Is it Hurley seals? I had the same experience a year ago when I used Hurley Racing Tip Seals in my rebuild.. After 500 miles it suddenly started to sound like a v8,and the engine lost alot of power. I managed to limp back home, to find out I had very low comp. on the rear rotor. 2 apex seals was broken, the rotor and housing where trash.. It looked like the the area of the apex that`s exposed to the ex. port, just had broken off in 1-2 mm high pieces. Both of the seals had the same damage, and the ex.port hardly showed any sign of it..One of the seals was missing a 5mm long piece from the middle, I found it stuck on the rotor face. It had dented the rotor and trash the housing. the rest of the seal was stuck in the seal groove in many pieces. Both the chambers had strange wear pattern between the spark plugs.
The engine was run in with no boost,never over 4000 rpm and 1% premix in the fuel,it was given special care and then it just "popped" for now reason..

Ted, what about the oil could do that?
To thick, to thin, not enough, no pressure?
