Mgrene Posted August 8, 2017 Share Posted August 8, 2017 As subject state. Any of you seen this alternative solution before. There is nothing attatched to it which to me looks strange now that there is an o-ring at the end. Quote Link to comment Share on other sites More sharing options...
Mgrene Posted August 8, 2017 Author Share Posted August 8, 2017 Found out it is looking like that because the plastic has been broken of. I assume it is not correct to drive with the valve like that so my question is now if it will hurt anything if I just block of with a bolt?

Mike2JZ Posted August 8, 2017 Share Posted August 8, 2017 If I'm not mistaken then that valve will allow air separate to intake air to be pushed into the inlet manifold, so when you steer on idle the revs do not drop too far and stall the engine. I think previously I had the valve not connected at all and didn't really notice a difference. If you have a standalone then you could get around this by getting the standalone to allow more air through IACV when it detects PS is being activated.

Chris Wilson Posted August 9, 2017 Share Posted August 9, 2017 As hydraulic pressure rises above the diaphragm spring pressure in the valve, (as the PAS is loaded up), the ports open and bypass atmospheric air around the throttle plate to add idle RPM to balance the load on the engine. As you say, you probably won't notice much difference, except perhaps on an engine with wild cams that produces sod all torque at idle. Looks like someone has blocked off the port with "something to hand". Quote Link to comment Share on other sites More sharing options...
