i have a B16 thats making a very loud ticking sound. Sounds like really loud valves so I had a valve adjustment done but the sound was still there. Doing the valve adjustment for the second time, I noticed that some of my rockers were very loose. All valve adjustments were good so I determined the rockers to be my problem.

Well I remember hearing some where that if the rockers became too loose that oil can leak into the combustion chamber. Is this true??

Also how would i go about fixing this problem?? should i replace each loose rocker or who i be able to just replace the bushings for the rockers???
