I found my oil cap left off (in the engine bay by the battery) after an oil change. car had been driven less then 45 miles & 1 day later (GARAGE KEPT) till I found this and put the cap on tightly,,,,,what would be the worst damage if any from this. Yes, I am a dumbass considering this is the very reason I change my own oil/filter myself AND I do something this stupid.

 

I guess the worst thing that could happen is that something could fall down into your motor and trash it.

However, in your case, I think the worst thing that happened is that oil splattered onto your hood and other under-hood components.

Check your oil level and clean up the splatter.

If you're really concerned about it, do another oil change. (but I wouldn't go to that extreme)

 

Boy, the worst that coulda happened...

probably posting it on a message board & having thousands of people giggle at yer simple mistake and the resulting worry

Dont sweat it.. we've all done something like that... clean it up.. forget about it.

 

nothing could embarrass me more then what I did. I can't do much mechanically but change the oil every 3,000 miles and now I screwed that up....Thanks, I tend to overeact cause I love this Z28 and want it to last and run good a long time

 

I wouldn't worry about it. Like what was said..clean up any splatter and continue to enjoy your baby.
