I had a finished my engine swap done a while ago. Problem now is that I do not know exactly which oil pan would fit on this block. The engine that I have is a b16a. Do I use a pan from a 99-00 Civic Si(B16A2) or a 94-95 Del Sol(B16A3)? I have already threaded the oil pan once already. But now it is dripping really bad out of the pan now. It is leaking from the drain plug. Thanks for any help or insight.
