I have a 87 supra.. I had a 7mge but a BHG forced me to do a swap.. I'm almost finished but I'm having an issue with coolant leaking on the turbo side. It seems to be right by the manifold towards the end of the engine but I'm not sure.. there's a hard line coming off the engine right by there that I was told to plug off.. I think its the issue.. I think the pressure is being redirected to come out by the manifold.. I'dplug it but I have no clue where to connect it to.. anyone ever had this problem? here's a picture.. the white piece is a plug.. when the plug is off coolant goes everywhere.. I'm thinking its causing my issue so I'd like to find out where it runs to
