I have not, I will look into this and research it. Thanks for the heads up.Keefer- have you modified your oiling system? Just thought I would ask as that could be a big issue later this spring/summer for you. LN deep sump/skid plate and 996 water/oil heat exchanger along with a 3 radiator. You still could get air ingested in the oil from the heads, but if you are not using slicks, you should be ok. A Porsche 987 MotorSports AOS should also be installed to keep the oil from invading your AVOMs air filter and everything in between (MAF, throttle body, plenum and all the tubing). This has happened to me twice with the OEM AOS before I changed to the Porsche 987 MotorSports AOS.
