I made the mistake of trying to make a green light by revving up my
CRV-2004 engine to about 6-7K rpm mark in 1st gear from stop (I have a
manual 5 speed). 6-7k is slightly above the red line. I didn't have the
time to change gears. The light was changing. I revved it up to that
level at a steady pace - I didn't gun it.

Is it possible that my cylinder walls are damaged and robbing me of
compression? Hairline fractures in my crankshaft? Any damage possible here?

Thanks
