I just removes them from the engine and they looked old and had white corrosion on them , dropped them in a pan on the stove and watched them open with a thermometer, they didn't open evenly, one was noticeably slower than the other, they started to open at 120 F and was fully open at 130 F. Closing one was smooth and the other just before shutting it snapped closed you could hear it. I 'll install them in the morning, what kind of sealer, Permatex #2 or silicone?
Water telltale is peeing out about 3 feet behind the engine, I don't think it's a water pump issue.
