Just to be certain im thinking of the same thing, the heat riser is on the bottom side of the exhaust manifold and it has a plate inside that either opens to allow heat up to the bottom of the intake manifold or 'closes' directing heat away. Is this what you refer to as a valve? If so the counterweight is not stuck, I can move it with the engine hot or cold I just have to oppose the little heat spring. However I have not seen it get hot enough to release the heat spring letting the weight fall down (closing the plate). I have only seen the weight up so it should be open. |
