When that happens (because the oil pump gear is harder than the camshift worm), the camshaft gear (and the camshaft) is destroyed. Happened twice with my older Accord -- filling the engine with metal chips each time...
I haven’t had that problem. I replaced the front axle for 75 bucks and changed the tranny fluid which IS a definite requirement for these guys every 50,000. Timing and hoses every 100,000.
