TahoeBilly2007: Mine sounds like a Singer sewing machine at 172K. I used Marvels for a few oil cycles using full synthetic around 100K. I think the Marvels really cleaned things up now I run full synth every 10K.
rumerboyz: how many miles were on your truck when you replaced the motor? I have a 2005 F250 5.4 with 40,000 miles. Should I be worried? I change the oil every 5000 miles like the book says. Thanks for any info
javier solis: no buelvo a comprar freaking ford they run like a freaking burra
UBBERTANKER: the 3v ones dont pop plugs thats a 2v thing the 3v its impossible to get the plugs out without breaking them
Richard Bonillas: I have an 05 F150 Crew Cab 5.4L 3V, it is still running great and strong and the truck has 188,040. This is damn good engine ever I have so I always take care of it to maintain routine every 3,000 miles for oil change Motorcraft 5W20 and Motorcraft oil filter no problem at all since I bought it. I have noticed there are many 5.4L are crap because they don't take care of these engines.
Derrik Nikkel: Mine is a 05 5.4 v3 with 138000 km and same old crap I have seen so many others with same problems
tyu ytfgh: my dads 2001 ford f150 with the same engine has 250,000 miles and still runs perfect
lizard2006: @rondotrailer no it is not. That is clearly the cam phaser... 1100 dollars a side. the injector does not make that noise.
mifan93: i think its the lifters, all of the 3v 5.4 sound the same
rondotrailer: I know what you mean.
Actually it's the noisy fuel injection.
This motor is known for being noisy.
