MD RX-7 FC Turbo II Coolant Leak! HELP!!

I have been noticing coolant coming from the rear of the engine down around the transmission acess cover Plate between the engine an Trans, its not a huge leak more like a small dripping one, but it needs to be fix where ever its coming from ,The coolant will drip from the right side of the engine between the engine and trans around the acess cover, Took the transmission acess cover off didnt see any coolant nothing was wet,so now im stumped does anyone have any advice to where its could be coming from, Iv checked all the hoses and what not ,everything seems to be fine, Am i missing any hoses around the rear of the engine!

Its most likely the stupid turbo coolant passage o-ring it goes between the lim and the block and has been the cause of many annoying coolant leaks and failed gaskets.

Freeze Plugs seem to be fine from what i can see through the access cover, Come to find out earlier in the year i had and issue with the coolant gathering in the valley under the throttle body, i thought it was leaking from the hose that comes of the rear iron but took everything off and it was fine,so im starting to agree Sharingan about the coolant O rings, because i got to looking around and i could see where coolant or something wet has leaked around the bottom of the intake manifold right above the exhaust manifold so i orderd the parts so im going to fix that and see if that doesnt do the trick. Well see.
