so i noticed i was dripping oil. i have a glowshift oil pressure gauge on. so i got it jacked up and seen where its leaking from. and started to tighten it down and the thing snaped inside of the engine. how can i remove it. the adapter is the autometer 2278. goes from 12mm male to a 1/8 npt female. i broke the 12mm inside the block.....help

the location of the spot is underneath the header. there's 3 plugs there

 

Get your self a EZ-out there a wedge shaped pin with sharp edges,you tap it into the broken pipe with a hammer and gently turn the broken piece out with a wrench.
Make sure its big enough to fit the hole in the pipe properly.

 

ya my dad said to use that. so its out thanks.
