a knock question

Post by euroshark »

well, im bored and have time on my hands, figured i would ask this question.

so, my 22t makes a knock noise that is starting to get annoying. it occurs cold and warm and between 2000-3500 rpms at only 1/8-1/4 throttle input under load. i have researched and found that it could be a rod bearing, piston slap, or a bad crank pulley. it is bad enough that i can feel it in the floor boards. i am not new to the subie scene at all. this ss is my 4th ss and my 10th subie. i have never heard this noise in any of my subies so this is new to me. i have a brand new grimspeed crank pulley that i have not installed yet so i can not eliminate that possibility yet. any input from fellow 22t enthusiasts would be greatly appreciated.

Can you elaborate on the "knock" sound. Is it an engine sound or some other kind of knocking sound?
