if anyone was or wasn't following my other thread https://ls1tech.com/forums/generation-iii-internal-engine/207260-help-down-7mph-3-4tenths.html I found the source of the problem. there are about 5 springs that are 'broke' like these pics show. they had less than 2k miles on them and probably around 75 passes at the track. anyone ever seen springs fail like this???

what would cause your springs to break at the tips like that? thats all sorts of f#cked up. thats not an fouled installation, so its got to be some sort of failure in the manufacturing process. have u talked to comp yet?

no, I haven't. do you think it would do any good?

well if you installed this springs exactly to spec(as i'm presuming you did), and you were using them in a fashion which was within their design threasholds, and they just up and quit on you, and then **** all over your motor, then there is definitely something wrong. especially if you don't have a ton of miles on these. are there any special circumstances? high miles? lots of high rpm's?

i believe 383ss told me he had about 1000 miles and 75 passes at the track. sorry to hear john, good that you caught it before a real catestrophic loss.

Looks like maybe valve float? I had some retainers once that the bottom of them were beat to hell from float. Good think they didn't break in the middle though and drop a valve!

yep, gator is right. about 1000 miles and probably 75 passes.

my limiter is at 6800 rpms, but I usually shift at 6500ish. the lift on the cam was 602 and the springs are supposed to be good to 620 I think. they were installed by the head porter, so they should have been done right.

It doesn't look like that's correct retainer for that spring. It being smaller than the O.D. of the spring is causing undue stress on the tip, causing it to break. The correct retainer is .007" larger that the O.D. of the spring.

damn, i didn't know that I didn't install the springs, just ordered the parts I was told to by the head porter and he did them. I will have to bring this up with him.

thanks for the info.

Piqued my curiosity. Comp doesn't know it either. If you don't mention this to the porter, I will. Look at the picture of the 776 retainer...the area available for spring seating would not be .007 larger than ANY spring....

776 retainer for 1.43 spring

985 is a 1.43 spring....

Brian, I see you work at Comp. I don't want this to turn into a flame fest, do you have any insight into what is going on?? Is this an error in the catalog parts called out, or??? Is the desired retainer dimension actually .007 larger than the CENTERLINE OD of the spring or the OVERALL OD.???

thanks for any help. Just curious on my friend's (the porter's) behalf.

lol....well the retainer that is actually recommended for that spring is a larger retainer, but I do now see where you are comming from on the LS-1 retainer your looking at. That actual retainer is only a 1.300" O.D., I wouldn't use it in this situation. The only thing I could say is that the spring isn't staying located properly and allowing it walk enough to put undue stress on that little spring tip..btw you have a pm
