broken inner valve spring
Is there any way to tell without taking the spring off? It seemed to start ticking on the drivers side after I hit 6k the other day. I looked but can't see anything. Are the inner springs prone to breaking more than the outer? They are Patriot Golds

All I have ever seen personally is cracked ones. And you can usually turn the motor over and watch and listen and pinpoint which one then use a flashlight and find it. First thing is to pull valvecovers just to see what the hell is going on. Usually I see outers break theyre more susceptible to coil bind and are much tighter.

I have the Comp 921's with my cam and they tick as well. Unless it is a significant tick i dont think its anything to worry about. Cam only or heads/cam cars typically sound like sewing machines because they tick. I believe they tick because their is increased spring pressure when hitting the retainers. Maybe others can chime in?

I posted over on LS1Tech, you seem to be having a lot of valve train issues. Is the one that is ticking in the same place that the 918 previously broke? I am wondering if you have an oil starvation issues possibly due to some dirt or something sitting on top of the lifter.

It's my wifes car and she is getting pissed.
I did find out that my pushrods are too short so I bought a set the correct length. I HOPE!! that will fix it. If not I'm going to pull the heads and take a look at the cam. If the cam is fine I already have a new set of lifters that I will put in. I really can't imagine that the cam is bad. I bet I only have the max of 1500 miles since the swap. I guess I am getting things figured out though. I did find out that the original 918 springs were defective. And I did find out the base circle of my cam so I know that I do need the 7.425 pushrods. If I can't seem to get it fixed you wouldn't know of a big cliff around do ya?
