Curious i read a post while ago about the TIAL bov opening up on idle. What were the cures for this. Besides possible spring changes??

you need to change the spring that is what the problem is

ok cool thats whats i thought. We are having issues with the Skyline but ITB's pull a strong vacum ive been reading on this motor

b18bturbo

check your vaccumm and see what it pulls then go to the tialsport.com website and get the right spring usually most if not all honda etc usually pull enoughf or the 11psi

since ive seen a bunch of questions on this lately, ill ask one too...

the engine produces say 20" at idle. we use the 11lb spring so that the valve stays closed at idle. and opens when the throttle is closed. when the throttle closes the engine is gonna produce slightly higher vaccuum than idle correct (say 22" for a split second)?? and thats why the system works the way it does?

geez i sound like a newb asking about the way a BOV functions but obviously the tial is slightly different.
