Okay, I'll be beating a dying horse with this post.  I got old style valve covers years ago at a swap meet.  They're beautiful, but they have holes for a breather and oil fill.  I am swapping in an EFI 351W in place of the 5.0L in my Crown Vic.  If I install one of those Trick Flow oil-fill necks and I plug the breather on the other hole, will that avoid an unmetered air source?  I plan to keep the pcv system.

As long as you ensure a breather hose past the MAF sensor, no problem. IOW..... you need the PCV valve + a breather hose sourcing its air after it has been metered by the MAF.

Wow!  That was fast.  Yes, I was going to figure out how to plumb a hose from the oil-fill fitting to the pvc piping that I am using for a CAI.  I was also wondering if I could connect a hose from the oil-fill to the nipple on the throttle body like the stock speed density set up on my car.  However, it would be much smaller than the stock set up on my Ranger.  I don't know if that would make a difference or not.

Stock Crown Vic 5.0L.  Copper tube running from the oil-fill tube to the throttle body.


Stock Ranger 4.0L.  Rubber hose running from the oil-fill tube to the zip tube behind the throttle body.


Does the size and location after the throttle body matter?

Breather hose in the 3/8" ID range or bigger = OK. Smaller might be acceptable but it will hinder crankcase fumes flow and may increase crankcase presure under extended WOT runs if the PCV side cannot handle it.

Okay, makes sense.  I should remove or plug the elbow on the throttle body and figure out a way to plumb a line from the valve cover to the air intake.  Shouldn't be too much of a problem.

Funny how big that hose is on the 4.0L compared to the much smaller hose on the 5.0L.  And yet both engines don't see any action passed 3k rpm.  LOL

Thanks Joel Smiley
