BEST OIL FOR 5.4 Tensioners?

[Eightiesrock80]

I’m wondering what is the best kind of oil to use if your timing belt tensioners lose a little bit of pressure causing timing belt to rattle a tiny bit at start up

I use 5W-30 because it feels right and Ford Tech Makuloco on YouTube recommends it. Chances are the tensioner seals leak—I pulled everything apart at 100K miles and both tensioners seals were compromised. The evil is chain slap on the plastic guides at startup over time will cause them to crack and crumble. Mine is an 06 now with 123K miles. How many miles on yours?

2003 Ford expedition two valve I had the heads rebuilt and the guy that did it was supposed to put new chain and belt tensioner‘s and guides but apparently he didn’t or this wouldn’t be happening I just hit 200,000 yah ford mulikoko is great his names Brian he’s from my neck of the woods s/w burbs of Chicago my names Jason nice to meet u I’m watching Brian’s video tonight on a three valve. I’m thinking about attempting to do it myself. If you don’t do something yourself, it will never get done, right

I get the tiniest bit of rattle on start up on my '03 when it's been sitting overnight. What I do is hold the gas pedal to the floor and crank the engine 5 to 7 seconds to build up a little oil pressure, then let off the gas and it starts without the rattle. But it's relatively low mileage at just under 92k.

So if your foot is all the way to the floor, it won’t start?

That is correct. Also, replacing the timing on a 2V is definitely some work, but is doable. Lots of nuts and bolts. Good chance for you to replace alot of the hoses and the water pump while you are in that deep.
