My youngest son's truck died pulling into the driveway. Motor seized. No oil pressure at about 2 or 3 miles away. I really don't know how to get it through their head how important oil is for an engine. 2006 F150s are super easy to pull the pan on.
Reason was the camshaft sycronizer drive gear on end of camshaft wore away. (This doesn't make sense, I suspect crappy aftermarket cam syncronizer assy gear.)
Found 2 rod bearings froze to crankshaft fed by the main crankshaft thrust bearing. Emery clothed the aluminum off of the crank shaft (this worked really slick). Rod journals looked perfect on one and good enough on the other.
It got hot but didn't discolor any metal, just blackened the metal from the oil it cooked. Think this helped by lower residential speeds.
Pulled the thrust bearing out, cleaned oiling holes to rods, replaced bearing as it was getting chewed up, crank looked fine.
Found the gear at a pick a part as they are not made any more. (Surprising number of hits on google with people needing this gear)
Put back together and we'll see what happens, initial couple starts with no coolant it had a tick and what I thought was roller lifter screech. However, went ahead and put all the crap on front of motor and antifreeze in and sounded perfect when pulled out.
20 mile oil change had some the aluminum from the toasted bearings coming coming out, see how much is there at 500 miles
This is a beat to hell pickup that didn't deserve any time or money, but it got a couple hundred bucks and way too much time cause I'm curious how long it will go, or if it even would!
Factory fuel injection and modern oil is impressive, the journals of the thrust bearings still had fine finish from the turning of the surface. They could easily go another 200k miles if you keep them lubed. May help these v6's are not a powerhouse by any means.
