Guys I have an original 92' SIR civic B16A engine but my issue is an oil leak right now. The following is the changes I made with respect to this: Crankshaft seal Camshaft seals (both of them) Main rear oil seal Oil sump pan gasket Tappet pan gasket All original honda parts as stated above. In addition jus to mention my oil pressure switch and pcc box are also fine. However I have a small leak still. Can anybody assist me?
