Perhaps there are different 318 poly blocks. Maybe my 318 poly engine is originally from a truck? The oil filter that the Autozone gave me STP s8a screws into place but needs to be much wider to seal to the engine block. I think I found an adaptor on eBay that may fix my problem. What do you think of this? I would much rather have the filter that came on engine originally. But maybe they don't make the old filters anymore. What do you guys think?
