Broken and seized Glow Plug tip

[LN106G]

Then you're S.O.L. The surest way is to extract them with the cylinder head on the bench and might as well clean and lap the valves, change the seals

that is the most likely scenario. ala top overhaul na in a definitely healthy engine just for that s**#^%d broken glowplug tip. But i'll have it in a "double set up" (tanggal ang CH kung mag fail yung pag dukot sa taas).

BTW, what do you mean by S.O.L.? haha
