Message So my car is getting a scrapping noise from the engine area. I was under the car revving it up and upon decel there'd be a scrapping noise under the drivers area. I've tested the compression and they all came out above 150 psi. Interestingly enough, my car can't boost anywhere near full boost. The scrapping sounds like a piece of metal on one of those old stone cutting wheels.
