jwmcgregor Posted January 22, 2019 Share Posted January 22, 2019 Anyone know if i can delete this component? I suspect the crankcase pressure is somewhat regulated by the resistance required to spin the diffuser. Can I hose the valve cover vent to atmosphere and put a plate over the hole in the block where the diffuser mounts? Thanks! Quote Link to comment Share on other sites More sharing options...
fjh Posted January 22, 2019 Share Posted January 22, 2019 I am not Sure ! However ! Be aware that crank case pressure is monitored by the ecm I wouldn't be surprised if it throws a code for it if it is removed! Just Sayin! Also Its one of the better Ideas of the engine design ! Don't know why you want to delete it ,there is so much other stuff I personally would gladly see gone ! 😡 Quote Link to comment Share on other sites More sharing options...
jwmcgregor Posted January 22, 2019 Author Share Posted January 22, 2019 Leaking and it's expensive. Mack parts guy didn't find a gasket kit for it and new one is stupid costly. Looks like oil engine oil turns the turbine. Quote Link to comment Share on other sites More sharing options...
fjh Posted January 22, 2019 Share Posted January 22, 2019 yup make sure the bolts and screws are tight we see them come loose lots Quote Link to comment Share on other sites More sharing options...
Mackpro Posted January 22, 2019 Share Posted January 22, 2019 As Fjh said,it’s tied ties to the crank case pressure sensor and I know it will set a fault code if the inlet pipe is not hooked to the CCV filter on a 13 year model and up. On the older trucks I don’t know. The part number for the O-ring kit is 21475236. This is for the MP8 and does not include the mounting o-ring.

Rockwell Posted January 22, 2019 Share Posted January 22, 2019 (edited) I was able to get a gasker kit no problem for mine thru H&H Mack, Rockaway, NJ. Maybe you can order it from them and have it shipped. My gasket turned brittle cause a leak. Simple, easy fix.
