Pecking sound after oil change

[DavidPhillips]

The older powerstrokes injectors were controlled by extremely high oil pressures and would experience some injector noise due to oil.

These things have electronic injectors and the oil is not doing anything at all with the fuel system.

It does sound like your describing injector noise though. Did they change the fuel filter?

[lherronjr]

no just oil and oil filter.

Yes, I am going to call the dealership where I purchased the truck and take it there. It is just a little longer drive now since I moved about 40 miles away. I am very unhappy with this dealership I went to today

Getting my oil changed tomorrow.

Hope everything goes well. Do you use any fuel additives to keep your injectors clean? I dont know what I can use. How many miles do you have on your truck now?

[DavidPhillips]

I have 5,000 miles on my truck which was mostly from three 1400 mile trips all highway and very easy driving, 200 miles of towing, and the rest were miles around town and local highway and interstate.

I have not used any additives. Ford does not recommend anything but cetane boost only if needed. I have a case of Stanadyne additive I use in my 6.5 Chevy. I have been reluctant to use anything with the warnings about injectors in the Owners Manual Supplement. Not too sure what it would do to the DPF either. I have read some stuff about an additive for DPF exhaust helping the regeneration but what is it going to do to the injectors?

I am probably going to stay with nothing added.

The old 6.5 loves it. Different animal though.

Well, the truck is at dealership since Thursday morning. Navistar paid to have two engineers flown in today and they spent 7 hours on truck. replaced injector at cylinder 5 because they think they have the noise isolated to cylinder 5 but this did not fix. the engineers said they did have a few engines from one of the engine plants that showed premature camshaft lobe wear and they think that might be the issue with my engine. they will be deciding what their next step is Monday. I am going to push for a new engine so they can just take this one and research it to prevent future issues. Man am I depressed, I want my truck back now! They give me an explorer to drive while truck is in shop. I hope they dont tear my truck up while trying to repair it. Pray for my baby!!!!!

It is most noticeable from underneath truck. The pecking is not real loud but sometimes louder than others. Thanks for the thoughts and prayers, hope he comes home soon.l
