Broken Comp 921 valve spring
Broken Comp 921 valve spring Was looking forward to finally getting some track time with my car last weekend. In preperation, I started an oil change and noticed mangled metal fragments on my drain plug. I was cleaning them up when I heard a "thunk" in the pan.
I fished around in the pan and pulled out what looked to be part of a valve spring. I pulled off a valve cover and notice the inner coil on one of the valves was half missing. I found another large piece of this spring back by oil drain.
This sucks, but it doesn't look like anything else was damaged. I will have to check the pushrods, but I think those will be OK. Obviously, I need new springs.
I don't have the tool I need to get at the backs, and am not willing to spend $130.00 on one, so I might have someone else do it.
I'm also scratching my head why Comp 921s (which seem prone to breaking) are twice the price of everyone elses springs, even the new Comp 926s which are a stronger spring.
My cam is pretty mild by the standards of what is available now, so 921s are overkill, I would like to stick with a dual coil, any recommendations? Patriots or anything?
Mods are in my sig..
