GReddy Type RS bov leak at idle help - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hellos lads,

I recently installed a GReddy RS bov on my sr20det. At first it didn't open up at all so I did the spring mod (removing the smaller spring) and bam, now it opens up but it leaks considerably at idle. I tried searching but no concrete answers. Some say it's supposed to leak at idle, others say it shouldn't. If I tighten the adjuster, then the leak at idle GOES AWAY, but then I get a half ass blow off and a compression surge. But when I loosen the adjuster, the bov works perfectly, but as mentioned, will leak at idle. I can't seem to find the right point. Any suggestions are greatly appreciated.

Thanks in advance.
