My question just became a moot point yesterday. Accelerating from a standstill radio off, windows down and next to a jersey wall I heard a faint rattle. Knowing I had done a lot of work under the car yesterday I wasn't too worried initially. Out of caution I nursed the car home and got it back up in the air. With the girlfriend blipping the throttle I became fairly certain it was rod knock. After straining the oil through a black t shirt, degreasing it, and waiting for it to dry I found no bearing material. I then cut open the oil filter and separated the pleats. I found what I was looking for, each pleat had silver flakes all with small striations.

At this point I'm going to begin pulling the motor and split the case. I will update with what I find. I'm sad but happy. This motor should've lasted longer, between the conservative tune and meticulous maintenance. I never babied this car, I refuse to be one of those guys that do a pull a week. I look forward to the work ahead and the pride of starting a motor I had a hand in building.

I will continue to utilize the vast amount of knowledge available in this forum. Please feel free to offer advice, constructive or otherwise. To anyone local in the Hampton Roads area that would like to rent me some of the proprietary to Subaru tools required PM me.
