Review on Motorcraft EV127A Positive Crankcase Ventilation by Norman Costello

I have a 1987 Mustang LX Convertible. It has a 2.3 liter engine which I really like. I have owned several over the years and they are a very reliable team. I know one thing as a fact. OEM factories and 85% of the aftermarket are Chinese junk these days. This is the case with Purolator PCV valves. I tried the one they specifically recommended and you know what. . . High idle speed of 1000 rpm, which does not decrease even after cleaning the computer. I then bought a new Ford MotorCraft PCV here at Revain using my Prime account (which I give 5 stars straight away) and guess what. . . Quiet idle with no complaints. I did this as a fun test. My pony is OEM and will remain so. Motorcraft Rules and the aftermarket are just looking for money. Kind regards! Don't let the low price fool you. Cheap is cheap for a reason.
