I changed the oil in my BRZ. Boneheaded move - I left the oil filler cap loose.
The cap came off, the car was driven around, and oil flew out everywhere in the engine compartment.
I lost slightly over a quart of oil. So by the time I noticed, the oil level was probably around 4.6 quarts. Car was not driven hard, mostly street driving with the missing cap. Questions:
1) Do you think I did any damage due to the low oil level?
2) What about any damage from driving with the open crankcase? Oil/air was blowing out the oil filler hole. Don't think anything got inside due to the outward pressure, but I changed the oil and filter again, just in case.
