Cross Threaded Glow Plug
I bought a used plane off of someone from the field. It was idling rough so I decided to put a new glow plug in. It was kind of tough removing the old one. I think it was cross threaded. I took it out and now none of the new glow plugs want to go back in.
Will I need to order a new head or is there something I can do to fix it? I remember seeing at autozone some stuff that you can put on to the tip of a screw and rescrew it back in and it'll make new threads. But, first I dont know if it'll work for what I need. Second I dont know how it will handle the fuel and heat.
Suggestions?
Its an OS .46 FX Max

You could try to chase it with a tap, make sure you clean the chips out. It may work, or you may not have enough thread left. Either way you would most likely be needing a new head.
But wait and see what others may say.

No, I don't, never needed that info. Hang tight. Sombody here will offer it. Or call tech support at tower and see if they will tell you what size the glow plugs are.

You dont know by any chance what the thread size for a .46 glow plug would be, do you?
Cheers.

RE: Cross Threaded Glow Plug
My dad tapped it for me and it seems to fit fine now. I'm going to run the engine and see if anything leaks or not.
My question is. The previous owner had a short fox glow plug in it. I dont know if he used a short because it wouldnt screw all the way in or not. Why would someone use a short plug as opposed to a standard size?
