I'm thinking that if the spring isn't properly seated it won't be able to spin

 

It's also true that if you damage the finish of the spring, it will weaken and fail. Spring compressors that have jaws or claws can easily damage the surface of the spring. I used this type of compressor on the rearmost springs when I did my springs the first time, and although the spring was OK, the jaws somehow found their way to the valvestem and put big nicks in it...(luckily it's still OK 23k later)

 

With his size of camshaft, even if you could *possibly* get a spring unseated (in the 300+ LS cam installs Ive done ive never had it happpen one time, not even accidentally where I put the spring on and noticed it unseated then fixed it. Its just never happened. 300 * 16 = 4800+ valvesprings ive changed. The spring was not installed wrong, period. Everything was fully inspected after installation before final assembly.

Well its hard to take anything into fact you read on here, everyone has a buddy who has had something happen that validates why you think it could be something... hearsay.

My kind of experience? Well Ive built more LS based setups engines than any one person I have ever met in person. Ive owned a LS based performance shop since 1999, since before any most every "LSx" performance shop that sponsors these sights were thought of, without the need to ever advertise for business since ive opened. I've done over 300+ cam installs on LS based vehicles, 200+ cylinder head upgrades, 100+ LS motor builds and full installations, dyno tuned 1100+ LS vehicles on the chassis dyno since the origins as a beta tester for LS1Edit before HPtuners/efilive existed for Gen III/IV vehicles. Ive been flown in from CA for race teams to the NASA and SCCA national championships to repair/build LS engines for American Iron Extreme and TTU race teams in Mid Ohio more than one year.

Oh wait.. we are taking knowledge on valvetrain/cylinderheads...sorry I got distracted. Call some people in the cylinder head industry and drop my name and see if its recognized to: Tony Mamo @ AirFlow Research, Brian Tooley @ Total Engine Airflow, Anyone @ Texas Speed, Andy @ A&A Corvette, George Lara etc etc...

Im sorry, who were you again?



Detective work from behind your desk 1000's of miles away? You should open a internet detective biz, damn you're good.

 

man why so defensive? I dont think bud has ever said one hateful thing... just his opinion and experience...

 

Well you've got the experience for sure, I'll give you that, and the failures that I've seen weren't on LS based engines, so maybe I'm a little off with that. I didn't have any problems doing my springs two separate times, but I know how easy it is for someone to make a mistake. Didn't realise that the LS based engines were so idiot proof...

As for being an internet detective, yes, if you put the pieces together, it sounds like the sping was installed incorrectly, simple as that.

It's good to hear that you've done so many LS based spring swaps without a problem, but are you the person who did this install? If so, I'll call it a bad spring given your track record.

Me, I'm nobody, but my father is Bill Ceralli (same name as me), he builds race engines that currently hold over 40 National Records. He's been in buisiness since 1971, and I grew up working in his shop.

You seem like an excellent salesman BTW, Trader Rating=55, I'm surprised that you posted somewhere besides the Classifieds. Why don't you become a sponsor here given your experience and charm?

 

Yes he is who installed My cam. And has done all the installs on my truck.

 

Well that explains the defensiveness.

 

So what I'm getting from all this is, "PAC makes a defective spring and you will have a chance of them breaking on you if you run their product." If this was a bad batch of springs your likely to have another one fail so why would you replace only one? Why wouldn't you work with PAC or SDPC and send them all back to be tested? This way you can get a fresh batch and not have to worry. I'm sure PAC being such a major player in the speed industry would want to bring the springs in to test and fix any defects that might have slipped by QC. This is how it normally works. Why would you want to roll around with a set of 15 other springs that could break and cause even more damage?

I think their is more to this story than what is being posted and unfortunate because this is going to probably turn into another rumor that PAC makes springs that break. Derek why would you come on a forum and ask people what springs you should run when it sounds like you have all the answers with your tuner/installer who has installed over 4800 springs? Sounds like you don't have 100% trust in him in the first place... On another note, Socalspd, I don't care who you are, or what your history is, you sound like the typical ignorant know-it-all car enthusiast. I can't believe you actually represent a business with that highly unprofessional post towards Budhayes. If I were anyone on here, I'd never want you to come close or have anything to do with you or your services. You sound like a disaster waiting to happen.

 

I only got upset because of the "ignorant statements" part of your last reply. I did fully inspect the springs and timing chain installation before it was reassembled. We have a routine that adds a couple minutes to our labor but prevents mistakes. We always have a 2nd person fully inspect installations regardless of the installer. I have one of my employees inspect anything I do as well, everyone no matter how experienced can have a mistake and we go above and beyond to prevent that. We fully heat cycle the springs a few times with cool downs as well, which was done on Derek's truck.

Becoming a sponsor = lots and lots of phone calls per day from non-local customers when I can't keep up with the workload I have and I already get too many phone calls.

You're never going to please or convince everyone..This is my last post regarding it as i've went out of my way to fully explain how things work and what has happened...theres always going to your nay'sayers etcetc that will give their own thoughts or opinions. To each their own

 

No one ever said anything about me only replacing 1 spring, i am replacing all of them. And i never said if you run PACs you have a chance of them breaking. I would run them again if i didnt have to wait for them to reply and ship me a new set, If they would even ship me a new set. I contacted SDPC and they will only Send 1 spring and not a new set. I Contacted PAC 3 days ago with no response. Kinda hard to have them tested if they dont reply. And why i came on here and asked about springs? Because i wanted to here everyone elses thoughts, I pretty much knew which springs i wanted to run, just wanted to here what everyone else thought. I didnt know you couldnt ask questions on this forum, isnt that the purpose of this place? Advice, thoughts and opinions? or am i wrong.

Some of you guys are bein so defensive for PAC, Like they cant have issues just like installers can have issues. There is always a first for everything, And i would be happy to have them tested if they just reply to me. I still like PAC, have nothing against them and if i had time to order new springs and didnt need my truck running right away then i would get PACs again. **** happens. All part of modding..Now can we move on to something more important. sheesh haha
