sucked up water

hey any help appreciated

A few days ago Southern California had a gnarly rain storm and I happened to hit a huge puddle . The car kept driving no noticeable difference drove probably 15 miles after I hit the puddle ...

Well got closer to my destination and tried to get on it a bit only to get a flashing cel and loud misfire.. Limped it into the garage and started ripping the front end apart, water Droplets in my intake, forge dv, and dv pipe.. How ever there was about 32 oz of water in all my intercooler piping and intercooler..

I pulled the plugs and coil packs everything was dry and looked good. So I took off my catch can and rear and front pcv and all sensors that had gotten wet.. Should I take my throttle body off and clean that as well ?

If the cylinders were dry, (you turned it over and evacuated moisture) you are probably ok.
Whew.... that could have been bad.

Yeah i hope everything works alright once I get everything dry. The car never shut off or changed the way it drove only when i tried to boost. Would start up and drive just fine can't believe it didn't lock up

I hydrolocked my focus a few years ago. You'll know if it happens. It's like running into a brick wall. I snapped a rod.

Glad you were able to dodge the bullet.

Hope everything turns out ok. If not this is a covered comp loss with insurance companies.

That's good to know!

@socalhatch- As stated above you would definitely know if it was bad! The CEL was most likely from the dissplacment of water in the IC. Get everything nice and dry and void of water and you should be fine.

That's what I'm hoping for ! Throwing everything back together in the morning so we'll see how it goes !

Let us know how it goes today!
Oh boy I don't think it's good : \....

So I had the whole boost system completely taken apart, rear pcv front pcv and catch can, and all boost piping and intercooler completely off along with intake and forge dv.. Well it was very hard for the car to start today maybe cause my battery is weak but idk..

So it starts up and it sounds like cold / dry valve tick for a few seconds then goes away then I let the car get up to temp and rev it a bit... I'm not sure if my injectors have always sounded this crazy or not but I think I have a slight knock in the engine now ....

Let it idle for about 10 min and decided to take it out and right away in first it just sounds like a knock pretty bad.. But yet not sure if it's my injectors or not .. Did get a flashing cel on the very first start up then nothing no solid light or any thing.. But it was very hard to start the car.

Question is should I try and drive it at least once ? Or take my engine apart or just part out the car lol.... Ugh fuck

If you bent a valve you'd have a vibration rather than a sound (ticking), in my experience. The flashing CEL, though, is likely the knock sensor picking up a ping or detonation.

I'd let it idle for a while, until it warms up to operating temp. Let the gauge get to the middle. This should ensure that all the water has evaporated.

I, personally, would drive it. If you bent a valve you're screwed either way. Just make sure you're prepared to get a tow if you bust something.

Like me, you know when something is wrong with your car. Hydrocking a car it isn't alway like hitting a brick wall. Sometimes you get just enough water in the cylinder to bend a rod without breaking it. If you suspect this may have happened it will be better not to run the motor at all to avoid an even more costly problem if the rod actually breaks. I am not saying you have a bent rod because it is impossible for me to know but your detailed description and amount of water involved certainly makes it a possibility. You probably need to have a look.

Mine drove for about a week, every day, before letting loose. I had a funky vibration in the clutch pedal before it did. But it drove fine. It was like a tick tick tick, each crank rotation, varying with RPM. Like tapping the backside of the pedal with a wooden dowel rod. The initial damage did feel impactful, in my case though. It stopped the engine dead in it's tracks. The engine seized momentarily, due to the water pressure in the cylinder. But it started later on (after pulling the plugs and running the starter with no spark or fuel for a while, and later ran OK for a few days. With a complete stop, at hydrolock, like mine, I'd do a teardown in a heartbeat, to save/reduce the catastrophic damage. But a little water in the intake tract... I'd run it cautiously, and see what it does.

I agree that you will want to check it out. I just can't think of a better way than a teardown. And the cost and time involved is very high.

that's what I'm worried about I'm not sure if its just the normal loud injectors and I'm over paranoid now that i found so much water in the plumbing. If i take everything down I'll do rods and pistons to go with it. I ran the car again after the post and let it idle for even longer, it did seem to settle down on the ticking noise and revved to 3k no problem. Really don't want to boost and get misfire's and dead pedal again or even worse.. Maybe log for knock ?

Yeah nothing was that catastrophic no shut down or vibrations or weird noises until i tried to boost. I ran it again after the post and it seemed to idle a little bit better and revved to 3k nicely. Still afraid to do anything more than that really.

That's the problem with stuff like this, there is no sensor or system in place to tell you how rods and valvetrain are doing. Only thing I can think of would be to perform a compression test. Theoretically, a bent rod won't allow the piston to travel as far and would equate to lower compression in a cylinder with a bent rod. Something to consider and a fairly easy test to perform. Like so many others, I wish you were closer so i could physically help you out with this.

I know what you mean about the paranoia with the injector tick, I go weeks without driving my car (months when winter hits) and I always feel like it's louder ot there's a new noise. Drives me nuts, but thenI say screw it and just drive it. But mine is not my daily.

Yeah sucks that this happened. How ever the car seems to be fine drives fine have t been full Throttle yet but should be ok... Now that I drove a new wrx yesterday I might just sell the car :( no room at the house to keep for a project car and maybe thinking about just getting a new car and leaving it stock for a while.. No head aches lol

So the Car works great no problems at all, seems like i dodged a huge bullet !! the wrx was nice and all but my car is just so much faster, I could never sell it after driving it yesterday plus no monthly payment is very nice . Thanks for the help/advice ! time to continue building it :)

I think sometimes we get oversensitive when things happen but I've gotten to the point where I think I can hear how much oil I have, lol.

If one has comprehensive wouldn't it be better to just see if it fails before taking the engine apart? The deductible could wind up costing less.
