164k religious 5k oil changes with full synthetic.

Was driving today and suddenly engine locked up. No drop in oil pressure, plenty of oil on the dipstick,no overheating. No check engine lights no nothing until it locked up while diving then the low oil pressure light flickered. No crazy ticking, no loss in power. Just sudden engine seizure. Took the belt off, didnít help, pulled 3 plugs, no change.

Starter tries to kick over the engine and it rocks in the engine bay. Got it towed to a local rebuilder that has done 5.4 3vís in the last week. This truck has literally never had a problem outside of a wheel bearing!

What gives?

Long shot guess would be timing chain also.

It would be nice if you shared more info about the oil, like weights and brands.

Pull all 8 spark plugs! Pulling 3 random ones doesn't mean much.

If the engine rocks in the engine bay it wouldn't be the engine that's seized you wouldn't think. In order to rock the starter would have to be torquing against something in the driveline, if the engine is completely seized there should be no rocking.

Just a theory.

Sorry to hear...it will be interesting to hear what the mechanic finds.

Speculate the main bearings. Or timing chain. Or both.

This. I would look at the transmission before the engine. A seized engine will only make a ďclickĒ sound and no engine movement. With no warning or noise I find it hard to believe the engine is the issue.

I'm guessing driveline not engine also.
