after changing my plugs,wires, and injectors, i finally decided to pull my valve covers to see if i broke a valve spring...and what do you know the second to last one on the driver side is shattered.... dual spring..... my question is am i going to have to change all the springs.... or could i get away with just changine that one broken spring??? since the rest of them are used and broken in will that new spring disrupt anything.... let me know what you guys think.... thanks

 

I think you should test the other springs and reuse them if within spec on seat presure. Unless they are already high mileage (over 15,000 miles,) then of course just replace them all while you are in there. If you replace them, just put in Comp 918's; you don't need duals with that cam.

 

How many miles were on the springs?

 

i say about 10 k around are on the springs.... the cam is a 225/225 .595/.595 114 cam....

 

What brand spring?

 

My single 918's is still going on 15,000 miles on a .600 lift cam.
