PCV Valve (When Too Replace)

[AzFireGuy79]

Another vote for the Motorcraft OEM pcv. I only use Genuine Toyota in my tacoma and Camry. They are the all metal type. I do mine about every 60K. In some cars aftermarket pcv's are ok but I have noticed this is not the case in fords and Toyotas thus far. If I go aftermaket in someone elses car, I usually go for Purolator. They seem to be decent.

I usually use Purolator or whatever CarQuest has for my small block chevy.

But, on the Marauder, I am going to stock up on a bunch of the Motorcraft PCV Valves, I can get them for half price online as compared to going to the dealer.

I even called NAPA and they only have there brand and the cost is the same as if I went to the dealer.
