The Nubira did something weird during my trackday yesterday. Over the course of the event (30 minute sessions) there were no signs of trouble. The dummy light never came on, I never heard or smelled anything funny, the engine seemed strong (or at least no more weak than it normally is). When I pulled into the pits for the first session I left the engine running to cool down and pulled the dip stick to make sure there wasn't anything funky in the oil. No problem.
After about 7 minutes of cool down idling in the paddock I checked the oil level and it was fine.
During the second session I pushed a little bit harder and spent less time stuck behind slow people (which is saying something if the guy in the 1.5L Daewoo thinks you're slow). Still nothing bad from the dummy lights, no smells, temperatures are fine.
Then I pulled into the pits and stopped to BS with my buddy. The engine was idling or below 2k rpm (cruising through pitlane) for about two or three minutes when suddenly the dummy light flashes on and stays on for several seconds.
What the hell?
I go to the paddock as gently as possible and leave the engine to cool down again. 10 minutes pass. I check the oil and the level is fine, there's nothing bad floating around and the color looks brand new.
So again, what the hell?
Upon further inspection I did notice some oil splattered on the bottom of the hood, but I can't tell if it's coming from the dip stick tube or the cap on the valve cover.
I have a re-circulation system that vents to the intake, so I don't know how the crankcase is getting so pressurized.
