Alright, I have a small problem in a very big way.

The adapter for the pcv hose melted onto the threads of the hole where it attaches to the intake manifold. See pictures.

Any ideas on how to remove the plastic from the threads?? I've tried unscrewing it, dissolving it, chiseling away at it, cutting it, "sanding" it, and melting it. If you have any unique versions of these techniques, please let me know. Better yet, if you've ever had the same or similar problem, how did you solve it?

 

Plumbing section/sprinkler parts have a tool used for removing broken pipes out of pvc fittings.

If not, remove intake and use a long socket extension and beat out from behind.
