Lots of damage depending on how long you can it with out oil.
The list is to long of things that could go wrong.
Drain out the excess oil and hope you did no damage. Unless you overfilled it by more than 1 quart you more than likely did not damage at all.
No, but you need to make sure that whenever you decide to run that engine in a car you have oil in it.
They are neither. Coal is a fuel which can be used to run motors and generators.
No. They simply won't run.
If the engine has been run without sufficient oil, there will be significant damage.
yes it does damage your car and your car wont run ; ]
If you run an engine without oil, the pistons will over heat, and other components in your cranckcase and parts that need oil can crack because of no oil. You'll spend big $ to get your car fixed if you run it with no oil.
The longer it runs the more irreversible damage will occur. Run it long enough and it will eventually seize up.
If you run the car without oil ..you have more problems than the injector rails.. you cant actaly damage them with lack of oil .. however ..you will cause the motor to overheat and seize ..you will also stuff he pistons and the block ..the crank shaft will be hot welded to the piston rods..the valves at the top of the motor will be stuck and they will be worn down ..running a motor without oil ..would result in a whole engine rebuild ..or the cheaper option of replace the whole lot ...DONT RUN THE CAR WITHOUT OIL ..
Yes it can but you risk doing more damage internally if coolant is mixing with the motor oil.
Depends on what you mean by "bad." If its bad as in low quality oil/filter it the long run it can damage your engine and in the short run give you less gas mileage. If its bad as in a idiot technician didnt tighten the filter or put the wrong oil, or not enough oil. Yes that can be very bad for your engine and damage performance.
damage engine no.. will the engine run no.
