Dear gpeters-- Why don't you believe your mechanic? If you don't trust him why not get a second opinion? If this were a doctor instead of a mechanic and the doctor said you needed surgery I think you might ask around first. But as to your problem. Camshafts usually last a long, long time and if they do go bad they generally reflect another problem in the valve train, like poor oil flow to the head, or incorrect adjustment of the rocker arm assembly. But do you have the symptoms of a bad camshaft, like loss in performance, difficulty in starting, or backfiring? Do you notice a dark, almost oily exhaust? How do the valves sound? After considering all this, the choice is yours for sure, but my choice would be a second opinion. Good luck from Bovan.
What is it doing? Don't throw parts at it unless you are sure.What are the symptoms,maybe I can help you.
