Well I got my CHT out finally, This doesn't look good Options

[Nozzle]

In preparation for the trip to Hershey this weekend, I wanted to troubleshoot some very poor cold starting that had developed recently. To check the health of the CHT sensor I pulled it so I could verify cold and warm readings. Odd thing was how much effort it took to remove. I'd read these things should snug but not be in very tight. So I finally got it out and this is what I found:



I'm no expert but that sure looks like aluminum filling in the threads. I have a correct replacement but I'm worried about trying to thread it into the head at this point.

So my question is how screwed am I now and what is the best way to go forward? Any thoughts or experience in this area would be much appreciated.

Thanks,

John

I have a core motor that came with a CHT spacer that acutally screwed into the tin screw hole by the intake manifold. Thankfully it doesent need to be in that exact spot, just anywhere in the head that it can get proper heat transfer and grounding. This should not keep you out for long.
