Engine Waterlocked

so wednesday morning i was forced over from the center lane to the outter lane on the highway, where there was some seriously deep water 1-2 feet. after recovering from the swerve, the engine rightfully seized up from the consumption of water through the AEM CAI.

due to having to get to work, the car was pushed to a nearby lot and picked up yesterday afternoon. i had obligations so i could not get to the issue last night either.

today when i get home, i will be removing the spark plugs and turning the motor over to remove any water from the valves. ( i was also told to spray WD-40 into the valves after removing plugs for water displacement) someone confirm that please if possible.

my question is, what else besides ridding the valves of water, and checking my oil for a milky color should i do to ensure this thing gets started back up safely.

is it really bad that it has gone over a day with water in it? i really wanted to get to it earlier but just couldnt. im hoping no real damage was done, the car stalled out almost immediately after inhaling the water, and was not ran at all afterwards. the car wont even try to turn over at the moment, so i may have to turn it by way of socket and ratchet.

any extra input would be greatly appreciated, i really dont want to lose this car to a little bit of water.

Leak down test and compression test. Hope you don't have a bent valve.

I got lucky on mine, i used a compressor to blow the water out of the intake manifold and used a vacuum to suck up any water in the engine. My started had to be replaced since it got burnt out from starting the car and replaced my battery since that died on me too. hope your car starts running again. after waterlocking my engine i'm scared of the rain now lol

I'm not sure of the WD-40 but Seafoam should help burn the water off

Definitely unfortunate to read about ... No advice here, but I truly hope the engine can be restored

A good reason not to get a CAI. If your motor survived this one, I would ditch the CAI. It's just not worth it, unless you can leave the car parked when there's bad weather. There is flooding all over Louisiana right now.

Get an K&N intake. It can convert to short ram during the rainy seasons and CAI for the summers.

I hyrdolocked my motor once. Took my wheel off, put a breaker bar on the crank... and it wasn't moving anywhere, lol.


So, good luck!

That sucks. I rather have a bent valve than further mechanical damage. Why dont you convert over to short ram for the winter season?

Here is how I saved my engine when it got hydrolocked.

1. Take the spark plugs out
2. Buy a can of fogging oil and spray it down each spark plug hole
3. Crank it over for a second or two and watch the geyser of water shoot out
4. Spray more fogging oil down the holes.
5. Repeat until all the water is out.
6. Put brand new spark plugs in. DON'T TRY TO START THE CAR YET
7. Change the oil
8. NOW try to start the car. It took me several attempts to get it started. If it starts, let it run for 5 min in park.
9. Change oil again.
10. Let it run for an hour or two
11. Change the oil again
12. Drive it around for 50-100 miles
13. Change the oil again

I've put 15,000 miles on my engine since it was hydrolocked and she is still running strong. There is a good chance your engine is a goner but you might get lucky like I did.

The last step is to take out that CAI and replace it with a SRI!

This is good advice. Had an older Accord that I hydrolocked, and when I took my plugs out, the first one had a stream of water run out for about 5-7 seconds, I assume it was the one the intake valves were open to. The only thing different I did was separate the water from the oil and poured the old oil in for the first start up. No sense dumping new oil in it until you know its going to turn over and run normally.

After I got it running, I put another 30k on it before I sold it, no issues.

And its not valves that bend in a hydrolock situation, its the rods. You'll know pretty quickly if your motor is f'd up.

Dang, that sucks. Hope you can get it running. I'm gonna install the K&N apollo kit when it arrives and have the tube run down like a CAI. I guess I'll be disconnecting it when it rains and run it SRI heh
