rags Posted June 20, 2004 Share Posted June 20, 2004 Anyone know if the thread size/pitch for the oil filter is a M20 x1.5 or a M22 x 1.5 ? I'm looking to buy a sandwich adapter to mount an oil cooler. Thanks. Joe Quote Link to comment Share on other sites More sharing options...
Synlubes Posted June 20, 2004 Share Posted June 20, 2004 L-series blocks (4 & 6) 3/4 x 16 Quote Link to comment Share on other sites More sharing options...
Doug71zt Posted June 20, 2004 Share Posted June 20, 2004 Joe - Anything that fits a small block chevy should fit the L6. Both take the same oil filter - PH8A Fram. That should make the adapter pretty reasonable. Doug Quote Link to comment Share on other sites More sharing options...
rags Posted June 20, 2004 Author Share Posted June 20, 2004 Uh oh. I hate when this happens. Isn't a SBC 13/16" x 16 and a Ford 3/4" x 16? Two answers that I'm interpreting differently. Figures. Help! Quote Link to comment Share on other sites More sharing options...
Guest BigWhyteDude Posted June 20, 2004 Share Posted June 20, 2004 My Dodge truck uses FRAM PH8A aswell, hmmm Andrew Quote Link to comment Share on other sites More sharing options...
Guest cool78Z Posted July 5, 2004 Share Posted July 5, 2004 Yep. Its a 3/4" - 16 straight thread, per my Fram book (ca 1971). For Mopars, Fords Kaiser Jeep(!), Volvo, etc. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted July 5, 2004 Share Posted July 5, 2004 PH8A is a Ford Filter and works on L series blocks. Quote Link to comment Share on other sites More sharing options...
