I have a 2017 F150 V8 that I purchased used in 2019 with 27,000 miles. I have properly maintained the vehicle and it now has 59,800 miles. Last September I received an alert of a intake manifold assembly issue. I couldn't find the part anywhere so I had a local Ford dealership replace the part. Recently, the truck dies while idling at a red light after the engine is hot, so I scheduled a follow up with the dealer assuming it was related to the manifold replacement.
Much to my shock they told me they recommend replacing the long block (not available for at least 9 months!) due to bearing issues causing the oil pressure to drop below minimum specifications. Here are the notes from the tech:Verified customer concern engine would stall when idling once engine has reached full operating temperature. Checked DTC’s found p0012 stored in PCM, found SSM 50067 related to concern. Attempted to clear VCT unable to maintain position solenoid manually, condition did not improve. Monitored VCT PID data found bank 1 intake VCT position erratic movement. Checked engine oil pressure below minimum specifications. It is recommended to replace long block assembly as no short locks are available. And no internal repairs can be performed.

Does anyone know if this a known issues with this model? I am open to suggestions for responding to Ford or for a rebuild. I have owned over 25 cars in my lifetime with many exceeding 200,000 miles and have never encountered an issue where a engine replacement is recommended.

TIA.

 

I'm guessing that you do not have the extended warranty, and if it was me paying for it out of pocket I'd be on the hunt for a low mile wrecked '17 that I could buy the engine/Trans out of.

 

Agreed Did they give you a price?? $10k??

 

I have Ford building me a new V8 (can't keep in stock here in Canada, apparently) I had the dreaded rough idle and stalling issue. Replaced the solenoids which fixed the stalling but not the rough idle. Two mechanics looked into it and said I have a 65% exhaust leak in number 8 cylinder. $12K for the engine with install including fluids, plugs, etc.

 

No extended warranty. They quoted me $11,500!!

 

Take it to an independent shop for a 2nd opinion.

 

This sound very suspicious. By design the 5.0 reduces oil pressure when hot at idle. If the oil pressure is too low the PCM would throw a code and your oil pressure gauge would read low. Using Forscan one could monitor the oil pressure and at hot idle it is around 10 to 12 PSI. Also, make sure you use the correct oil, 5W-20 Ford Synthetic Blend.

Probably the only thing you need to do is replace the VCT solenoid(s)…

Hard to believe at 59K miles the bearings would be toast. I would hook up Forscan and monitor cold start and hot idle oil pressure. They should be > 60 PSI cold and around 10 to 12 PSI hot.

 

Yep, I plan to do that.

 

Yes, seems very suspicious to me as well. It never threw any codes after it stalled, so how did they get to the point of engine replacement without any codes?!! They quoted me $3k to replace the VCT solenoids. Next step to is take it to an independent repair shop for their opinion.

 

OK, this dealer is crazy. Replacing the VCT solenoids is a very simple procedure. I do all my own work so I don't know what the dealer charges but surely it's less than $1k.
