Ok I was driving tonight and another turbo'd car pulls up next to me, so we were screwing around and I misshifted going about 65 I went from 5th to 2nd and there was some sort loud boom that came from my car so we pulled off in a lot and checked it out. Nothing seemed to be wrong. So I left and meet up with a friend and while I was in my car waiting for him the check engine light came on and it started idleing real funny any ideas? It still boost so I don't think its any hoses or anything like that. Maybe I bent the valves?!

 

yeah

 

u went from 5th to 2nd? OUCH.

 

loud boom+
5th to 2nd
--------------
engine is jacked


its simple math really

 

immortal, u forgot to add boost into the equation....equals bent valves and engine jacked

 

Check your cam timing first. The others may be right, but don't give up hope yet. When you accelerate the engine like that, the chance of skipping a tooth or ? is very possible. You will probably find that the the cam(s) are retarded.

 

Do a compression test real quick and see what you come out with.

 

I've done that before, turned out ok though

 

Yes!!, do a compression test. But realize that low numbers from a static comp test *can* be due to cam timing problems. Don't buy an engine until you check the cam timing.

 

65mph? thats just taking 2nd gear a few mph past redline... its not as bad as doing 80+ and downing to 2nd gear. i think i saw some pics of a guy w/ a rsx type s who did that.

 

how could u manage to downshifted from 5th to 2nd ??
i tried it on a motorway , but it didnt wanna go to 2nd ........
only could go into 3rd ....

 

(I'm still learning) how do you bend a valve? reving too high?

 

do a compression test, if that turns out ok do a vavle adjustment, ur prolly ok..

 

good call. I've gone from 5th to 2nd doing about 50-55...it's called down-shifting...makes the car accelerate... 65 probably didn't even bring the engine to 8000...so, it's probably not that bad, though the CEL is a scarey thing

 

the best one I have heard is some kid in a type r doing the same thing but much higher in 5th, like 90mph, any way he said, yeah i downshifted wrong but still it has a rev limiter at 8500rom....hehehehhehehheheh, bought the motor off him for 500 and repaired for 800 sold for a lot with clean title.

 

Check your plugs, you could have blown off the tip. Its the engine backfiring in the combustion chamber. Its either that or you blew your headgasket.

 

bastard... just kidding, good take friday

 

Well $1300 later its all fixed.
The valves were totally screwed. Place I took it to said they were the worst they had seen.
But I got
-Skunk2 low compression valves
-Crower retainers and springs
-ARP head studs
-New head gasket

P.S. be carful when you shift

 

sorry to heard that. But how do you shift from 5th to 2nd? Not trying to dis you or anything. How long have you drive a stick?

 

probably trying to go into 4th and hit 2nd by accident.

 

Yes, I was going into fourth.
I was in second for mabye a sec. But bye the time I got back to fourth I was too late.

All three of my cars have been stick. So about 5 years.

 

Ouch that hurts... I have almost done that before, I caught myself though.

 

at least it gave you an excuse to upgrade to really cool parts.

 

ah, don't feel bad man, i had a big block nova w/a rachet shifter, you know the kind that doesn't let you go in reverse...driving to work early one morning, tired as hell, hit the shifter, kinda wet out, kicked her sideways... bang it into 3rd, then for some damn reason i pulled up on the shifter and stuck it in reverse, luckily it was wet out. it just locked right up.... no damage though hehe everyone does dumbass stuff

 

just the other day i was doing a 3 point u-turn in front of two cute girls walking their dog... i was still moving when i dropped the stick into reverse.... CRRRUNNNCHHHH!!! i wanted their attention.. but not like that...
