If it was a busted coolant hose you would have coolant dripping onto the ground eventually and a warning buzzer going off for a low level. It is probably a blown coupling on the turbo outlet or a gasket leaking. Take it to a Rotary specialist since it appears your mechanical diagnosis is weak is my best advice.

thank you badddrx7 but what about the air blowing out of that pipe?

If you have pinpointed the "pipe" that is blowing boost, then take a pic of it and share with the rest of us. We'll tell you what it is and how to fix it right - how about that....

You could have a pinhole leak shooting coolant onto the hot part of the manifold. In that case you won't see dripping. You actually would have a risk of fire or of the hose bursting and doing engine damage. Definitely go in and find the source, and have new turbo coolant hoses ready to go.

if your having trouble with coolent hoses, you might want to get a shop to swap out all of them with new ones. when one goes the rest usually like to follow

If this has been going on for any length of time at all the man should see a drip appear under the car or a warning buzzer - if it works. Small seeps don't produce white smoke, normally they burn away and leave the tailtale stain. All it takes is a 20oz lose of coolant before the probe is uncovered and then Buzzzzz..

Have you been adding coolant ?

Thank you for the info guys. I Drove it for about 14 miles to day and everything is good except the boost. There Isnt any white smoke and I have aready replace the hoses a month and a half ago, but it started right after i change the coolant hoses. Here is a pic of the pipe that is making a weird sound blowing out air from the engine.

BTW the circle holes are the same just the 2nd and 3rd pic is with the hose off the pipe leading to the engine.

thats the bov comming from the primary turbo. it should be blowing air right off start, thats common.

No, it's not... there's only one BOV and that's not it.

The air blowing from that hose is boost pressure from the secondary turbo being released via the charge relief valve.

If you rev up the engine - the valve should close.

If the car is just idling and air is coming out - its doing exactly what its supposed to.

Looks like the vent for the Airpump/EGR system to me, it is normal for it to blow air. If it makes a moo-ing sound buy a small filter for it and it will kill the sound. By the way, his CRV and BOV are routed to his intake tubes in the picture.

Be carefull about what advice you give people,, that pipe has nothing to do with the airbypass or the blow off valve. Like chadwick said thats the air releif pipe from the air control valve for the air pump (it basically vents air that isnt needed from the airpump back to the airbox),, and also like chadwick says if its giving an unwanted noise them a small airfilter can be attached to quiet it down a bit.

zerox678

but i've never had that mooing sound before, and now i have it she's not boosting over 6 psi. wat gives?

Your problem has nothing to do with that pipe,, start here........

Now once you understand how all of these trap doors, solenoids, blowoffs, vac hoses etc works Zer0X, it will then be time to go single Turbo

LOL But I still love the low end torque from the twins.

To be honest when you first start studying the twin turbo set up it lookes complicated,,, but read and study and understand how it all works then when theres a problem i find it not that hard to fix.
