If I run into unmovable glow plugs can I use a lubricant to get them to loosen?
Thanks!

If I am reading this correctly, your drain plug has it's hex flats rounded off so your wrench can't get a good bite on it. Try using vise grips on it and tapping them with a hammer until the bolt moves. You might even want to heat the pan area around the stuck bolt with a propane torch for 40 to 60 seconds and then try the vice grips. If that fails, try drilling the drain plug dead center and use a large easy out.
I haven't had much luck with soaking the glow plug with penetrant but I have had good results with heating the area around the glow plug with an oxygen acetylene torch for 30 or 40 seconds and using a six flat closed end wrench to get to get them loose. Once clear of the threads a pair of pliers twisting on the glow plug will clear the carbon off.
