PCV and hose replacement
Hello, this is my first post on this site. Thank you in advance for the help.
My truck is
1996 F150 XLT 2wd 5.8L auto
I have a whistling noise coming from the passenger rear side of the intake where the pcv hose comes from the valve cover (at least I know its coming from that area). Problem is, Im not able to fit my hands or much of my fingers behind there to feel for any possible cracks or leaks. When it gets warmer outside, I will try a mirror, or something else to inspect the area.
My question is, how does one remove the pcv and inspect the hoses/connections for any problems when its so difficult to reach behind there. Do I really need to remove the intake first?? Are there any photos available in the forum that you know which would give me a good idea of what the connections look like and how to remove? Until I get a better look at the rear part of the intake, I am leaning toward the problem being in a connector or grommet seal.
After the truck is warm or the outside temperature is warmer, the sound is not as noticeable at all. But while cold, it will whistle and raise in pitch/tone during acceleration. Im not expecting a failed intake gasket, but that has not been determined yet.
Has anyone experienced this problem and repaired it themselves? Im not eager to let a dealer explore my wallet that much. Any relevant advise or opinions are appreciated. Thanks

It's just a tight fit. If you can't get your hand in there then get some pliers or something and be gentle. No, you don't need to remove the plenum. I think it's more common for the elbow connection to be cracked than the grommet the PCV sits in. Also, if it's an aftermarket PCV, there may be two places to connect the vacuum line to the plenum. One should be plugged (the smaller one) and the other should have a line to the plenum. It could be the smaller port doesn't have it's plug in it any longer which is causing the whistling.

That's a great point, thanks again. Something I will look at when the weather is better
