What causes blue smoke from your car?

This depends:Diesel engine cold start, engine wear, damaged or worn injection systemGasoline engines display blue smoke from oil usage:If a puff of blue smoke on cold start, valve guides are leaking slightlyA puff of blue smoke after a deceleration with no throttle applied, valve guides are worse than he above example and oil usage may be starting to be an issue due to this.Blue smoke at idle and most times when the engine is at low throttle or medium throttle settings. This engine is badly worn or has been badly overheated damaging the piston ring sealCloud of blue smoke at high RPM high throttle settings. This engine has "Ring Flutter" and will require new pistons and rings to correct.


What exactly does RPM measure in an engine?

RPM means Revolutions Per Minute. This measures the amount of times the crank shaft goes around in one minute.


Does the engine work harder at low rpm or high rpm?

This will depend on what the "work" is. Example, if the vehicle is in neutral gear, on low rpm idling of course the engine is doing less work. But when the accelerator is pressed to rev up, then the engine is doing more work. Another example, cruising on a flat highway at high speed but engine's rpm is low when at top gear, hence engine is doing average work. But let the vehicle go up an incline and speed goes slow and the engine's rev goes high when on first gear, hence the engine is doing a lot of work.


When driving my car at high speed or RPM's somewhere around 4500 to 5000 I have checked my engine and for about a minute after pushed there is white smoke coming out from under the engine Why?

5000 rpm is extremely high unless you are drag racing in which case the engine is built to handle it and will be rebuilt often. otherwise white smoke usually means oil smoke, so you are pushing oil out somewhere. high rpm also means high oil pressure, how is your crankcase ventilation ,pcv valve, no ventilation will cause extra high pressure in the engine and oil could be weeping out of your oil pan gasket valve cover gaskets or engine seals.
