Dealer or Rock auto. I generally dont let customers buy the parts.. However, in some cases, If the customer buys a part and bring it to me to replace it, I text them so its in writing, there is no warranty on my labor.. If it fails after install they are going to be paying me a second time for the repair... You shouldn't have to pay for the replacement parts....

I understand there’s no fault here, just manufacturing, I just don’t feel right charging him, a 65 year old man a second time for parts. On another note I have not been able to find the camshaft because I was looking at replacing it just in case the reluctor wheel is truly off bad enough, will a 2018 ford exploder 3.5 camshaft fit? I have one here in the salvage yard that I wanna go see if the camshaft is in it, if it fits I’d like to pick it up since the f150 camshaft is discontinued. If not I will have to replace the phasers and hope the reluctor isn’t badly off and it fires up fine.

Got the new parts in this past weekend, got all the phasers replaced, camshaft replaced, and the oil solenoid jumper harness (my ******* broke the wire pulling off the timing chain cover 😬
I got almost everything back together before it got dark, going to work diligently tonight to get it back together and back to the customer. I’ll keep everyone posted tomorrow on startup if the repair was successful or if I have to have it towed to a shop. Knock on wood everything is fixed and working properly. I got the gen 2.5 phasers like previously posted about and the new bolts to go with. Fingers crossed everything is a go tomorrow.

Good afternoon, got the truck back together and fired up, got it running, it was running smooth all the way until it went to idle, when it did the engine light started flashing and the truck started shaking so I pulled the codes with my scanner and the p0019 came back up again and a cylinder 1 misfire, cleared them, it ran fine for a minute then went back to doing the same thing again. I’m going to have to swap coils around in the cylinders to see if it fixes the misfire, but what the hell could be causing that p0019? Everything is brand new, phasers, chains, tensioners, gears, now a good used camshaft on ds exhaust.

good afternoon, I was able to get the p0019 code to go away, now I’m getting a p0017 code, which is the opposite side correlation issue, I’ve tried relearning the pcm in FORScan with zero success, tested the solenoids and they’re actuating, where do I go from here? I highly doubt that both camshaft reluctor wheels are off. Please please please any help on this thing. I’m almost half tempted to give him the truck back and have him take it to the dealer for them to reprogram or something, it’s bugging the crap out of me. If you idle it above a grand it idles just fine but the second it drops to low idle or running idle it is rough.

After I took and replaced the camshaft and cam phasers then put it back together the truck ran fine for about 2 minutes with everything back together then it started this p0017 code up. I tried to tap a battery on the connectors of the solenoids and they’re actuating, I wonder if cleaning the connector will help, I was reading on some other people’s situation and fixes for this same problem and they were saying they replaced phasers because the ones they got from ford were bad, one was saying that the solenoids weren’t actuating, and one was saying when you replace the crankshaft gear it is a good idea to replace the dowel pin because that will wear out causing the gear to move even a slight hit causing the computer to think the timing is off, and another was saying they pulled the valve cover and found the timing was one tooth off but had to advance it 2 teeth to get the code to go away, so right now I’m not sure where to start with this thing. The customer is coming today to pick it up because he needs his truck back, I told him he can drive it but it’s running rough at idle.

Without having my hands on it there is only so much I can do... The crank sprocket is softer metal then then dowel pin so I will inspect and sometimes replace the crank sprocket while apart if there is a dent in the keyway and its really cheap.. Single color links on the exhaust and intake cam phasers and the double color link splitting the crank sprocket.. The old style phasers are junk and fail usually in less the 60k, but having a ford one, old or new style, fail out of the box, I cant say that I've seen..
Letting him drive it with it running rough is going to damage other stuff.. .For example the cats.. P0420/430.. If you live in an emissions state youll have to fix those before it will pass inspection.. Not to mention other damage to the engine. I would advise not to drive around much with a P0017 or P0019.
What was the original issue you where fixing?

Cam phasers were bad, he had the real bad rattle on startup and acceleration, I lined everything up marks wise as well as notches on the tools. Could the solenoid be actuating but not enough or it be getting bad connection? I can see the items in FORScan and it shows no fault. But the ps exhaust camshaft is 33degrees and -33degrees.

The solenoid circuits are monitored by the PCM for an open, short to ground or short to power.... IF the P0017 or P0019 are all its setting then the pcm is just seeing the timing is off.... Maybe a stuck open VCT solenoid but I've never seen that on a 3.5 ecoboost, myself..
Are the solenoids OEM? Sometimes aftermarket is ok to use, but when its something Mission critical that is not easy to swap out its better to go with oem.. Especially those solenoids.. They are not a ton more expensive for the oem ones.

How many miles on this thing?
Just throwing this out there but oil pressure is lowest at idle and reading through the thread you said it runs good >1000 rpm and somewhere I saw erratic oil pressure mentioned.
Makes me wonder if it is an oil pressure issue. Be it debri or a worn out engine.
