Ended up taking the wrong plug out that I wanted my stupid self ended up dropping it in the engine bay. Spent an hour looking for it and gave up. Trying to find what size it is so I can get a replacement and move on.

 

A friend got back with me saying it's a 1/8" BPT plug.

 

Putting an NA motor in your NB?

 

94 motor with 9.0:1 CR and only 54K on the clock...dont see the problem

 

yeah im willing to bet its 1/8 british standard pipe as said above. a 1/8npt would prob work

 

Yes, it's 1/8"BSPT. 1/8"NPT is close, but you will end up cross-threading it (might seal fine though). 1/8"BSPT is 28 threads-per-inch versus 27 for 1/8"NPT.

Thanks everyone. Hustler, nah the picture is just a reference.

 

Well, that's good to know. I was going to give you grief about that thing bolted to the crankshaft where the flywheel ought to be.
