318 expansion plug leaking

Spent the day changing some sensors. Installed the rubber plug and flushed the whole cooling System. She's up and running b with no leaks. Now for some nice weekend days so i can start the interior work for the carpet. Thanks for all the tips. Was able to loosen the headers and get my hands in there. If any more decide to go I'm pulling the engine and building it up a little before it goes back in.
