Thermal Pellet plug is stuck in e shaft
ok so in my engine there is a thermal pellet plug, it has been forced into the e shaft further than it should have due to an rx8 front pulley bolt used. the plug is now seized or stuck in the e shaft about .250" further than it should be due to the longer rx8 bolt.
at first i could not tighten the short front pulley bolt all the way. so we shortened the bolt about .250" and now the pulley tightens all the way down.
i know this is dumb and i tried removing that plug, although i didnt try heat yet. the plug is aluminum and shaft is steel no not sure if heat would work
also I am not sure if its a bad thing that it is stuck. the location and length of the plug doesnt really block restrict or damage anyting so i may be good to go.
here is the plug
it is .250" further than the oem one pictured
here is my shortened bolt
and everything assembled nice and tight

I know that sounds stupid. A longer rx8 main pulley bolt caused the plug to be seized. and its not far enough down the shaft. it doesnt make sense because if it pushed it too far down, then the stock bolt would work. but it was too long

I purchased the engine from a guy and it had the longer rx8 bolt in it
When i went to put the correct bolt in, it wouldn't tighten completely and the main pulley had .250" play
So we just took the bolt and lathed down .250" now the pulley is nice and tight

most likely, i've never had this issue but i also never tried putting the pellet and spring in without putting all the proper parts in place. you can't tighten down all those components without the hub in place to act as a spacer.
if it were me, i'd dig out the pellet and spring and replace them, get a new e-shaft bolt and call it a day.
this is like trying to re-engineer a screwup to fix a $20 mistake.

I did install the hub and it had a quarter inch play....
Also I did attempt to remove the plug, only with some needle nose pliers. It didn't budge. Im sure some heat would help.

I dont want to damage anything or put metal shavings into the shaft so i am just going to leave it. I dont think it will hurt anything being in there and if it loosens up later, then i will replace it with another bolt and thermal pellet.
