i was driving and my cold air intake bracket broke when i was driving through a low water bridge and it sucked water through it. now it will not start i was just wondering if any of you could tell me how to get the water out and get it to start
 
pull the spark plugs and all so the wire harness off the coil so you have no spark
then crank it over all water pumps out

later

You hydrolocked the motor, if you were at anything above 1500 or so rpm, consider the motor thrashed and blown-up like a loitering iraqi.

Water doesnt compress, once injected into the cyl. it will prevent the pistons from going up, which will break rods and bend cranks.
 
i finally got it started let it run for five minutes to let the engine flush work drained it and put an oil change in it and it still knocks it's not a loud knock but it's a fast sounding knock can anybody tell me what it could be thanks
 
ive heard of 4x4's offroading through mud and sucking up water. They change the oil, take plugs and crank the engine to get the water out..

Good percentage of them havent harmed or bent anything in their motors at all so there IS still hope.
 
i've got all the water out i was just wondering what could be wrong someone told me it was the crank bearing or rod bearing could that be true thanks for all replys
 
I dont have first hand experience with sucking up water BUT i think if you looked up
"Hydrolocked motor" you would find many websites with related info.

my motor is not hydrolocked it still starts but it knocks

Your motor hydrolocked. Yeah, you got the water back out and it starts now, but you hydrolocked your motor.

The knocking sound is probably rod knock. You can believe what you want, but prepare yourself for the worst.
 
THAT close to the ground, how high was the water?? Why hasn't anyone said the obvious?? DO NOT DRIVE THROUGH WATER THAT DEEP! Jeez :thumbdown :thumbdown :thumbdown Take the bottom end apart and inspect.
 
cmon guys, just because he hears a knock DOESNT mean his motor is done for and he needs a rebuild.


First take apart your motor and INSPECT everything. THis is exactly why i asked you to search "hydrolocked motor" because it will show you others experiences when they take apart their motors and trust me, many people have pictures.

Annnd while you have everything apart and down there you might as well do a rebuild :)
 
i just find it amazing that out of all these geniuses no one asked if the knock varied speed with rpm change across the whole rpm band. as if the knock is at the same speed as the crank and changes rpm perfectly with the crank.

:rolleyes:
It doesn't take a rocket scientist to add 2 and 2 and get 4 -

He sucked water into his engine. It died. THE ENGINE HYDROLOCKED. If you have ANY experience with such a thing, you know the result. If not, search before you prattle off at the mouth about us "geniuses" not asking questions.
Common sense tells you if he hydrolocked the friggin' motor and now it's knocking, he BROKE IT.
 
*raises hand to speak*

Acutally, hydrolocking an engine does NOT automatically qualify it for the scrap heap, or a rebuild.

My ECU recently went out, causing the injectors to just "pour" gas into the cylindars. After trying to start the car, several times, it hydolocked. Removed the plug, got the the engine freed, turned by hand a few times, spit raw gas out of the tail pipe, changed the oil, cuz it's full of gas now too, added a new ECU to help control the flow of the petrol, and voila, engine running solid again. No knocks, pings or otherwise unwanted sounds.

NOW, granted, hydrolock can be a BAD BAD BAD thing, but doesn't always imply death.

What I would suggest is checking for a bent rod, or crankshaft. Either of those COULD be causing the "knock" that you are hearing.

First of all, you didnt Hydrolock your motor, because you locked it with gasoline, not water(h20 = hydro).

Second, Gas can compress, whereas water cannot, therefore it didnt put as much pressure on the rods/crank.

Third, Im assuming your car was idling, in which case there isnt enough piston velocity to break anything, itll simply stall, just like when you loose a timing belt at idle, your valves are fine.

It only takes common sense to come to determine the fate of this engine. Just Lay out the facts you know.

Order of Events:
1)Before driving through water-Engine ran good and sounded good
2)Drive though water and engine stops.
3)After draining oil and pumping out water (first clue) engine starts, runs and knocks.


Other Valuable Information:
1)H2O does not compress.
2)Rods and other internal engine components will bend/break before water compresses. (see info #1)


Correction:
1)Tear down and inspect/rebuild or just replace.
