I was hanging out with Rondog and lou from the CL-S board like 2 weeks ago. We were driving on a highway when Rondog decided to accelerate. All of a sudden his engine starts bouncing off the rev limiter. I see him roll onto the emergency lane and i follow. The car wont stop revving so we shut her down. He actually had to put it in neutral to roll off the highway. We pop the hood and to our suprise, the intake tube came apart where the bypass valve connects. So we reconnect the tube and it wont sit tight. I told him that something had to be stuck in there. The gas pedal had a lot of play, and the throttle cable was tight. So we took the intake off the throttle body and sure enough, the rubber ring inside the bypass was sucked into the throttle body. That thing was so deep we had to go get needle nose pliars from his house in lou's car. When we got it out, like an idiot he put the bypass back on. The car was fine after that though, but imagine if that thing would have made it all the way into the intake manifold? What an experience, thats why i dont mess with the bypass vlave anymore. This is the 4th person i know to have an aem bypass valve break apart and go in the motor. Rondog survived, but the other 2 motors had some damage.

There was a recall on the bypass valves, not sure if Rondog qualifies for it.

for just that reason. better performance noticed too!

Never heard of this problem. Hmm... I had my bypass in there for more than 1 1/2 years... no problem so far.

I never put one in because i was scared that the foam would degrade over time......just take it out and PAY ATTENTION when driving not to hit any huge puddles and everyone should be ok

samkws

is there any gd for putting a by-pass valve?

isn't it only gd for turbo cars?

bug230

wow that was a close 1.

njtls

hmm..would i bypass help in the snow...or do i not need one all togehter?

oh that one made my day

TOOL!!

lol we are talking about the bypass valve for cold air intakes. In case water goes up the intake, the bypass valve will open and suck in air from higher up instead of sucking the water up.. Turbos use blow-ff valves =)

samkws

oooooooopsssss......

my bad...sorrie...

i am not that gd in eng...got messed up...:p

Aki's TL

wow, that is scary! Yah, good thing that thing did not get sucked up into the manifold!
I have one on now. I think I'll put on a cautionary piece of wire mesh at the top part of the CAI tube inside/under where the top of the bypass valve connects. That way, if that plastic band breaks off it will hit the mess.

if i were you i would just leave it before something else gets screwed up. you will mess with the airlflow too.

many (most?) factory turbocharged engines use a bypass valve, not a blowoff valve. just like my mr2

i was a little confused when i read the topic as well. i thought he had a turbo CL at first...

tuRb0mikEy

they do the same job. it's the same thing

>> they do the same job. it's the same thing.

Not even close.

A blowoff valve goes between the turbo and the intake manifold, and is used to release pressure when you let off the gas, since the turbo will have already compressed the air at the higher throttle setting, and you don't want to force that much air in and cause your engine to run massively lean, which would burn your rings, etc.

A bypass valve goes between the intake and the manifold (or the turbo/sc if you have one), and is used to prevent water from being sucked into the engine. A stock intake is long and twisty enough to prevent this on it's own, and a short ram is presumably high enough up to avoid the issue altogether.

I almost chose not to get one for my TL, given that I live in LA, where we see rain at most a few days in a year, and I figured I can avoid puddles. If I had done that, I wouldn't have a car anymore. The last time it rained I ended up in a 7 inch deep puddle with no chance to stop or swerve, and no way to avoid it even if I'd seen it ahead of time. I actually felt the car kick and heard the intake sound change to a horrible sucking noise, and my filter was dripping wet when I checked.

As far as the "fall-apart" issue, the recall was some time ago. I bought my intake almost two years ago now, and got the updated version of the bypass valve.
