Cold oil filter, crusader 270
recent oil pump replacement in engine. Noticed oil filter remained cold after engine is very warmed, hot. Have (1982) twin crusader 270's the other engine runs hot oil filter. I did notice the oil hoses were crossed on the cold filter. I switched the hoses and the filter warmed up, next day ran engine and filter remained cold again.
I removed remote filter system from engine. The engine adapter plate, hoses, oil filter adapter and filter. Filters are napa gold 1191. In any of the remote filter setup there are no check valves or obstructions, there is free flow (air) between all parts. On the engine cast block I see no check valves, just oil ports to and from engine.
Am I wrong to assume the oil flow is from oil pump to the block, to the outer section of the engine adapter plate, down the hose to the outer side of the oil filter adapter to the outer shell of oil filter, out the center of the oil filter up the hose to the center of the engine adapter and onto the engine oil passages.
I have 70 psi oil on startup, 50 psi hot running, 1000 rpm. Why do I have oil pressure to the engine and no or very low flow through the filter?
Is there a built in oil by pass in this system anywhere?
Thanks for any enlightenment.
