Onan parts are unfortunatly not cheap and untill recently only available from Cummins/Onan on thier site or thru someone that handles that brand of parts.  Some parts are now being reproduced aftermarket but not everything yet.  Try calling Maple Grove Distributing in Galveston, IN.  They sell and ship worldwide and have excellent prices.  Not that it might be any cheaper but worth a shot.  Dont feel to bad, parts for older Kohler and Briggs are getting almost as bad as Onan prices.  Not all the earlier Onans had oil filters, but the later B and all the P series did.  Yours is just one that does not.  Invest your $$ into the Onan and reap another 20+ years of nice raw horsepower with a throaty roar!   Take your time and do everything by the book, adjust the valves to book spec as well.  Onans are a high performance engine, designed for Generator applications.  They take a bit more care in reassembly than the typical Kohler K series.  Good luck with your rebuilt.   Mike

Many of the Onans without filters have the block drilled for a filter, and a blockoff plate bolted where a filter adapter would go.  I've added a few to engines with such plates.  Just unbolt the plate, bolt on the adapter & filter, then you either cut openings for the filter in the air shrouds, or find used with cutouts.
