The mating surfaces of my rocker arms on the exhaust side are badly pitted and from what I have read need to be replaced. Any thoughts from anyone? What about the inlet side - looks much better. Are these serviceable?
Do I need to replace all, or just the ones that are pitted?
Now the camshaft itself is another matter. There is discolouration on the pads, but only one small area of pitting; otherwise smooth and the bearing surfaces look OK also. I think maybe the pitting could be ignored as it is not in a central area?? Anyone got thought/advice on this?
The measurements of the cam height, however give me cause for concern:
1 2 3 4 Tolerance
Inlet 35.84 35.72 35.78 35.82 >35.86
Exhaust 35.40 35.38 35.36 35.40 >35.36
According to the shop manual, the exhaust measurements are within tolerance (just) but the inlet seem a little too low.
The manual also talks about measuring the base circle; where is that?
So can I get away with keeping the cam? Given that it is recommended that it is better if the parts wear in together, if I replace the cam, should I replace the arms as well? The adjusting screws I think also need to go.
Thanks
