OK, then you need to start looking at other suspects. There are a series of hammer in plugs, much like freeze out plugs, in your engine's oiling system; one of these may have popped loose. It find it without taking the engine apart (which you may end up doing anyway, depending upon where it is), you need to connect an oil filled pressure chamber to the oiling system and then pressure the oil backwards into the system, looking for where the oil comes pouring out.1 point

You will have no oil pressure, which is also what you would have if something was holding the piston off its seat. If you pull and open the oil pump cassette, you can inspect the gears for pitting or chipping, which would also reduce or kill oil pressure, and check the oil pump drive shaft which is an investment cast piece that is well know for failing. If the drive shaft has crapped out, LN engineering sells a chrome moly replacement that will outlive the car.1 point

You need to look at your oil pump, particularly the pressure by pass assembly. If metal was circulated, it could have either destroyed the pump gears or jammed open the by pass.1 point

Oh, one more thing, you could also consider buying/building a 991.2 and add the PowerKit. This may give you more flexibility, and an available open build allocation. I did this back in 2014, since the GTS was not released yet, and I wanted the extra 30 HP of the PowerKit. It was expensive, thought, at about $18,600. The 991.2 PowerKit is about 1/2 that price. Good luck. Fantastic cars.1 point
