Ok, since most here think a Scion, any model, can be hydrolocked when running a CAI, or SRI, let's hear who has.

If you have hydrolocked your engine on your Scion, please list model, which intake, and the conditions that has caused it.

I have not, and ran w/o my inner fenders, during the rainy season, just to see if it would happen, and it didn't.

I have an xB w/ an F5 Fujita SRI. When I did my own independent test, it was equipped w/ an INJEN SRI.

 

I also forgot to mention that my filter is in the air/water flow from the middle grille on my xB. So water does have a direct path to my intake filter.

Here are the pics:





The filter can clearly be seen in this pic:

 

I hydrolocked mine without a CAI. Well, I think it was hydrolocked. I never tried to crank it after the 8 feet of water receded.

 

Ok, I guess I need t be more specific, you have to be driving the car.

 

i never have and never will!!!

i might of at work with the work trucks but i was power washing/steam cleaning some of the engine bays with the motor running, got enough of the of the water mist into the carb it stalled

 

My car stalled once when it was raining hard in S.F. and wouldn't idle, I have a Injen SRI. Once the filter dried it ran fine.

 

People are still buggin out about that????

 

Hmm, I've driven home to the central valley from Oakland in downpours and never had that happen. Plus I have a double vented hood too!

nope. i did have it sputter in an ice storm (filter iced over on the way back to college).

ive also had to dissemble the whole intake system due to the last snow storm as it got the filer wet and inside the piping wet. i chose not to try to start and let it dry.

works good now and i have the box back

 

hydrolocking is so rare, its more of a myth.

Its near impossible to hydrolock while driving, because if conditions are well enough to actually drive, there is no way water will be deep enough to cause harm.

I know, I know, but I'm just trying to show others who keep telling me that there will be hydrolock using certain intakes. They don't seem to undestand that the car will be at least half under water for it to happen.

 

Yeah, i was more or less posting for those who don't to read, not you. Or anyone else in the thread since the only ones posting actually know better. No matter how many times people like us repeat information, any information at all, another new owner comes along with the same questions. Because they are new, they don't search, because they don't search they post a new thread, and eventually gets locked, its a never ending, ruthless process. But, if theres any light in this at all, you can make a game out of it. "Estimate how long it will take to see when ____ thread gets locked." jk

maybe we should have them make a sticky on top of the N/A sections about how much water you would really hafta take in to lock the motor up, and they shouldn't worry about a lil puddle or some rain with an intake unless you are running open wheel wells, and drive through a 4 foot puddle and decide to stop and eat lunch in the puddle while the car is running lol lol lol. Holy run on sentance.

 

I hear stopping in 4ft puddles, and eating breakfast with open wheel wells also has the same effect. Tests on dinner related meals have not been tested as of yet. I'll keep everyone posted.

gosh you cannot "hydrolock" an engine unless it inhales from submersion, like running into a deeply flooded road.

If the water were only fed in like from heavy splashes, the effect would be to sputter and kill the ignition process.

The effect of plentiful of water splashing in the engine intake but no so much as to affect the seeming-power of the engine is probably not harmful, for water vaporizes and passes out the exhaut. But to shut down the engine very just after it has sucked a lot of water, say from splashing into an OPEN intake is not good for the internals: rust would stain the bores and rings if left shut off for days on end.

If a filter is on the intake, all that the engine is going to get in a rainstorm is a mist and controlled aspiration of water.

In some ways, the engine might even run better and sweeter for the extra water.

For as long as cars have been run on the roads, motorists have noted how the engines run sweeter when the air is saturated with moisture. There's a reason for this, but not germane here.

I have stock intake and don't intend to change it because- I don't want to hydrolock the engine if ever i -must- plow through a flooded dip in the roads here, say, after a tropical storm or hurricane some other rain event.

 

I don't know if it is "most here", since the subject has been discussed ad naseum and the outcome is always that you can't do it unless you submerge the intake (duh) or water somehow accumulates in the intake and gets inhaled all in one slug.

Back in the days, pouring water through a running engine was a shadetree mechanic's way of decarbonizing the pistons and heads. I've personally poured a gallon of water through a 1600cc Datsun engine in less than a minute with no ill effects.

I initiated this thread because there are some who believe this will actually happen. There are plenty of us who know otherwise, and I just wanted to show what conditions are actually needed for it to occur. And they are not conditions that the overwhelming majority will see.
