well the problem cylinder on this motor was #4 which was the one that the ring lands broke on.... I know thats the common cylinder for that to happen, meth or not, but you could also see that the two rear cylinders were leaner then the front two. the valves and combustion chamber showed it. It might not have been knocking but it was def leaner the the front two....

Also monitoring knock is a good thing, but it is not the end all be all. You need to evaluate plugs as well. The spark plug is the only thing we have that we can look at to tell us the what is going on in the cylinder. Also motors make alot of noise up in the higher RPM,s and knock sensor sensitivity is effected greatly. alot of big power cars cant even use a knock sensor due to all the noise.....


Let me know what the "Pros" say....
