Could you take one that's in focus?

here is from the top with silicon over it to stop brake fluid going everywhere

I hope you don't need to as it's not cheap....

But If you require a fully rebuilt and re-sleeved BMC (BM50 - ABS model for Sumitomo callipers) - PM me

I have one just done in may 2013. I have the invoice as evidence and will give you a good discount on what I paid

It has not been fitted and still in box.

I think that little hex plug that is wet in your first photo and glubbed up with silicone in your second is just a plug. It might be a set screw for the prop valve, but I haven't actually dismantled one of these myself.

There is a rebuild thread about a LHD Z32 BM44 ( http://www.aus300zx.com/forum/showthread.php?t=311875 ) that shows a dismantled drawing that indicates that the screw in question is a stopper or limiter of some sort and has a seal/gasket under it.

It shouldn't leak. Mine is ever so slightly damp with brake fluid and has been forever, so maybe they have a slight tendency to weep out of there at the best of times. I reckon you can't do much to fix it where it is, so you'd probably be advised to take it off, take it to ABS or similar, and get it rebuilt with a stainless sleeve etc etc. At the very least, a quick visit to a brake shop would be worthwhile to find out if they can deal with it quickly and easily or not.

did some more digging around on the net and people seemed to be puzzled by this middle port
