Go to home depot and get a 6 inch piece of pipe. While idling, listen to each valve through the valve cover. If you bent a valve, it will have a pronounced "tick" that the others do not have.

 

I Did the same on my 2G DSM, thrrew it into 2nd at 100MPH, 12,000RPMS< no damage.

 

damn damn damn....you guys are one lucky SOBs, heard about the RSX ?? dood blew up his motor and tranny

 

my friend was was driving down the highway in a 99 civic and told the kid in the passenger seat to throw it in fourth and he through it in reverse and then engaged and said it was the loudest grind he ever heard and i can't imagine what rpm's it went up to.

 

AAAHHHHGH! This thread is hard to read.

 

The gears probably didn't engage, which would explain the loud grinding noise. Most reverse gears don't have syncros or only have a single one for smoothness, because they aren't meant to be engaged at an rpm too much higher than idle. Definitely didn't do his reverse any favors, though...

 

I know of a guy who did the same on his 1G DSM. His head & valvetrain was all stock when he accidently reved it up to nearly 10,000! No damage what so ever. I wouldn't reccomend it on a regular basis but your EVO should be strong enough to handle it now & then (when accidents happen)

 

Last year I was coming home one night in my old 2001 Celica GTS. (redlines at 7800, revlimiter at 8300)
I took off in first onto a divided highway and took it to 8k, tried to do a slip-shift into 2nd, but I was kinda liquored, and didn't get it into gear, but I still slammed on the gas. I looked down, and seen the tachometer sitting on the little peg just past like 9500rpms. Not sure how high I got, but it was pegged for a bit!!

Drove home fine, CEL came on the next day. The diagnoses was 'overrevving' and was a one time coverage under warranty. I sold it off!

 

I also had this happen in my 91' Talon when it had about 140,000 miles. I was going from 3rd to 4th and hit 2nd by accident, it buried the tach at 9000, not sure how high it actually went but that was high enough. I was at 6500 when I shifted out of 3rd. The car now has about 182,000 miles and gets beat daily by my younger brother and still runs great. The 4G63 is an awesome motor, a long as you keep up on the timing belt, lol.

 

Pretty lucky man, that would be tough to explain to the dealer.

 

I'm waiting for all the new threads titled "hey I overrevved too, no problems!" and "who can overrev the furthest? I got 9800rpms!".

 

WOW, thats all i have to say, ill just take your advice on how it sounded when you did it and not try it myself . Ive had to rebuild a few engines due to over revving. The cause for all three of them was rod bearings. Granted this was a v 8 so there not supposed to rev that high but anyways. The one i did was my own personal truck that a let a person test drive when i was selling it and thought he'd be fine driving it alone, gave me his license and stuff. Took off and about a block down the road put it to the wood and held it for as long as i could hear the truck. The guy didnt buy it and a week later it started to knock. I hope yours is okay, it should be the Evo's internals should be strong enough for accidents like that.

 

Heard the valves today on my evo with the trick mentioned and they all click...maybe im not positionong the tube correctly?

Granted I never over reved the motor but just wondering about this method...

 

They will all click, as this is a normal sound. However, if a valve has been damaged, it will be a different, far more pronounced "tick". In other words, it will be audibly different from the others. Since you do not have a problem, all will appear to click.

 

dang that hella crazy. that is hella high.
