There has been some info out there about replacing your PCV valve with a more restrictive "gt500" unit.
Well My local ford dealer has the Correct PCV "EV-279" listed as a 5.0L Heated PCV. It is noticeably more restrictive when blowing through the EV-279 and the Stock BLUE one.
EV-279
Full Ford P/N - 6W7Z-6A666-AA
Pictured here - (blue = stock, brown = ev-279)
Now it is a heated PCV so a little cutting is needed to fit with the valve cover, covers. I took a small hack saw and took the connector off. After, you get the following -
If this works to help keep some of the oil out of the intake, only time will tell. But as you can see from the stock PCV valve, the parts that are discolored have seen oil. It also looks like that the passanger side PCV valve gets oil slung on it by the cams, there is no baffle on the inside valve cover to protect the PCV valve.
