    Glow plugs

    Anyone have any problems with glow plugs? Mine is tuned perfect runs great but when i am done for the day and do my after run maitinance the glow plug looks like the coil is being pulled out. Anyone have this problem? I have my tuning down for sure i have two t-maxx's a 4910 and 4907 and i have never had this happen in those! Could it possibly be from high speed runs?

    Hmm. I dont really take my plug out, just shoot WD in the intake after each run. Cant help u there, but if it still runs fine i suppose it shouldnt be that bad.

    How old plug? could just be the compression/suction in the engine

    Brand new plug one fuel filler bottle ran through on new plug and it does seem to have more compression than my other 3.3s

    Glow plug damage is due to tune, internal engine damage or foreign matter inside.

    If all you are doing is high-speed runs then that could be your issue. These engines are not designed to run sustained high rpms for a considerable amount of time.

    I think that is the problem dg that is pretty much all i do is speed runs bc thats all the pavement i have room to do.

    Welcome to the forum. And yes, that or my 4 stroke nitro... Except it has no compression and I can't find the wrench to get it off the plane

    alot of time metal shavinings can get inside the piston chamber and ruin plugs.
