Bought over revved LS1...What Next???

**txbeaux** · 10-22-2006, 06:36 PM

I just bought a 1999 complete LS1 that has been over revved. It had several bent pushrods and a scored lifter bore. My concern is the lifter bore. Is this a major deal or a simple fix? I'm an hour east of Dallas. Anyone know the fix or a good machinist in the area?

I've heard of people just replacing their bent pushrods and after runs good as new, but i don't know about the scored lifter bore.

I actually reved my car last week give it a good rev, now this story is making me feel bad for reving my engine. I don't think i hurt anything, at least i hope not. But, just reading about your situation makes me not want to ever rev my car again.

What year is it, im sure you got a good deal on it, fix it up and burn rubber.

The LSx engine can handle the revs with ease, bent push rods and the like come from mechanicaly over revving by missing a shift and dumping into 2nd instead of 4th. Don't worry about running the LSx at high RPMs, it can take it.

I had the oppurtunity today to talk to the person that actually over revved the LS1. Missed shift....Anyway, he said during his thrill he squashed the roller arms on a lifter and while trying to remove it, he gouged the wall of the bore. Soooooo....... does anyone know if this is anything? Can I just clean it up with a brake cylinder hone and go or is there more to it?

ok i know this is stupid

..but i've always wondered how does reving in Neutral hurt engines..since at times the engine goes that high durring driving..so whats the diff between N revving and driving reving?

LOAD

**shady milkman** · 10-24-2006, 04:39 PM

man i keep on sounding dumber and dumber but i'm not to knowledgable about the internals..what is load?

**txbeaux** · 10-24-2006, 05:00 PM

Tires on the ground....moving mass...not freewheeling....
So do you know how to fix my engine if it needs fixing?

really sweet..becuase everyone used to want to hear the LM exhuast on my old T/a..and now they want to hear the custom exhuast on my G/a...and when i rev it they always say i'm going to make the engine explode..

Well I hope you are not reving it to limiter.

**shady milkman** · 10-24-2006, 05:15 PM

hellz no 3,000 for the g/a and used to go around 4000 ...but again if i were to go and hit the limiter all the time..i take it that it would be stressfull on the engine becuase of the load? sorta like being in 1rst gear on a bike and going down a hill pedaling as fast as i can..same logic? sorry for all the questions but internals are by far my weakest subject

Not because of load, but because the limiter cuts fuel which will make you run lean.

ok i understand now thanks ed i knew i could count on you...hows the new engine work going? did you ever find out what it was..a land ring in #7 i think is what i herd?

**txbeaux** · 10-24-2006, 05:23 PM

If you guys want to throw it in neutral and rev it till it blows...go for it. So back to the question at hand. Does a gouged up lifter bore make a rats a$$ or not?????

**shady milkman** · 10-24-2006, 05:29 PM

geez.. um if its gouged you can lose oil pressure in the lifter and it can cause float or rotation i believe

. i'd sugguest fixing it as soon as possible

Hey, no need for that. He's just frustrated because he asked a question on a problem and hasn't gotten a direct answer to that question. He knows he needs to fix it, but how much nd difficult.

Personally, I don't know, sorry. If the lifter bore needs to be machined, that's a lot of work I think. Removal of a lot of crap just to get to it.

**txbeaux** · 10-24-2006, 06:04 PM

One jackass to another....I just asked a simple question...looking for a simple answer...Not all this crap that sounds like its coming from bunch of 16 year olds. Either you know something about gouged up lifter bores and fixing them or not.
