Pinging? Knocking? Clicking? how do you identify..
How do you identify detonation knock from a 258?
I have a rythmic knock noise from the engine. It is the most noticable at idle and does not go away when I retard (move closer to 0 tdc) the timing. I also have a small crack in the exhaust manifold if that is helpful. Other than the knocking the engine runs and responds great.
So how do I properly Identify the noise and determine if it is something harmful?
I've got too much month at the end of my money!
