4.6L 3V Triton Questions
Good day to all!
I just had a few questions for anyone out there that was very knowledgeable about the 3V Triton engines, primary the 4.6L 3V used in the 2009-2010 F-150's. I own a 2010 F150 w/ the 4.6L 3V engine and 6R80 Auto. It has 160k miles on it currently. I have always changed the oil w/ Motorcraft 5W 20 synthetic blend and STP "blue bottle" oil treatment every 3k miles. The truck has been very well cared for both mechanically and cosmetically so I am doing everything in my power to make it last. The truck reached 10 years of age on 12-8-19 according to it's production date (12-8-09). My goal is to keep it running another 10 years if possible. Anyway, I have a few questions that will help me determine what i need to do to insure that it does.
First, I need to know if it is necessary to replace the timing chains, phasers, adjusters, and guides or if i can wait? There is no "rattle" on start up or unusual noise from the phasers or roller followers when running. The engine sounds very healthy and runs like it did the day it was new. I know from 2004 up to about 2007'ish the 5.4L 3Vs were having lots of issues with phasers and timing chain tensioners failing. I know Ford "revised" some of these components around the 2007-2008 model year so I'm hoping my 4.6L 3V has the "revised" parts? I know it has the "revised" tensions with the improved gasket design but not sure about the other components? I'm just wondering if they could potentially last over 200k-250k miles w/o having to replace them? No need to do it if it is not necessary.
My second question is concerning the oil pump. Does anyone know if the oil pump in my truck would be a "revised' version from those that were failing in the 2004-2008 year trucks? Or, is it the same exact one? In other words, did Ford ever acknowledge there was an issue with them in the 3V's prior to 2010 and do something about it? If I find out it is the same, I intend to change it in the very near future. I'll wait if it's an improved version, however.
My final question. Is there anything I should be concerned about with this engine now and in the future aside from what I mentioned above?
Thank you for your time.
