what have i done???

[jonesy3194]

hey, i have a hyper 21 engine, and today i went to remove the glow plug to unflood the engine and it was quite hard to unscrew the plug, and i finally got the plug out and when i went to put it back in i couldnt get the plug to start to screw, i took a look at the plug and there is no thread on it so i got a different plug and tried it and it seems like the plug is to small for the hole as it wont start screwing in but its the same plug type of plug that i had in there before. what have i done to my engine? and how can i fix it?

seems like you have stripped the thread in ur engine where the glow plug mounts.
Proberly need to replace the button head on ur engine or if it built into the cooling head then a new cooling head

oh ok how do i tell if its a button or the whole head that needs replacing? would it be cheaper to buy a new engine instead of buying a new head cause i have heard the cooling heads are like $100 and the engine is probably only worth 175 tops? if so what engine would you suggest

Remove the head. Then you'll know if it threads into the base of it or into a separate button.
Custom cooling heads are only in the 30-35 dollar range.
