On the outside? nota lot. it will heat up and probibly burn off in hot areas of your engine and cause a little smoking in your engin bay. but the rist will mosty drip off, how much oil was it?
If air or fluid was getting into the oil passages. Is the oil looking "bubbly" or "milkshake" like? Then coolant is getting into the oil, either by head gasket or somewhere else. If it smells gassy then fuel is getting into the oil.
Yes prolonged contact with motor oil can cause cancer.
It would probably clean out the gunk from the motor. It could cause the oil to lose its viscosity and cause a bearing to fail.
you have lost your oil cap
brake fluid doesn't have the viscosity that motor oil does and it will not lubricate engine parts properly. It would definetely cause some major damage at some point.
Low oil pressure in itself will not cause the motor not start. Low oil pressure is a cause for concern as far as motor lubrication. Low oil pressure can cause lubrication failure and be harmful to all moving parts.
It depends if you are getting oil to engine or not. When you start motor do you hear a clattering on the top end of motor. If so, then you indeed probabably are not getting oil to engine. Easy way to tell also is pull off vale cover and see if you are getting oil to top end of motor. believe me, you will know if your are pumping oil, it will be everywhere. If you are getting oil then probably oil pressure sending unit is bad. If not, then oil pump is bad.
Your motor oil going bad would cause that. That is in the crankcase, not the transmission.
the oil pump in the oil pan is bad, or worn bad enough that it no longer can push enough oil
NO
You may need to replace your oil pump.
When you bottomed out the car you could have hit the oil pan. When doing so you hit the oil pump and the oil is not getting to the motor correctly. That is what would be causeing it to over heat or run hot. But the skipping I dont know.
