Since this is my first diesel I have to ask if a part of preventative maintenance should include replacing the glow plugs periodically? Is this something people have typically done on previous powerstrokes to avoid a tip breaking off and trashing the engine? I currently have 93k on mine and am wondering if I should just go ahead and put in a new set. My only concern is having a tip break off during the removal/install due to carbon build-up and then having the take off the head to get it out.
