Does red lining cause damage to the engine?

  • TOYOTA CELICA

Hello, I own a 1995 Toyota Celica 1.8 ST. The mileage is at 76,000. The red line begins at 6,400 rpm and ends at 8,000 rpm. In the morning I was driving to work and I forgot to change the gear to second. The engine was not fully warm. The rev meter reached to 7,500 rpm until I noticed and changed the gear instantly. I would like to know if this may have caused any damage to the engine? If so, what sort of damage? Your help is much appreciated.

Many Thanks.

Anything internally-you're dogging it-maybe someday it will throw a rod then bingo new engine is needed.

Thanks for the fast response. What is the likeliness I have caused any damage to the engine? If any damage is caused, how will I find out?

When it starts making wierd noises. Normally it will come from the lower end of the engine-a lot of pounding is being done down there. Bearings/Caps

Is it guaranteed damage? Or if you stray into the red-line, there is a likeliness of damage?

Dogging it, is where you're straining it, making it do something when it not suppose to.
