Valve lash adjustment bob 9-14-02  
I just had a valve lash adjustment done on my 300 cat. The cost was 410 bucks, and wonder if it was really necessary. I have approx. 22000 miles on it...

just wondered if this was money thrown away or is it really necessary.

I have heard of people going without ever having it done, and no problems.

In my experience with working on diesel engines, I would say that most or the times that all things wear fairly evenly in an engine valve train. That is that with use that all things wear including the valves and seats, so the valve lash remains even throught the life of the engine. I have checked valve lash on Cat engines, 3406 for example with over 500,000 miles and found the valve settings to be very close to the recommended gap.
That is not to say yours didn't need to be set, just that I don't feel it is always necessary to disturb a good running engine unless you have a problem.
