So I just got a Civic VX. Problem is that the oil rings are shot and it is burning oil badly. It is also misfiring due to the rings letting that much fluid past the rings. Plugs are soaked with oil. Here is my question. Is it worth rebuild the Z1 and hoping the block and head have no damage or should I go to an importer and get the D15B Vtec-e from them? They are the same engines. Any insight?
