Possibly but probably not. A lot of the times springs will get fuss points in them if they're setup at a wierd installed height(to close to coil bind, or to far away) but i'm not sure if it would cause one to break. I mean it's possible but i can't say for sure.

 

Not worried yet. This is the first I heard of them breaking. I plan on running mine

 

eric you have to understand there are many more people using the same set up with no problems at all, there is no pattern at all

 

Were they heat cycled properly when new? Does the engine get warmed up to temp before getting beat on? Those two things can kill springs.

 

Maybe it's just a bad batch of springs or something.

 

"Were they heat cycled properly when new?"

When I installed my new Manley beehive springs they spelled out a break in procedure. Basically you had to bring the motor up to operating temperature and not to go over 2500rpm. Then let the motor cool off completely. I followed the procedure and then some. No problems as of yet and have spun the motor to 6500rpm's.

 

What is the best way to heat cycle the springs?

 

Can we get a batch number on the PAC1218, mine are sitting in the box on the shelf across the room.

 

Straight from Comp Cams website

Breaking In a Spring
1. It is important for new springs to take a heat-set. Never abuse or run the engine at high rpm when the springs are new. Upon initial start-up, limit rpm to 1500 to 2000 until the temperature has reached operating levels. Shut off the engine and allow the springs to cool to room temperature. This usually will eliminate early breakage and prolong spring life. After the spring has been “broken-in”, it is common for it to lose a slight amount of pressure. Once this initial pressure loss occurs, the spring pressure should remain constant unless the engine is abused and the spring becomes overstressed. Then the springs must either be replaced or shimmed to the correct pressure.

 

I don't think this guy has the high lift version??

 

Me and the other 2 guys does not have the same lobes, lift, duration etc.

 

Nope, actually I have about ~.030 less.

 

I dont think you have to be worried, it´s alot of people running the LE2 heads/cam with the 1218 springs..

 

And yes I did heat cycle them to operating temperature atleast 3-4 times before I even took the first road test.

I will try to get my batch reference number later today..

 

All i'm saying is yours broke and then 2 other guys with the exact same springs have float problems. So maybe it's just a bad batch or something...
