An update.

I went ahead and had Pacific Power in Corborg adjust the valves. The coach has less than 65K miles but we decided it would be better to have Marathon take up the closet floor now, before we put everything in it, rather than have to unload everything later.

The tech doing the adjustment stated that half the valves were too tight and that seemed to be the trend from the factory. He recommends doing them every 50 to 60 thousand miles but of course he wants the work.

He found a loose connection on the Jake brake wire inside the valve cover which he repaired and the fan bearing about to go as well so Marathon is changing that.

Looking forward to taking possession next week.
