Was stoked to replace the water pump and realize it wasn't the motor. Just a thought.
And a good thought.
My car has started an odd noise when cold. Sounds to me like a bad rod, or a rod running without oil. Once the water gets to about 180F, the engine sounds fine.
Yesterday, I put an oil pressure gauge on the car (which is how I messed my back up). The numbers I am seeing are consistent with the oil pressure numbers I saw on the two other Crossfires I've owned. So at least I know I don't need a new oil pump or oil pickup...
My next move:
Once my back heals,
1) I will start the car cold and observe the noise.
2) I will then shut the car off, take off the belt and restart the car.
3A) If the noise is still there, I know it is internal.
3B) If the noise is gone, I will put the belt back on and if the noise comes back, it's in a pulley or bearing outside the engine.
I suggest this as your next diagnostic step, Perry. Let us know what you find.
