302 PCV Valve

OK. What is the deal with replacing the PCV valve on a 1990 F150 EFI 302 motor? I got the old one out no problem (as it pretty much fell out), but I cannot get the new one in. The grommet alone will go in, but there is no leverage to put the valve in. Do I put them together first and somehow put them in? Or do I have to remove the entire intake manifold assembly to get clear access to the valve cover? What is the trick here?

302 PCV Valve

Hey,

I have an 89 302 EFI that I have replaced the PCV valve on just recently. It will go in, but takes some persuasion. What I did was connect the line to it first and then put it into the valve cover. It took some work, but it went in

I did mine just recently, too, but I didn't have a problem. Is it possible that the wrong grommet was in the box?

Hook up the pcv to the tube that goes into the intake.Put a little oil on the bottom of the pcv valve.The grommet should alredy be in the valve cover.Start the pcv in at an angle and push it in.It takes a little wiggling but it should go in.

I had the same issue installing mine. I bought 2 different sized grommets, not knowing which would work, tried to dry fit them & one was too lose, the other too tight. Stupid me decided to ream it out a bit to fit. That worked great before installing it, but after install it leaked oil like crazy. Through trial & error I found out you can throw it in a pot of boiling water to soften the grommet then press in the PCV valve, or install it & run the motor for a bit to heat up the grommet(if you don’t mind hot oil blowing out), then press in the valve. No hydraulic press needed 😂
