300ZX master cylinder leaking... unknown hole

[matt4pl]

I got everything hooked up and when i started bleeding the system, brake fluid started leaking out of a small port located between teh front and rear fittings. its about 6 MM in diameter and i have to clue what it does. there is no visible thread or anything. i need to plug this thing up or something... car has been in the garage on stands for almost a week with stupid problems and now this. this is a remanufactured tokico master cylinder. any help or ideas would be very appreciated

it should be a threaded plug that goes in there.

got pic?

ok, i got a pic... its a matching Q45 master cylinder but the hole is the same

its the small on in the center

there is suppose to be a plug in that hole.

there was a little rubber one but it popped out im assuming. it was in when i started the install, not there anymore...

JB weld should work, right?
