Knock
|
Today on the way to work I was doing some scanning on the expressway. The gauge recorded a few degrees of knock when going wot in third, no more than 1.3 degrees. Also when cruising at 65 in 5th gear I got quite a lot of knock when I would go wot. It hit as high as 3.5 around 3000-3500 rpm.
I have never got knock like this before even after the pulley install. I have an exhaust leak so I'm wondering if it is possible for it to cause the knock?
