Too bad man. Sounds like you could have really had a good driver. Good luck. Maybe you can find a fair priced replacement engine if you like the body and interior.I recently acquired a 2004 Lincoln Navigator with the 5.4L Intech 32v engine, 141k miles. The engine was having a misfire (0306) on cylinder six, and P0171 on bank one.
I changed the spark plug and the COP on cylinder six, but still had the misfire. I replaced the PCV and related hoses, and the P0171 appeared to go away. Misfire still remained, but would take a while to show up on the scanner. The SUV idled poorly, but seemed to run fine at highway speeds. At 4am this morning, I went to inspect all the vacuum lines with a flashlight. I discovered the what I believe the crankcase breather hose the goes from the engine to the air filter was not connected. It appears the hose was off for an extended amount of time. Leaving a opening to the engine. No oil or any debris was showing aroung the opening, just a lot of dust and dirt.
After connecting the crankcase breather hose, I decided to go on an early interstate test run. About 15 miles into the run, at a high speed, the low oil pressure light came on. I was unable to pull off the interstate, and slowed down and made it to an exit ramp. On the exit ramp the engine made the sound of metal on metal. I pulled over, and checked the oil. It looked overfilled. I checked coolant level, no change in its level. I had my scanner, no misfire on cylinder six. no P0171. But had a new code, which I cant remember but it was something about to much fuel getting to a oxygen sensor.
Called a tow truck, and had the truck dropped off at a local shop, and I took a uber home (I have no driveway).
I suspect the engine had a catastrophic internal failure. The engine will turn over, but not easily. It will try to start but does not.
On a side note, I am aware of the same engine in a 2004 with 120k miles available for $450, but I have to pull the engine and the SUV is smashed and in a field.
This is a DOHC engine, not the 3V SOHC one. It's the big brother of the 4.6L DOHC engine found in the Cobra and Aviator and was loosely the bases for the 2000 Cobra-R engine.Because of the oil pump leak, phaser and tensioner leak issues with this engine, it’s not a good idea to use thin oils. M1 HM 10w-40 is correct for an older version of this engine.
A local Ford dealer went to 10W-40 immediately, to stem the tide of phaser, cam chain and audible knock issues. Problem solved. I've been using 10W-30M1 when new and 10W-40HM from about the 100K mark. Now pushing 200K, engine runs perfectly. And it gets abused beyond belief.
Sometimes those kind of guys (covered in grease) are that way cause they have so much business they barely stop. Cross your fingers.Just a quick update.
I purchased a used engine in Lumberton, NC. The used engine has 120k miles on it, and a carfax history showing regular oil changes.
Regrettably, I hired an independent mechanic local to Lumberton to remove the donor engine, replace timing chains, plugs, coils, intake manifold gasket, valve cover gasket, egr valve, and heater hoses. Replacing the heater hoses and egr valve as they require the engine out or the intake manifold remove to replace those two parts.
I towed the Navigator (200 miles) to the independent mechanic and after meeting him, I have zero confidence he knows what he is doing, or that I will see the Navigator on the road again. I sure hope I am wrong, but that is my gut. The mechanic had a helper, both of them were FULLY covered in grease. I sense I know considerably more about the 32V engine than the mechanic does- and I know very little.
This is real life. Sometimes its magic, sometimes it tragic. I sense tragic on this one......
Still, it's his time and money to spend as he chooses. Although, yeah, I'd personally walk away. This whole era was Ford trying too hard to be unique with their motors solely for the purpose of being unique. GM was laying down just as good or better power and mileage with pushrods.....He is getting ready to make a 3,000 mile cross country work ordered move in like 60 days and is spending time chasing junk motors for a vehicle that was in a junk yard to begin with.
D60, that is the issue. When I brought up a few things about the vehicle, and the engine in particular, he seemed lost. Being filthy dirty I can certainly understand, and have been there myself hundreds of times. Being filthy dirty AND not seeming to know anything about the SUV and its engine.... that is what raised my alert level to be very worried.I'd judge a mechanic more on if he knows the nomenclature and seems to understand it. Of course even that isn't necessarily a perfect metric....
....still, if you start talking cam phasers, hydraulic tensioners, HV oil pumps and he looks confused, yeah I'd be scared then.
That said, I have NO idea how these engines vary from the 3V 5.4? Are they considerably different?
Regrettably, I hired an independent mechanic local to Lumberton to remove the donor engine, replace timing chains, plugs, coils, intake manifold gasket, valve cover gasket, egr valve, and heater hoses. Replacing the heater hoses and egr valve as they require the engine out or the intake manifold remove to replace those two parts.
Sounds like a Simon and Garfunkel song..........(we are the rock we are an island...).Sometimes we are the BUG, sometimes the WINDSHIELD!

The Modular engines (minus the 3V) were generally extremely reliable and long-lived, their service record in the Crown Vic, Grand Marquis and Town Car in LEO/Taxi and Limo service is extremely well regarded as is its service in the E-series vans. The biggest detractors over the SBF they replaced and the LSx was physical size. They are physically much larger for the same or smaller displacement.Still, it's his time and money to spend as he chooses. Although, yeah, I'd personally walk away. This whole era was Ford trying too hard to be unique with their motors solely for the purpose of being unique. GM was laying down just as good or better power and mileage with pushrods.....
