This is facing the left side of the engine. If i took pictures BEFORE i took it apart i would not need help now. Thanks | | | | | Joined: Jan 2015 Posts: 192 'Bolter | | 'Bolter Joined: Jan 2015 Posts: 192 | On my '56 235 the center bottom of the filter went to the rear of the engine. I'm not saying it's the right way, but that is the way it was when I got it. I assume it is the right way tho. | | | | | Joined: Jun 2012 Posts: 142 'Bolter | | 'Bolter Joined: Jun 2012 Posts: 142 | Thanks lemmm117,i thought that was correct. | | | | | Joined: Jan 2015 Posts: 192 'Bolter | | 'Bolter Joined: Jan 2015 Posts: 192 | Oh, wait wait wait. I was mistaken. Mine has the center bottom of filter goin to the front oil hole on the engine. I'm sorry. | | | | | Joined: Feb 2004 Posts: 29,774 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,774 | It will work either way, but the most common flex line arrangement is to plumb the line from the oil pressure port (upper position near the rear of the block) to the outside center of the filter housing, and plumb the bottom of the filter housing to the forward port near the oil pan rail. There is a 1/16" hole about halfway up the center post of the filter housing that meters the oil flow through the filter. The conventional direction of flow is for the unfiltered oil to pass through the filter media from the outside, and return to the oil pan through the center tube and the bottom port of the housing.
