Im goin to look at a 85 300zx turbo tomorrow a buddy of mine is selling it to me. There is a problem with the clutch he was headin to work one day an the clutch had no pressure after he pumped it a little bit it pumped up an he got to work. We talked to a mechanic at work to get fluid he said use brake fluid its the same so he put it in about a day an a half later it was empty or has a little left in there an has no pressure what could cause this he is sayin leak from the reservoir or something between there an the tranny? It sounds like a leak but im not sure I wanna have an idea of what it could be.
