has anyone had issues when reinstalling pcv valve that it will click down, turn a click in the direction it needs to go but won’t rotate the rest of the way like at 4:16? dont want to break anything and i can feel the valve flexing when i try to put too much pressure
You dont just clean out the old valve with some solvent?
Were does the other end of that hose go??????
Great video, blessings.
Thank you for this video. I found this same problem yesterday on my 03 liberty and now I know what happened[
Do you think these engines would benefit from an OCC or would it be detrimental?
Great video! Thank you so much!!
Thank you man, this video helped me a lot.
Hey Martin, I have an 04 second owner with 92224 miles don’t know if it was ever changed, should I just do it? Your videos are my go to.
Happy Holidays
what codes were you chasing
Thank you so much. I had the exact same issue
Hey MartinBuilt
Can you make a video for replacing the: crankcase breather hose assembly on a 02 Jeep Grand Cherokee Laredo 4.7L V8
Part number: 94364GB
I can't see what kind if connectors the hose elbows connect to back there. The middle one connects to the resonator air box on the driver side and two connect in the back down behind the hood.
My WJ is 21 years old and I've broke several plastic tubes and connectors related to the PCV valve and breather tube due to it being very hard and brittle. I'm afraid to yank it off and find the connectors are plastic that break on removal even with Blaster silicone spray
Appreciate you for the video
You're so helpful! Finally, I found a video relevant to my problem.
I looked everywhere for that thing and couldn't find it
Hey Martin. Some times I hear strange noise from PCV valve on my Jeep WK 4.7 – vibration and scratch. I had replace pcv valve, but issue is same. May be it is normal?
While I chase a Mistry rough idle with no error codes on my 2000 GC Martin's videos help me to not only locate the parts but also getting them changed with some extra tips along the way. As a owner of a 4.7 I will be following your content. Thank you.
How do you replace the elbow on the back of the manifold? Don't care about the pvc valve
Great video.Have you ever thought of doing a catch can on the 4.7 l v8.I used them on 5.7l hemis and they catch alot of blow by.
Perfect, thank you
Do you know where the oil gallery gasket is located?
Always quality content from Martin.
I was actually searching for your video about the PCV upgrade and found this video. My 4.7L WJ is leaking oil onto the Y-pipe and I need to get it fixed. I thought is was the valve covers, but I'm starting to think I have an oil leak in the PCV system. I replaced both valve cover gaskets a while back (very carefully) but they still leaked. At least I thought it was the valve covers…
Your awesome brother
