Some people tell me don’t change unless I go to 750+ horsepower.
Others have told me that their gen 3 Coyote gears let go, and destroyed their engine, even though they were stock.
I’ve also been told that at some point, Ford upgraded the quality of the oil pump gears in the generation 3 coyote.
So which is it?
Thank you.

I got mine changed when we did a full timing components refresh with the ford performance kit along with the oil pan, water pump etc. I put a boundary pump gear in and used the crank sprocket in the Ford kit.

I would not worry about it failing out of nowhere- especially on a road course car at stock power. I think its worthwhile while the timing cover is off and its all opened up, but wouldn't worry about it.

FWIW this won't be reassuring but I've had an unlucky friend blow 2 different gen 3's on track in his M1, but neither of them were OPG related.

Lost some 3 engines... memory has blocked the exact amount for some reason. None have been OPG or pump related. But definitely oil cooling and line size related.

OPGs aren't really that much of an issue, the crank gear can be but only if you're hanging a supercharger off the snout of the crank or banging off the rev limiter constantly. It's an overstated problem but a fairly easy 'while you're in there'

If you do upgrade, make sure you compare the timing mark index compared to your stock crank gear before your install it. I read on a forum (could have been here, maybe M6G) of people ending up with Boundary gears with the timing mark off by multiple teeth. It would be a total drag to build it up and have to redo it because the timing is off. Mine was marked fine, so most are probably ok.

Absolutely zero reason to replace OPG if you're engine is completely stock (or even are running the tune) - unless you're already getting in there for some other reason. There are stock cars ran much harder than most people will ever run them and they're completely fine (like Sam Strano's who runs his Mach 1 on multiple track in addition to autocrosses).
