6.2L Ticking and IMRC
All, I recently purchased a 2019 F250 6.2L with approximately 85k miles. The ticking noise appears to be related to the IMRC issue since when I unplug the electrical connector to the solenoid, the ticking noise stops. After reading through some of the posts on this forum regarding this issue, I have more questions.
Apparently, a new intake manifold is the recommended fix, so did Ford make the necessary changes to the manifold assembly/design to prevent this issue from occurring again with a new manifold? I had read that new manifolds were on back order. Are they now available?
I also read that the runner plates/doors could break off and move into the engine causing significant damage. However, I haven't read about any instances of this actually happening. Although I find the ticking noise annoying, I can live with it rather than spending a lot of money replacing the manifold, if it's not necessary.
Thoughts and/or suggestions?
Thanks!

That is crazy - how can a newer engine not have repair parts?
It seems there is no federal law that requires spare parts be available except during the warranty period (Consumer products are not required to have warranties, but if one is given, it must comply with the Magnuson–Moss Warranty Act ).
So until FORD decides to force the issue for whomever is making the replacement parts, looks like we are SOL on new replacements for now.
Seems ripe for aftermarket money to take this product to maturity and run with all the profits!
https://www.law.cornell.edu/cfr/text/49/541.6
There is one caveat to this though. If the vehicle was ever sold in another country, and that country has a repair parts requirement, then the parts will most likely be there.
The Raptor was sold in other countries, and if 6.2L, the parts may be available from there. From Wikipedia, "The SVT Raptor is sold in the United States, Canada, Mexico, the Middle East (including Afghanistan), China, Ecuador, Chile, and Peru."
So maybe available from one of these countries, but otherwise, still SOL.

So did some more reading on this forum and found this post. Current posts are near the end. I concluded that 1) even if one can get a new manifold from Ford, it may still develop the same issue. That is, Ford may not have made the necessary modifications to prevent the flaps from failing again in the future, 2) there haven't been any reports of the flaps actually falling apart and damaging the motor, and 3) many users are disconnecting the solenoid and driving as it. However, without doing a tune, a CEL will stay on. Long-term consequences of driving it without a tune are unknown.
It's unfortunate that Ford isn't doing a recall on this issue since it's so prevalent. I recently bought this truck and really like it. If I hadn't just put a camper on it, I'd probably sell it.

5 star
I told my service advisor that ford should just come out with a software update eliminating the imrc so we don't have to go to 5 star tuning to get our own. After all that imrc does do much except for maybe a little less emissions. He told me to stop making sense.

After reading about the intakes being on backorder, I've done some searching online and they seem to be available from at least this one Ford dealer, unless I'm mis reading.

Probably not. it depends on the purpose of the IMRC - is it performance/gas mileage or is it emissions?
Either way, if the engine was certified with the IMRC, it has to be re-certified without the IMRC by FORD. And that costs more money for the re-testing.
IIRC, it's an emissions/gas mileage thing.
https://www.epa.gov/ve-certification...ars-and-trucks
as an example, FORD has received credits for these vehicles as listed below:
https://www.epa.gov/sites/default/fi...2017-02-06.pdf
If FORD changes anything on those, the credits must be reevaluated and possibly returned - costing more money over just a re-design cost. I would bet that nothing is going to change just because of this alone.

That's good info, although disappointing. As you suggested, it seems unlikely that Ford will make any changes to the manifold, so not much benefit in going through the expense and effort to replace one.

Im not enthused about the imrc in my 6.2L but its for sale so I wont have to deal with it breaking and Ford not supporting it anymore. Which it seems they are already doing with no revised intake and the discontinuation of the original intake.
