Re: TECH -- Nope, no honking noise. Where can i find out more info. on this oil separator valve? Is it the same thing as a crankcase ventilation valve? Thanks.
1 more piece of info. that might be helpful: If I rev the engine while idling, the noise does NOT show up.
Re: dakbimmer -- Yes, I checked some of the other threads concerning whistling noise. It seems to be a common complaint, but no consensus on the root cause(s). Let me know if you ever find an explanation. Thanks.
