So I changed the oil today after about 2 months and 2k miles. I burned through an extra 4 quarts during that time which was starting to get bothersome. My oil pan drips a bit but not enough to leave a puddle on the ground every morning. It also smokes a bit on startup, but that's not unusual for a rotary.

I was starting to wonder why I was burning so much oil and today I finally figured it out. I noticed the control rod for the mechanical Oil Metering Pump was being held up in the mostly open position by a section of engine wiring harness held up by a misaligned bracket. That means my car was always feeding mid-to-full-throttle levels of oil through the oil injectors at all times, even at idle. No wonder I was burning so much oil, and that also explains why my plugs were getting so oil fouled before.

Examining the oil itself revealed a lot of metal particles, which isn't all that unusual on the first couple oil changes on a fresh rebuild ...but still if I still see that much metal in the oil on the next oil change I will be a little worried.

I was running Valvoline VR1, but now I am stepping it up to the real deal Idemitsu synthetic rotary racing oil w/ premix. I decided to disconnect the oil metering pump altogether and see how much oil I use by premixing instead.

I premixed my bridgeported 12A in my other FB so it's not all that new to me. I remember it burned less oil then this GSL-SE was up until now so premixing should help this 13B burn less oil as well. (And I damn well hope so at $10 a quart)
