i was wondering if this is suppose to be done to a ds after its a year or two old. i know your suppose to on certain engines but dont know about the ds

 

the manual says once every hundred hours, or once a year, which ever comes first.

 

yeh

 

Crap! I've never done it so I guess it's time. I think I'll tell the wife that I need parts to do it correctly, like new cams and better valve springs so I won't have to do it again. And maybe even a "better piston" so the valves won't be lonely.....lol
