I suspect this is my issue. I pulled the plug on a trip to be safe. I have been hoping to find a video with some footage of the actual noise. I have made some of mine and will likely post a video to help fill the void out there. I would describe the sound Im hearing from the drivers side reminds me of a popcorn popper. Does not change with acceleration/Increased RPM. Seems to run fine other wise. Just concerningly noisy. And when I put my hand on the cover I believe I can feel something bouncing around in there. If I can get the camera in there and demonstrate the view through the hole of a missing or dislodged baffle I will prior to removing the cover. Otherwise I will show both side by side. Assuming that ends up being the problem. But I am optimistic. Good job with your explanation.

Where did you get your valve cover at?

Interesting. Thank you.

I had a constant tap tap tap suddenly coming from the V-10 on our motorhome engine after a rough road transit. Would not increase in sound, but remained constant. No codes or diminished engine operations. After running toward home from California I stopped overnight in Arizona. Next morning I started the engine and it sounded like the engine was going to fall apart with loud clanging noises. I thought the engine was shot. Then suddenly about 20 seconds later it cleared up totally and the engine ran perfectly and quitely 2000 miles all the way home with no noises at all! I think I have this exact problem and will attempt to remove the cover myself and verify this is the same problem, which so far I am convinced it is. A Ford truck dealer wanted $8000 as he said he'd have to remove the heads just to assess the problem. Many thanks for the video! I hope this is exactly my problem!

Thanks for the super useful video, that had to be so hard to find - This morning it i got a ticking sound also not tied to RPM. Happens when at constant speed or accelerating but it stops immediately if i let go of the gas. Is this similar to your experience - what year is your ford, ours is a 2016, wondering what year ford improved the cover. Thanks a bunch

Thank you, I just got the valve cover off my E450 and have the same problem. Where did you buy the new valve cover?

Quick question when it was knocking while driving would the knock go away while under load? Mine is doing the same one mechanic said it was a spun bearing but I feel like it’s in the valve train

Wow!! I haven’t removed the valve cover yet, but did everything you said up to that point. Sound definitely coming from under the valve cover. Other side completely quite. Thank you thank you thank you

So awesome, I have exact same issue and thought it might’ve been a plastic piece or a nut from a rodent that made a nest on the engine. Stoked it’s not a cam roller or something more technical and intrusive.

Thanks for the video!

Excellent brother!! Glad to know it may be as easy as that. Thanks

Did you also need to pull intake off to get cover off

👍🏿

Please post the part number for the valve cover, it is now listed as "discontinued"

Do you have a part number?

Love it, thank you!!!

My Hero!!! I have the exact same problem!!! God bless!!! 🙏

Thanks

What year is the motor?

Thank goodness for your inspection I think this is the problem with my f350 I pray it is

Thanks for this info. That baffle is actually part of the PCV system. No more PVC valve in these engines.

Hopefully this helps you out!
