RyanG Posted January 23, 2017 Share Posted January 23, 2017 On the late build hpop, the port just above the shaft is the ipr oil dump port correct? Is it normal to have air coming from that port during an air test? I have an 07 in for an stc fitting and never paid attention. I always thought the air coming from the shaft lip seal was the normal leak heard in the crankcase. Quote Link to comment Share on other sites More sharing options...

Matt Saunoras Posted January 24, 2017 Share Posted January 24, 2017 The IPR dump port is the normal leak. Even when you put a full 12v to the IPR you may still have a small leak there, not always enough to hear but if you put your finger over the hole you can feel it Quote Link to comment Share on other sites More sharing options...
