Less is Better
In tracking down a rattle at idle, i took off my belly plate and found some very small oil drips at the front of the engine. The car has never dripped any oil at all, mystery. Fixed the rattle (don't follow Inokinetic's instructions to change the location of the shift cable hanger, it interferes with the NACA duct) and cleaned up the oil but couldn't find the source. Nothing obvious...until I opened the engine lid. The filler cap was MISSING! I must not have tightened it enough. It must have come off near the end of my drive yesterday because there was still plenty of oil in the pan and there was some on top of the engine and on the bottom of the engine cover, but not much. I could buy the stock cap for about $30 (the Toyota version is only $10) or get an aluminum one for about the same price. So I ordered an aluminum cap even though I don't particularly like aluminum caps. They get too hot to touch where the plastic ones don't. I wish someone made a CF cap.
