After letting it sit all night with a heavy spraying of PB Blaster, I attached vice grip pliers and twisted and pulled and it came free. You can see from the pic that only about 1/4 inch was all it would come out and the slurry of carbon gunk on it when it finally came out.

Just for reference--the elephant pipe or the corrugated pipe screw (the one you access from underneath) is a Torx-T30.. The manifold screws are Torx-T40.

My glowplug light went out, but the check engine is still on after replacing all 6. Hopefully a trip to Autozone to clear the code will fix this.

Great post--saved a ton of money. Took me a long time, but next time should be easier as my learning curve went way up.

Thanks a million.
