also, instead of feeling the engine hood you could just use the temp gauge, alot easier and more accurate
Yeah its bad you should wait till its completely warm to do any kind of revving
It isn't damaging as such but does increase wear on rings and cylinder walls etc.
Engines are tested for this over many cycles and extreme temperature variations before production release. No manufacturers wants to see failed engines in any climate or standard use.
There is a very slight risk of course with new engines but very very minimal.
Yes it will increase engine wear.
Once you start an engine you need to give it time for the oil pump to circulate lubricant to all parts of the engine. Over rev it before this has happened and you have bare metal parts rubbing together at a much higher speed than normal. Metal on Metal causes friction; friction causes heat; heat causes metal to expand; expanded metal seizes.
Why do you want to do this anyway? it sounds bad and makes you look a prat.
Hi so consult with a car dealer as it could be a number of problems which they could so easily fix.
is it bad to rev an engine high (near redline) on low engine temperature ? I dont mean a complete cold start, I mean starting the car when you can feel the hood warm from a warm engine but the temperature gauge doesnt show a high or an operating temperature that you would usually see on the motorway i.e about 90 degrees celcius.
