Default oh... my... god.. mother nature hates me

Well was driving home from a movie last nite, and then i guess while i was in the movie it started to rain, pretty bad. So i come out to a hell of a storm. I was hopeing that i would be fine so i decided to drive, especially when i was not too far away from home. So iam driveing, and i figured it would be safer to take back roads home instead of the freeway, cause i honestly dont trust these shittenzas. So as iam takeing backroads, going 25-30 in a 45 trying to look out for stuff on the road, and puddles. well all of a sudden at the last second i see a giant puddle, and i slam on my brakes, well by then it was too late and i was heading right for it, so i see some good splash comeing from the sides, then see a splash in the front and then comes smoke... What do you know my car shuts off. So i step out and water is up to my ankle atleast. I put my car out of the mini lake and throw on the hazards... I thought right away.. o god i hydrolocked it. I take off my intake tubeing to check i see some water spots but nothing pouring out. I look into the intake manifold hole and see some water as well. So obviously some water got sucked in...
Oh and for the record, i am stock, besides my body kit, stock instake, stock exhaust, stock cats, etc.

So now my car is sitting there, unable to start, and i am clueless what to do. Iam gonna give it another day to rest and try to hopefully dry out, and then if still not starting gonna try and take it to Nissan and see what they say. Anyone think this could be covered under warranty? I really would rather not start up another claim with my insurance right after the little coyote incident.
Anyone got any pointers or ideas of what is wrong? Iam hopeing not hydrolocked, but not gonna deny the fact that it is very likely.

Holy crikey man, that really, really, REALLY sucks.

Just out of curiosity, what made you think that back roads would be better? I know the rate of traffic would be slower, however, freeways usually don't experience the rapid changes in elevation or size like back roads..therefore, mini lakes don't pop up.

As for the warranty issue, I highly doubt it will be covered; however, it never, ever hurts to try!

First off, relax. Your car is fine. you are not hydrolocked. Your car would stall out LONG before you actually sucked enough water UP your intake pipe to cause it to be hydrolocked. You most likely just got some wiring wet. Let the car sit for a day and it will start up with a puff or two of smoke.

All that hydrolock BS that floats around the net is just that, BS. I ran my strat coupe with a CAI through a 1.5' puddle, COMPLETELY submerged the filter and the car stalled out. I coasted through the puddle, started the car back up and went on my way.

Anyone actually know a person that has hydrolocked an engine going through a puddle?

In this case, if your intake is stock, the puddle would have to be deep enough to sink the car up to the windows. Even if you did run into a puddle like this, your engine would have to keep running, without any air intake, long enough to form suction strong enough to suck water up the intake tube into the motor. That is just not going to happen. Sorry

It's not that easy to hydrolock. If your stock, your intake should be sitting pretty high, and water shouldn't be able to go directly to your intake, bumper, hood, etc. Even if it did, you need to consume a lot of water, one puddle splash is not enough, all of it cant penetrate through the box(filter) and travel up the piping into the intake manifold.

On the side note, how'd you manage to get the car home?

Dude, call road side assistance and get your car home. Then call your dealer and tell them it shut off while you were driving home in heavy rain. If the refuse coverage, find out if the city is responsible for maitance on the road. If so get them to cover it. Worse case scenario, take Nissan to small claims court.

Ok say what IF i had a CAI, and went through this puddle, would i have hydrolocked then? The second i went through the puddle it shut down, and since then i have not been able to start my car up. It has sat for a day now and nothing. I will check tomorrow and hopefully something will happen and it will be fine. But why is it not starting now? Eletrical? What happens if it does not start tomorrow? And why was there some water spots in my intake tubeing?

Water is fine to go into the motor - FI guys run water/meth injection - it's just a matter of amount. It would take about a 1/2 to a full cup of water to hydrolock the motor, so "some water spots" are nothing

Even if you had a CAI I would bet big $ you're not hydrolocked. The car stalling is exactly would should happen if the intake filter was completely submerged. It cuts the air to the motor. Does the car turn over? Turn over hard? Does it click? Does it do nothing? If your motor was truelly hydrolocked, it would try to turn over, but wouldn't. You would hear the starter try to engage and then nothing. The motor would be basically seized up.

Put your stock ish back on and take it to the dealer. If you engine is stock I see them completing repairs if any under warranty.

Default Try this

TRY THIS, it worked for me, I had an Injen CAI on my 3" dropped Integra last fall and went into at least 1 foot of water on a highway entrance ramp, the car stalled out, I was **** scared, as I had never gone through it before. ANYWAY, this fixed it. . .

1. Remove your spark plug wires.
2. Remove your spark plugs.
3. Keep your hood open.
4. Get in your car and try to start it up.
5. Your car should turn over, or try to at least. . . you should see water pop out of the head, and if you had enough water taken in, you should see alot of it pop out.
6. KEEP DOING THAT until no more water comes out of the head.
7. Let it sit for about an hour so you make sure its 100% dry in there.
8. Reinstall your spark plugs or replace them with new ones altogether (they're cheap). And get IRIDIUMS.
9. Start your car, this should work.
10. It worked for me good luck and clean your baby afterwords b/c that water spewing out is really nasty rusty stuff. I didnt want that sitting on my Integra much less my Z or any Z for that matter.


GOOD LUCK !!! Hope that works. Let me know what happens.

Denny

If it's not even turning over, then it's not hydro-locked.

Let's define "Hydrolock" just so you're clear about what it is (and if you know, I dont mean to insult your intelligence). Hydrolock is when you injest enough water into a cylinder (or cylinders) to actually prevent the piston from reaching a normal TDC (top dead center). You can't really "compress" water (you can put it under pressure, but you can't reduce its' volume by doing so), so once you get a greater volume of water in the cylinder than there is space to hold with the piston at TDC, you're in trouble. The result in most cases is a bent rod, since something has to give. In your case, I think you're ok. It would take a tremendous amount of water passing through the filter all at one time for this to occur, and I doubt a "splashing" could do it.

What do you mean exactly by "turning over" maybe iam not understanding this term.
And yes i understood what hydrolocking it, i actually had someone explain it to me on the phone today haha. Iam just thinking the worst pretty much so i may not be surprised if it is something bad. Oh and here is the vid of me trying to start it just a few mins ago.

Oh and might i add as i was leaving the car and i locked it. When i hit the lock button the horn seemed realllllllllly weak, like low on battery. Which i tried to jump it today, but to no luck it didnt work.

Could it possibly be the MAF was ruined when water was sucked threw?
