Yep. My 2002 Navigator 4-Valver calls for 91 octane.
But with knock sensors it runs fine on 87 octane.
Only thing I notice when running 91 octane is better part throttle response and maybe 0.5 mpg improvement.

The point of my post referencing the 91 octane spec for Navigator trucks, is that even when Ford made the switch to the 3-valve engines for both the Navigator and Expedition in 2005, the Navigator still called for 91 octane even though both were now using the same engine.

Yea as far as I can tell the engine is very clean and seems to have been well kept. I may pull a couple cam caps off but I don't expect to find anything out of place.

Not that I did much today but I did flip it over right side up. I spun the engine over and it lukily has not jumped time. Hopefully my buddy will ring the timing chain tools tomorrow.

Ummm, what timing chain tools? In my years of working for various Ford dealers since 2000, I have never needed to use any tools to time any 4.6/5.4/6.8 engine. I simply fold each chain in half and align the two copper links to cam sprocket alignment mark and the single copper link to the crank sprocket mark at the 6 o'clock position and we're timed. That is unless you are referring to the tool that secures the crank?

As it turns out the tensioned side was worn badly also. I am very surprised for as clean as it is inside.
new hardware installed. Tc installed, manifolds removed,clean surfaces,new gaskets,studs,nuts torqued to oe spec. These suckers had better not leak..

I need a drain plug,oil,filter and a few tidbits installed tonight and it'll be ready to stab in.
im hoping tomorrow night to shove the body back in and work at pumping the fuel tank empty of the nasty old fuel.
