Cam Phaser/Engine Failure Reports

[FordTechOne]

That’s interesting data. My recollection is that for those who have posted of phaser failures and subsequent replacements, the overwhelming majority seem to include cam replacements. If it’s just the phasers failing to park correctly, I’m struggling to think of a way that park failure could implicate the cams.

I know we need to give it some time in the field but it does seem to me that the replacements, and more importantly the repeat replacements have calmed down.

Sounds like they misquoted the repairs that were actually performed, or people are confused because the part catalogs list one of the phaser part numbers as “cam” in the description.

No camshafts require replacement for a phaser locking pin issue and no service procedure, Workshop Manual or Service Messsage directs the dealer to replace camshafts for a phaser concern.

So if the start up noise does not bother the customer, it is literally not harming the engine in any way. I don’t have it, so can’t say, and certainly not in anyway a comment on those that chose to have it fixed, but I’d be reluctant to have the motor cracked open.

I had a 2017 RS with the head gasket recall, so no choice. They ended up doing a good job, but I held my breath for the days it was in for repair, and for the first 1k miles or so when I got it back. (Lots of little parts, and screws to inadvertently make a mistake with in that job.)

That would be correct. Cam phaser replacement is not nearly as involved as the head gasket replacement you mention on your RS. If I had an affected engine, I wouldn’t hesitate to have it corrected.

Just got my 17’ back two days ago which had the 4 cam phasers replaced. Went in for P0012 - intake camshaft overly retarded bank 1 and rattle on cold start.

Found the plastic lock pin that fails in the vct unit broke off and lodged itself In the phaser not allowing the cam to advance timing properly.

So while SSM 48455 states it will not affect performance or longevity, there are certain circumstances where it can cause an issue.

Now that is great info, and even if it only happens rarely, would be a great reason to get it fixed.

I kept reading over and over, no affect on performance or drivability, but those things are in there for a reason, I just couldn’t wrap my head around the only negative was noise.

I’m sure mine was an anomaly and that the majority of people will never have the same issue but all in the same thought it was worth sharing

Anything that sounds like chain slap and as bad as it does sound it will shorten engine life,hole in timing chain cover loose chain skip a tooth on a sprocket bad chain guilds etc. IMO

Well your opinion is wrong in this case. But hey. Keep trolling and creating new accounts.

Ok Karen.
3 posts. All trolls.

You’re a internet treasure.

You must be low IQ for you to think people here can’t see or smell a troll.
At least wait until you have a few helpful or participation posts before trying, and failing, to fish for a circle jerk ********* on the phaser issue that ended in 2018 sans (go look up that word, I’ll wait) a few bad or old parts used.

I do have a 19 raptor I just like to mostly read about others problems my truck build date was 3/19 don't drive it much 1400 miles sounds fine now.I do have a back ground in mechanics,do you? Funny you think Iam a treasure retired truck tech 35+ years that likes to read about my new toy that's about it.

It’s the internet mate. I can say I have a master degree in automotive engineering and work for a major auto manufacturers power plant division as have 30+ years and own every model year of every raptor.

Wrong. You do not understand the operation of the system or the mode of failure. This has nothing to do with chain slap, skipped teeth, or chain guides.

The timing chain never loses tension; the issue is that the phaser locking pin can fail to engage, which causes the phaser vanes to oscillate until oil pressure reaches the cavity. The only component affected is the phaser itself.

Stop spreading misinformation.

Definitely an interesting mode of failure; was it making noise for a while before you brought it in?

The SSM is s still technically correct, as it is written to diagnose a noise concern without a Check Engine Light and associated DTCs. As you mention though, if timing related DTCs are set in addition to the noise, performance/longevity could certainly be negatively affected.
