should i be using the pm22a in my new 2017 f250?

 

Try a can of Rislone concentrate .
my tick never returned.

 

Make sure it is not this -

SSM 47836 - 2011-2019 F-Super Duty - 6.7L Diesel - Reductant Injector Ticking/Tapping Noise
Some 2011-2019 F-Super Duty 6.7L diesel equipped vehicles may exhibit a ticking/tapping noise traced to the reductant injector. This noise is not an indicationof incorrect injector function and has no short or long term durability effects on the component. If the vehicle does not exhibit any drivability related symptoms or diagnostic trouble codes (DTC) do not attempt repairs. Credit Ford Service

I know what the OP was originally posting way back when and the TSB's from GM and even Dodge - just make sure to keep in mind that when you hear noises from your newer much quieter diesel, these two things:

1)The above possible additional source of noise and the metallic tick associated with the DPF heating during a regen on top of that
2) or that because these diesels are much quieter, you hear noises that always have been there but were drowned out by combustion noise which has been dramatically reduced. More and more use of pilot injection across all conditions plus higher number of multiple spray events have made diesels so quiet that you pick up other normal operation noises or actuator noises.

Another example for an example - on the Duramax when it first came out, the main initial reason why it was so quiet when it came out was due to pilot injection as many know. What many did not know was that pilot injection would get cancelled above certain RPM's due to injector limits, and when it was turned off, the engine noise would dramatically increase. It was in the area of above 3,000 RPM so a lot of people associated it with the engine having an issue particularly because it would happen under load at high RPMS.

Old news for many I know but illustrates a point being my truck makes all kinds of noises - and its caused enough of a concern among buyers that the big 3 keep sending out SSM's on it. Keep in mind there is so much monitoring now that if anything is off, it will cause a code and even de-rate the engine. If you had a mis-build and that truly was the source of your noise - the pending internal self destruction of your engine- it is a very rare occurrence and certainly not as often as the number reporting noise concerns.

The true way to eliminate an internal engine issue and to give you peace of mind, or build up case if you have a problem, is to perform regular oil analysis. The vast majority of internal engine problems will show up on analysis before failure.

****Disclaimer-There are no 'absolutes' and 'always' in anything I stated, nor am I coming down on anyone posting in here about noise concerns, just adding to the pool of resources on here and something to take under consideration.
**** and be careful with oil additives, they can cause more problems than solutions. I'm not saying don't use them but be careful - as I recall the recent last major engine repair I have had was a collapsed lifter from the owner adding a can of engine oil stop leak fixer to address an oil pan gasket leak. Another point is that if I did have an engine issue on my newer truck under powertrain warranty to 100K, I would not want to mask it with a can of additive and introduce additional variables.

 

^^^Good info bernie165. The metallic tick or clicking after a regen is really noticeable, especially after shutting off the engine when an OCR is completed. I ran an OCR a few weeks back and the tick from the extreme heating temps of the dpf is quite distinct. Of course, if it ticks when the engine is off, it's not the engine!
