Yup, it's the oddest thing.

Re: MEFI-4 Idle Hunt at Start Mystery
Maybe wrong here, but IF the ECU was designed to work with a PCV valve in the covers of each engine then they should be there. See if there is evidence of the PCV valves being removed for some reason.

Re: MEFI-4 Idle Hunt at Start Mystery
is it like that on both covers on the same engine?Delorean6855 wrote:Source of the post Finally getting back to this... so this is where the PCV valve should be...I remove the hose and it's just a hose barb. Super weird... the 6.0 schematic says the engine should have one. ....
BTW, take a closer look at that fitting that looks like a hose barb. Some PCV valves look exactly like that at one end and are threaded in at the other and look like a simple fitting.

Re: MEFI-4 Idle Hunt at Start Mystery
The other valve cover hose goes to the flame arrestor, correct ?
