  • F150 4.6 timing chain pics
  • Decided to tackle replacing the timing chain kit on the old F150. I have another truck for daily driving, so I've been tearing down in the driveway a little each day after work......

  • on a side note.....
  • Pulling the valve covers causes quite a bit of dirt, etc to break lose & fall into the works. I've gotten most if it with the shop vac, but I know there's grit the vac can't get out of the sticky oil. Any ideas how to get rid of it? Flush with some kind of solvent into the pan & do the usual oil change?

  • left side orig parts
  • Not much wear that I can see on these either. Based on the condition of my original timing parts I can't see where they were the source of my engine noise. I guess it's possible my oil pump has lost pressure & is starving the right side ohc(I think it is last in line for oil), but honestly I don't see much difference in wear or color from one valve-train side to the other.

  • original parts pics
  • I don't see any of the wear I was expecting to see. The tensioners were both still tight, guides unbroken.

  • Looks pretty darn good to me. What brand oil do you use?

  • 9 out of every 10 changes over the life of the truck were Valvoline. There was a year or so back around 150k miles I went through a synthetic phase, but the engine developed some issues, so I went back to conventional oil and things cleared up.

  • Contact your local Ford parts dept and see if they *possibly* have an updated kit with a few more parts in it.

  • I replaced a Windsor timing belt in my wife's 2004 with about 200,000 miles. The reason was the upper guide broke at the slide bolt. The tensioner took up the slack, and the timing was effected and eventually the catalytic converter clogged and the engine quit. The repair took a couple weekends. My recommendations is to chase the threads for the valve covers. My regret is that I did not replace with a short block, the engine following used oil through the valves or rings, and a short block was cheaper that the time gear parts, water pump, gears, tensioners, etc.

  • Re: F150 4.6 timing chain pics
  • That looks like a real project! Good luck with that.
    How many miles do you have on your f-150?
    It is just like my 01 expedition's 4.6.
    The good thing is that by the time you are done, you will be an expert on replacing those.

  • Turned over 225k this year. This truck has a Romeo 4.6 whereas my Expedition(same year)has a Windsor 4.6.....quite a few differences. Generally, the Windsor version is more heavy duty.

    One thing about this era of the Ford trucks, those back cylinders you have to practically climb through a tunnel to get at.
