I have a mazda rx7 Turbo2 cranked it today after 30 years + sitting. It ran good for about 20 sec they shut off. I found oil an gas leaking from flange on the exhaust pass turbo can someone tell me what might be causing this to leak. Would love feed back.

 

too much fluid, the exhaust gaskets seal air, but not liquids. if you run it enough to get it warmed up it should burn all the junk off and be ok
