PWR radiator caps

[SierraSVXer]

Of those who have the PWR radiator. I am having problems with the OEM cap and the PWR furnished cap leaking. The radiator has been lowered so the cap does not hit the hood. The rubber seals look good as well as the spring pressure and the overfill hose is tight. All the welds appear fine as well. Any others having this problem or switching to a name new cap. Any One?
