Ive Got A 91 Crx With A 90 Block And A 93 Head(d-series) And Its Leaking Oil From The Distributor So I Replaced The O-ring On It. It Is Still Leaking So I Went To Hondaland And Talk To A Guy Who Said It Is Because The Head Is Obd1 And The Distributor Is Obd0. So My Question Is Is That True, And How Would I Go About Fixing This Problem.
