2018 5.0 Issues
#502
My dealer has 2 new 5.0’s torn down in his shop. He says there’s a problem at the factory and they’re trying to figure it out. This was 2 weeks ago. Just FYI...FWIW.

That isn't normal. I would be getting Ford to buy it back. There is an issue there. After the leaf spring clunking, the warped dash, glove box shelve issue. I would be done with the truck if mine sounded like that.
She gone.

Here is another knocking issue they are going to try and fix with cam phasers and timing chain .....we'll see what happens on April 15th when they install the parts. This is the 4th time in to try and fix the truck. At least they are changing parts this time.

I believe it's an oiling problem.

I believe it's an oiling problem.
So it's been three days since they installed the parts and so far the noise is gone..... let's hope it stays that way. I've attached the parts list above for your info.... I'll let you know if the noise comes back.

I have seen many 5.0's with this issue and I finally found the cause!! BUT a new intake manifold did not fix it. Have a clunk on accel and decel especially under higher torque load? Try this
I have been chasing a clunk on my truck for months and finally figured it out. For anyone with a clunk.. give this a shot and let me know. This is on my 2018 5.0
Watch this at 11 seconds. You will hear it.. now imagine it under full vac..

I unplugged this and test drove.. Clunk GONE. Check engine light comes on but clunk gone. I plugged it back in off course. Dash light turned off in drive or two.. clunk returned of course.

That just disables the IMRC, which are the flaps that make a racket.

I'm aware. I'm also aware that this noise was generated by Ford updating the module from other TSB's. No clunk... reflash for TSB.. clunk. Verified it on a different truck the other day. Went in with no clunk. PCM updated.. Now it clunks.

I said "Wait a minute. I buy a nice quiet truck. It starts to rattle. You guys flash it to fix it. Now it still rattles AND clunks.. you tell me all this is normal and come pick it up??"
Persuing lemon law now.
My first Ford. If I have to keep it.. I will redesign the intake vac control to have a cushion OR I will get a non clunking truck, copy the module, and put the program on my truck.
