I puruchased a used set of the Texas Speed .660 dual valve spring kit with titanium retainers. Previous owner claimed 5000 miles of use.

I have a habit of inspecting everything before installation (even new parts) and found one valve spring had the inner spring moving in and out easily, literally slid. In comparison all the others were quite hard to move within the outer spring.

Anyone seen this before?

Hope a Texas Speed rep on here can reply.

He will probably tell you to never buy used valve springs again.

Yeah, don't skimp on stuff like that, low miles or not. Hopefully you didn't pay too much and it's a cheap lesson learned.

I would rather get an answer directly from Texas Speed or some real input from experienced members.

If they advise to replace that spring I will, I believe they use the PAC 1905 and its only $8.

I agree, you shouldn't cheap out on important items, espically valve springs, you should never buy used valve springs, as there so cheap, theres really no reason to buy a used set

Don't use that spring is the realest input you are gonna get.

Have the springs pressure tested. Replace the ones that fail.

I think I spoke with you earlier this week about this. The inner springs are able to come in and out of the outer spring. If for some reason this spring is different from the other inner springs you have you should not use it.

Our replacement is not the 1905, we have a specific PAC spring to fit our retainer you would want to get directly from us.

Hi Jon,

Yes we spoke but I had posted this up before our phone conversation.

Don't disagree that the springs are supposed to be able to come in and out, but how easily should they be able to move within the outer spring is what I keep wondering.

The inner spring literally slides out of the outer spring, the others are an interference fit and are almost impossible to push out, making that 1 spring the odd one out. Dimension wise it is equal to the rest of the springs.

How would I be able to get a replacement spring from you?

FWIW - LS engines are interference engines and a failed spring can result in serious damage to pistons, valves, connecting rods and other parts. Weigh the cost of a spring compared to the other parts.
