand. If it still won't rotated, you're FUBAR.

I agree you should try to turn the motor over by hand. But you most likely bent a rod or busted a piston, locking the engine up. Water doesn't like being compressed.

Did any water come out of the plug holes when the plugs were removed? Usually when an engine is hydraulic'd, when you pull the plugs, one or more will have water running out. Something else that could have occured is seizure. Hot engine, pistons at 900 degrees give or take, cylinders expanded due to heat, and add cold water and the cylinder shrinks around that hot piston. Have seen this on ATV's before. Try to turn it by hand before doing anything. Both directions.

When i pulled the plugs there was no water coming out. and also there is no water in the oil.. if that makes a difference. But i try to turn it over by hand and it wont budge.

well..TEAR IT DOWN AND BUILD IT BIGGER!!!

Was there any moisture on any of the spark plugs?
Take all 8 spark plugs out and try to turn it over Clockwise by hand with a long breaker bar. If you can't get it to turn, try lightly bumping it the opposite direction.. but not too hard or else you may loosen the damper bolt.

Highly doubt the motor is hydrolocked... unless the click is coming from inside the motor, in which case would be more like a clunk, it sounds like an electrical problem, I would check the solenoid.

If the engine won't turn over by hand even with the plugs removed, it's more than likely that you have at least two bent connecting rods and the pistons won't move up or down the bore. Pull off the oil pan and take a look from below. Then you'll know if you need to do a complete engine teardown.

I agree.
Probably just shorted out the starter or starter connections.
The car may of stalled because the water suffocated the filter.
Get a huge breaker bar, put it on the balancer bolt and turn the engine.

Hydrolock from a puddle? Did your puddle look like this?

You shouldn't need a breaker bar to turn the engine over. Belt off, plugs out, trans in neutral, you should be able to spin the engine with a regular 1/2" drive ratchet. If not, then yea, you've got a problem.

xMalignancy · Oct 15, 2011

Haha yeah the puddle did kinda look like that. But this week im gonna take the oil pan off and see if i can see anything. I was kinda thinking that it was electrical too but i cant turn it over. I havent tried a breaker bar yet but it wont move with a 1/2 ratchet. I appreciate the help guys.

i agree no way its hrdoblocked. ive worked with hydrolocked motors on boats that either sunk or wee semi submerged and this just doesn't have the symptoms. either you overlooked something when you trried to turn the motor over by hand like neutral and its just an electrical problem or you had a catastrophic failure but i dont think that was due to water ingestion either. it really takes alot of water to cause hydrolocking and the engine will almost always stall long before it becomes locked

xMalignancy · Nov 5, 2011

ok. so there actually WAS water in the oil. a pretty decent amount. idk if that makes a difference cuz it still wont turn over. ive tried marvel mystery in the cylinders and everything. is there anything anything ANYTHING i can try? im about to pull it out but if could get it to run that would be awesome. haha thanks!

If you put a breaker bar on the crank will it spin( I use a breaker bar becaus a ratchet is a pita)? make sure the ignition is off and the spark plugs are out when you do this. The plugs being out will eliminate all the compression so there shouldnt be any resistance when you spin it.

as a matter of physics, water CANNOT be compressed so i'd agree that it doesn't like to either., lol

to the OP have you turned the engine over by hand with the plugs out in neutral? if it won't spin then you have a failure somewhere!!!! It does take quite a lot of water to hydrolock. was this just a puddle or lake? were you idling or high rpm when this happend? either way spin it over by hand. you said the starter was tested, well keep it out of the car when you spin it over by hand (that isn't typically neccessary but if the bendix grossly failed it may be jamming the flywheel, still unklikely)

stykthyn · Nov 5, 2011

even if it is locked. I have been able to squeeze a few extra months out of an engine by just busting it loose with a breaker bar. Not professional by any means, but if this is your only means of transport it may work for you.

xMalignancy · Nov 5, 2011

Yeah i tried the breaker bar with all the plugs out, starter out, and in neutral and nothing.... and i was at about 1100-1300 RPM when it happened but i didnt hear any noise it just kinda shut off.... I guess ill just really try to break it loose since it is my only transportation.

I hate to say it but that isn't gonna work. If you have seizure only maybe u could free it up but have scoring and serious loss of compression, but if rods are bent then it's a gonner!
