Im desperate.

You've probably done enough damage already and you should give this to a professional. He first has to find a way to get the extractor out because it is hardened steel and cannot be drilled. After that he has to somehow repair the alignment of the hole and install a heli-coil.

Other than that, you are buying a new manifold.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Spot on HT - OP send this out. You couldn't cause more of headache then breaking an easy out off too in the thing! Still could be real trouble or lot of time depending on what engine this is,
