I recently bought a 79 LeSabre turbo engine with a rebuilt turbo on it.The turbo is a newer model with an .82 exhaust scroll.It has the usual oil inlet and outlet on the center shaft assembly.But,it also has 2 half inch threaded ports spaced 180 degrees apart.I have 4 other Regal turbos that do not have these ports.Can anyone tell me what these ports are for?
