I have an 88 F-150 with the inline 6 engine with EFI. Where is the PCV valve on this engine? I replaced the crankcase ventilator already but I can't find the PCV valve. Thanks for your help.
Reach under the back of the intake manifold and you'll feel it on top of the valve cover. Make sure the engine is cool so you don't get burned by the EGR valve.
