The 3v is a turd. The 2 and 4 valve motors were great.

I guess it didn’t have enough power to break anything. |

I rode shotgun in a Uhaul with a 5.4 from Haines to Anchorage. Soooooooo gutless. |

They got swapped into weird stuff but nobody was ever super happy about them. I’m sure they don’t share much but the Lightning and GT used a 5.4 variant. |

The 5.4 has several design defects. Hope the one you got had oil changes every 3k miles otherwise welcome to the sludge factory. Even with regular EARLY oil changes most of them get the upper oil passageways clogged up by 100k miles and the only real solution is a new engine. Ford really screwed up with this one.
Good news is there are experienced mechanics who can do a new 5.4 swap with a factory reman engine for around $6k since it's such a common thing. |

I am going to remove the oil pump pick up, then I am going to use my diesel pump to keep pushing diesel through the oiling system until it gets all the sludge out! |

Upgrade the oil pump if you’re going to be towing. The oem pump looses pressure at high rpm.

I've towed with the 5.4 and it wasn't bad at all--it's a truck engine. Well except the gas mileage.

My dad had a 34Ft moton home with the v10....he put like 80k on that motor home and dogged the living shit out of that engine out west and in the mountains. Engine was like "THANK YOU SIR CAN I HAVE ANOTHER!" |

You could just swap in a good old 7.3 Godzilla ..that should make it better...

If you listen to fortechmakuloko, he will tell you a melling high pressure oil pump will solve all the oiling problems.
I had over 100k on mine when I got rid of it, and never had that issues. The exhaust manifold rotting out was the biggest loss of power. Had them replaced and that thing ran like a raped ape. However I do agree that overall, that may be Ford’s worst engine ever. |

The 5.4 can barely carry it’s own weight…sell it, get something else.

You've got $1500 in it, and it RUNS... the SMART play is to sell it for $1501.
Quick, take your dollar and RUN. |

The first thing you should do is put a real oil pressure gauge on it and see if you have any oil pressure at idle. The dash indicator is completely worthless don't trust it. If its within range swap the oil pump for a Melling high volume pump and you might save it.
I've heard of folks running a heavy weight oil to mask the issue for a while. I dumped 6K into the one I had due to having 0 oil pressure at 140k miles. The motor that was swapped in supposedly had 90k miles. I had the upgraded pump installed and it suffered the same low oil pressure fate less than 10k miles later even with an upgraded pump. <<<<<< Former owner of a 2010 F250 4x4 5.4L 3V. |

I had three 5.4 Tritons do over 300k miles each. Our V-10 Triton shot craps at 200k
