Lighten up Francis.
Random question: Why is it okay to run the engine to break in the cam with just the outer spring if you are supposed to have both springs to run it under normal operation? Does it have to do with just running it for a short time with no real load or limited RPM?
Cool, thanks. I almost know enough to be dangerous![]()
open spring pressure ?? Lift? What was your lash set at for break in? *No zinc?? The reason I ask is because*I'm curious at what point this cam wipe out is happening? Did you know it was gone right away? Or did it take a little time before you noticed? All 3 times conditions were identical besides the inner springs ? *disclosure * TAKE THE INNER SPRINGS OUT ! ! !(I lost 2 cams before I found out about the Zink in oil????) and when I got my 3rd cam and had to totally go through my engine again, I read in the instructions for my ISKY Vodoo to remove the inner springs during break in. YOU BET YOUR *** I DID !

Try and get it to fire up as fast as possible ! Triple check everything ! Get it above 2000 rpm's asap! Very rpm's up to 3000 and back down for 20 minutes. *avoid the temptations to "rap-rap" on the throttle !!* til you get the springs back in.Thanks for the input everyone. I pulled the inner springs and will be running Joe Gibbs Break in oil at startup. Hopefully it goes smoothly. :burnout:
Open spring pressure what was it? Zinc in oil for break in ?

*disclosure* TAKE THE INNER SPRINGS OUT !! with that said there's probably a half a dozen arguments not to also. let me give you a scenario- you do all the right things including taking the inner springs out, have plenty of cam lube, correct brake in oil, and then you go to fire it up. you're pumping the gas turning the timing to get it right not wanting to crank it too much, pump it a few more times. try it again and she comes to life, but a little too hard because of all the gas pumping and open throttle and she shoots up to six grand real quick for just one second(remember all those light expensive high compression parts you just put in that motor?) and fling ping a retainer from one of those light springs on that big cam lobe flies off! catastrophic failure! anything could happen! bad luck sucks. it's crazy the things you read when you read the Internet for both arguments just like you're reading the internet right now.
