BOV releases every 2 seconds?? it should only release when u let off the accelerator (someone correct me if am wrong)

i am guessing u bought the car used cause i think i remember u asking about replacing the exhaust cause it was 2 loud right?

ACD fluid will go up and down. if u want an accurate measure look at the level before u start the car the next day. (or letting it sit for a while)

 

yes in city driving, it releases only when i let off the gas.... however, if cruising on highway, if im doing a steady 75-80mph, it releases every 2 seconds on its own.

.thanks for the ACD tip. i will check tommorow morning, when car is cold

 

ummm about that bov issue i have no experience with aftermarket bov's so i can't help u there much but i don't find that normal releasing on its own when holding a constant throttle input. i think u have an ssqv bov there judging from the picture u provided. so anyone one with one of these is this normal????

also since u have an 06 ix i am gonna go on a good guess and say that you will find your acd fluid is at a normal level. if u have to add some i stress that u put in the proper fluid cause any damage to the acd won't be cheap.

 

05 Evo 8's come with a 10.5 hotside also. Thats when the 10.5 came out. It may be on the 04's also but im not sure about that.

 

i just read 10.5 came in 2005-2006 only, not '04

 

Yea I wasnt sure. I know my 05 has a 10.5 hotside

 

someone correctly mentioned its a ssq bov, meaning it is not a recirculated (diverter) valve, meaning it is releasing metered air (air already accounted for by the MAF). Look up this topic, especially if you are having drivability issues.

This is also why it is "loud". The air it releases should be diverted back into the air intake track, not to atmosphere.

It is a "normal" valve for a car running a speed density system, but not a Mass Air Flow system, like a stockish Evolution, which is what you have.

I was talking about the fluid level being normal not the BOV.
