Fuchs915 Posted November 26, 2019 Share Posted November 26, 2019 My ACV is making buzzing noises, which I understand means it's toast. It's the little plastic valve that is connected to and sits next to the oil tank, mounted to the body. I am not sure exactly what it does, but the valve apparently opens when the car warms up, when it stops buzzing. Also stops buzzing if you blip the throttle. Question is can it be deleted without ill effects? The replacement part is different, so needs a different mount and has different diameter connectors which means I will need some modifications for the connected pipes to fit as well.

SP72 Posted November 26, 2019 Share Posted November 26, 2019 Can’t help with the delete info as mine was removed as part of the ITB install. I have a NOS item if you need one though. Does yours look like this?: Link to comment Share on other sites More sharing options...

MIne is the original (I assume) all plastic version, which means some modding is needed for the replacement version you have. But I can then tell people I have a modded 911, so all good. Let me know how much you want for the part. Thanks also for the links, helpful with explaining what it does and the modding process too. Link to comment Share on other sites More sharing options...
Phill Posted November 27, 2019 Share Posted November 27, 2019 Having read those links it looks like something that can be deleted altogether. Link to comment Share on other sites More sharing options...

Not so sure, I thought it helps stabilises tick over, on a cold engine. Edited November 27, 2019 by SilverWT Link to comment Share on other sites More sharing options...
