What happens when you Rev the engine in neutral?
More common in continued over revving – the cylinder head & block doesn’t drain the oil at the same rate that oil is pumped out of the sump, leaving the sump empty, common in the Rover V8 engines. This is very common in engines that don’t have the minimum oil required.
Why is my Hyundai Santa Fe not turning?
If you’ve broken a drive/axle shaft, your Hyundai Santa Fe’s transmission has no way to turn the wheels anymore. If this were the case, there would not be any movement whatsoever from the vehicle. You also wouldn’t feel the slight jerk your Santa Fe as you put it into gear.
Can a car go from Redline to Full Throttle in neutral?
So my question is, on a normal street car with a rev limiter and wet sump, can any excess wear occur from revving your engine to redline at full throttle in neutral that wouldn’t also happen if you took it to redline in 1st – 6th gear? It is indeed mostly a rumor, but with some background.
How does revving an engine affect the engine?
Rapidly revving an engine will heat up the piston rings much faster. Because they have a much smaller thermal mass than the cylinder liners they expand at different rates. If the compression rings expand too much, they will generate increased friction on the cylinder liners, causing the cylinder liners to wear out (reducing compression).
How does revving the engine in neutral cause damage?
Some conrods will stretch/bend during excessive rpm acceleration. Worst case scenario is it will put greater unbalanced forces on the crankshaft and bearings (higher compression ratio only needs 10 thou). If the engine has tight tolerances it will also bend valves.

Why is revving the engine bad for your car?
Revving out the engine in your car can be bad for the engine if it’s internal temperature is still low. On a cold start, the internals of an engine hasn’t had a chance to properly warm up and the engine oil is still cold which means it won’t flow as well.
