Over revvved

[unibuga]

so i was accelerating hard i was close to the redline and it kicked out of gear and stalled it starts and runs fine but has a loud tap from inside the motor that my dad said sounds like a rocker but not sure

any ideas on the problem?
ive heard you can bend a push rod really easy on these cars

i read alot about bent pushrods when going redline....i read alot about lifters too.. but i just read.. prob a good place to start tho

yeah when it over reved it went to like 9000 then died but it runs fine other than it has a tap and when im close to redline it feels like its lacking power

9? i take it your moded pretty good? i dunno another thing common is piston slap ... but i dunno how likely that is if you didnt hear it before....

i remember i redlined my iroc z really haard and blew the manifold gaskit.. sounded like a ticking noise but it was the exhuast manifold...

post a sound clip video and im sure others will chyme in

[unibuga]

acctually im basicly stock other than cat back and lid ...i dont why the rev limiter never kicked in but my tach needle went past the little peg and into my speedometer

Check pushrods

[unibuga]

is it hard to do?

[silverWS6]

Na, do you have basic mechanical skills? Remove coils, which on your car I think you have to do one by one. Then remove valve cover and then remove each rocker one by one and pull out the pushrod. Just roll it over a piece of glass and see if it's straight. It's probably on LS1howto.com

[unibuga]

yeah im pretty mecanical sounds easy enough lol i may do that tomorrow

[silverWS6]

Good luck

9k? wow! I bet that sounded ungodly

[unibuga]

of course my tach doesnt go that high so i estimated the rpm it was screaming lol

Another vote for a bent pushrod. I did this when I thought I could outshift the computer in the 02...

FWIW, my best time in my sig was with the PCM controling the shifts...

[unibuga]

any ideas for performance ones?

I'll have to check with my mechanic but I believe we went with Comp Cams pushrods. They have a thicker wall??? I dont remember. It was 4 years ago...

He also suggested I let the PCM do the shifting...

[unibuga]

yeah maybe some one will come in on this convo

So, you let the PCM shift for you. Wondered why, now I know! I'm sure the shift is set a bit higher than stock.

To OP, check with KY speed, a sponser, for pushrods. Sure sounds like a classice push rod bend. Hope nothing else got hurt, if you really did rev it that high. Mayber somebody removed the rev limiter on your car....dumb thing to do unless your engine is built for it.
