Idon't have a panel or burb but my 61 Apache w/235 does not have a line to the right side of the engine. Before I got my truck from my DaD he must have changed it. At the tee on the block one lie goes to the filter (straight through) and the other goes to an oil pressure switch. At idle it runs about 25 lbs of pressure and while driving under normal conditions it runs about 30 - 35 psi. just curious as to whether or not all 235,s had the other fitiing by the plugs.
