They can go in 1 start to sveral gallons depending on the tune of the engine. Can you show pics or be very descriptive of what they look like when they quit on you?

if you are running at really high rpm's, then your engine will be creating alot of heat... this combined with the vibrations can loosen, and seperate the coil in the plug.

Sounds like you're either running too lean/hot, or rich. You could also have crank bearings going to hell.

Glow plug
The glow plug still looks like it is new, except for the outer ring is black in colour and almost totally dry when removing the plug. There is no discolouring in the middle wire. Could this be happening because of the temperture. It is abit on the cold side in London. I am using a R3 plug (med. - from 3,5 to 6 c.c. thanks

this is what happened to my picco. My bearing retainers where coming apart and destroying my glow plugs, among other things. They must use cheap bearings from factory. I'm putting some ceramics from boca in it.

Break in is very hard on crank bearings, the best thing to do on a new engine is warm it up with a heat gun or at least a hair dryer. Prophecy, it sounds like you need to richen your high needle, especially if it's cold out. I don't know how cold you're talking but if it's about 30 degrees f out you should wrap the head in something to help hold in some heat and turn that needle out a full turn extra and then tune from there.
the best way to check a glow plug, with out passing a lot of current, is to get out your old VOM. and check the omhs of the coil. how ever do NOT grab the threads with pliers, it will damage the plug threads, then strip the threads in the head.
