Update on Valve noise 380SL
Well, upon further inspection from the purchase of the spring compressor. I found the real problem. Evidently oil was not getting to the cam and rockers on Cyl #3. As a result the cam has a flat spot on one lobe and a ridge on the other for the same cylinder. See Pic#1 The rockers are very worn also. Pic#2.
The plan is to replace the 2 rockers and leave the cam alone I checked a random rocker on a cylinder with no cam wear and it was perfect. I think I got to the oil tubes just in time, well almost. The engine was running perfectly even with the bad cylinder averaging just under 21 mpg tuned to European specs.
Will this cure the original valve noise problem?
Thanks
