Those that are running CAI. What are some remeadies for all this rain and flooded streets?

Other that stock intake.

Drive safely in the storm.

 

Don't drive through 2' deep puddles?

 

Never had a problem with mine.

 

look, seriously, the depth of the puddles it would take to hydro lock an engine with a CAI are puddles you wouldn't drive your car through in the first place.

 

And if you do drive through a puddle so deep, you almost deserve to get it hydrolocked.

 

get a short ram?
all i can think of is a BPV and a hydroshield to help you protect it.. other than that the filter is pretty well guarded by the splash guard and fender lining..
and what they said ^

 

QFT

 

Yup, those are pretty much your options. Keep in mind though that the bypass valve doesn't open unless the pipe is actually submerged, otherwise the intake will suck in splashed water like a shop vac, and on our xB it takes about 2 tablespoons to lock a cylinder. The filter will also stay wet after being splashed, though I'm not sure it would be enough to hydrolock.

I ran into this a few years ago and it cost me an engine and $500 for a replacement used block. I had the TRD cold air intake, but Toyota does NOT warranty it for the 2006 xB. It was not raining the day the engine got ate, but did the day before. The technician claimed that water got past the filter and sat in the intake pipe; on the TRD design the filter is above the pipe and they claimed it acted as a water trap like a plumbing drain.

I can't say if this was true or not but didn't have another explanation, the rod was snapped but the piston faces were clean, no detonation and the rod bearings still moved so no oil lock.

After that I switched to a short ram and got an Injen hydroshield. I figured that then at least if water splashed up it would roll off the hydroshield instead of getting absorbed by the filter and possibly sucked in the engine.

 

stay away from flooded areas I have had mu CAI in my tC for about 2 years & never had any probs when it rains you can also buy this AEM Bypass Valve

 

just make sure you have the fender lining or get a short ram lol i got water in my fujita cai about 2 months ago and bent a rod so my engines messed up im just waiting for it to completely break lol =) i didnt have the fender lining and my tire kicked up water and got in the intake

 

i always wondered what that spongy looking thing was on the TRD intakes.. now i know, thanks!

 

QFT.. that bypass is pretty useless really unless your car is already swimming..

which then you can refer to..

 

I know I'm from Wisconsin......

But, I had my share of driving through flooded areas with a CAI.

Yeah...I driven through a flooded residential street that water was waving up to my windshield. Let's just say, car still drove through it & didn't get hydrolocked. In fact, if I can remember correctly; I think I driven through four other flooded roads/streets that same day but that was the deepest.

Most cases, its hard to avoid those streets. Two of those streets were two lane country road that you couldn't reverse on. Another moment, you're stuck in Milwaukee for a Scion show. The dealer happens to be on low ground while the connected streets are inclines. So, you're stuck driving through it. I heard least five other Scion owners hydrolocked their engines because of that show.

 

Thanks for the responses, well the useful ones anyway!

Not sure the AEM bypass will work on the AEM CAI that i'm running.

Drove in circles trying too avoid flooded streets, gushing manhole covers, and SUV drivers.
No problems.

the bypass filter can be altered to always be open ......

 

The AEM bypass will work you need to call AEM to get the right one for your CAI ;) & I love mine w00t

 

It can, I am very interested! Could save me some .

 

BAD idea. It would also be drawing air in after the MAF sensor, and unmetered air will not make the engine run well. It'd be pretty much the same thing as leaving the PCV breather hose unhooked from the intake.

 

^ I'm pretty sure the BPV is before the MAF so it should be OK. Check the pic above.

 

yeah every aem one with the crappy bypass on it has the bypass BEFORE the maf . but hey maybe in bizzarro world......
