Can stock L61 valvetrain handle ~10,000 rpms?

Answer: NO

Story: Doing things that are only legal in Mexico, I was shifting very "hard" through first, second and third and the car was feeling great. When I went to go shift from 3rd to 4th I released the clutch a little too soon and wasn't able to get the car into forth so I hurried and pressed the clutch in again to get it into gear...when doing so I slammed it into 2nd. I KNOW IM A BAD DRIVER, so as I put the car in what I thought was 4th gear I slammed back on the gas.......I've never seen a stock tach move so fast in my life, BOOM! clank clank clank.....shot on of the lifter on the exhaust side out of place and ended up with only 3 rollers still in place on the exhaust side when all was said and done.

Had Skunk with me at the time and we went to go get the tools to see if I slammed a plug closed and upon taking all of my spark plugs out all were still open. Took the valve cover off to see that the clank clank clank was my rollers pinging our under my valve cover. Get the car towed home and let it sit for the day.

Skunk made the 2 hour drive BACK to my house this morning with spare valvetrain parts in hand ready and willing to replace all that needed to be replaced to get the car back on the road and running the way it did before I pulled my stunt. Started on the car around 9 and hand everything back together and running by 2pm....and that includes me breaking off one of the valve cover bolts in the head. I just wanna thank Skunk HUGE for doing what he did for me today and his willingness to help with whatever i needed help for. Thanks a lot man I could NOT have done this without you. Also a thanks to Jenna for her help with the whole situation also, thanks a lot guys could not have done it without you.


Point:: Hit your gears and dont take stock valvetrain to what I think may have been 10k because the rev limiter said "F YOU" and let the motor go.

Damn you for getting it towed back to the house. It would have been way cooler to put 8 new lifters, 8 new rollers, exhaust cam, and re-time the motor on the side of the road. Anytime man. What the hell are friends for if you can't use them and abuse them, make them work in the 98* weather all day then just ship them back to Rockford...lol jk.

Lucky having people that live near you that are bonified professionals when it comes to working on a J, wish i knew people that lived near me that were professionals like you two. As for the part about never seeing a stock tach move so fast in all your life i know what you mean, i don;t have the 5 speed i have the 4 speed auto but one time i was at a light, and i happened to look at the tach and it was just a little past the 1 next thing i know i look up and the tach is like 5400 i'm like dang and i didn't even notice the engine speed up either i thought i was just doing the flow of traffic. It finally dropped back with a little bit of a Jump similar to the way the engine sometimes jumps when i shut the car off, only jumps when it's real warm though almost like it's gonna diesel but it doesn't

ohhhhhh curt's 'rev limiter' tuning?

his sounds damn nice at 8000, i wonder what yours sounded like at 10,000 hahaha





Re: Can stock L61 valvetrain handle ~10,000 rpms?
Tuesday, September 02, 2008 8:38 PM
well it sure as hell wasnt his tune...it was my lack of ability to shift the car from third to fourth and instead shifting from third to second at 90mph.....im guessing on 10k....wish it could rev. that high.



Re: Can stock L61 valvetrain handle ~10,000 rpms?
Tuesday, September 02, 2008 9:23 PM
good to see you got it back together so quick man

make sure you hit that 4th gear next time I know its a bitch.. I used to miss it all the time until I just raised the limited and held the @!#$ outta 3rd instead

yeah i know, i was just giving sh!t....

thing is though... should'nt the rev limiter have caught? why didnt it?



Re: Can stock L61 valvetrain handle ~10,000 rpms?

The rev limiter didn't catch because it was the most violent downshift you can imagine. The rev limiter will prevent you from going past it on acceleration, but if you go from 3rd to 2nd at 90ish mph the engine is still gonna rev to the moon. I've missed the 3rd to 4th shift once too, anthony got off easy w/ it being a lifter, I destroyed a clutch when I did it.

Few more things to add

McLovin wrote:Is it timed already? *Skunk nods* I hate you.


Just a few of the texts and pieces of conversation from yesterday that I found funny and entertaining.

One more thing. I think that the motor in the car needs to see boost ant. I'm really confident in it now. A compression test to verify that it is ok and I say we do it to it. Start collecting piping dude.

VERY NICE! GREAT SUCCESS!

Nope, but he is at my beck and call until I say he's payed me back . O anthony, could you come change my oil...hey any, my tires need to be rotated...bitch get that @!#$ trans out will ya...i don't feel like pulling that turbo off, get on it. just a few of the things I COULD do to him...but I won't, I only need a hand w/ the trans and he can consider the favor returned.

Easy there killer, his limiter is set to 7200. Soon as my car is back on the road I'm gonna run 2nd up as far as I can and see what the mph is at 8k, then we should be able to guesstimate about what r's you took it too. I'm thinking it slowed down just a bit so maybe like 85ish mph and then the lifter said "Fukc You!" One more thing to add though. For 124,000 miles, that thing looks great under the vc and in the timing area.

Yeah it was awesome of him to do that for me.

Skunk: if the compression test checks out ill consider boosting it....a little afraid to now.

And that had to be one of the loneliest cops in the world ot pull me over on the highway when no other cars were near me for my exhaust.

This is what we do. Compression ok, install turbo, you go inside let me have my way w/ your car for an hour or so, then I hand you the keys. If it can hold up to an hour of MY abuse, there isn't anything you could do to it to break it lol.

I did the same thing a long time ago. I let the car go getting on the highway, top of third I went to hammer 4th, it didn't go, so I rev'd it and slammed it into 4th...or so I thought, it was actually 2nd. I almost flew through the windshield, I took a peak at my tach and it was about 2 inches past 7000. The tires chirped, massive puff of clutch smoke and I checked my rearview mirror for parts of my drivetrain lying all over the road....but there was nothing. As far as I could tell, there was nothing wrong with the car and this was before the car was boosted at least 50k km ago.
