Both these oil filter have the same specs I think, thread size filter
but one the b1432 baldwin has an antidrain back vale the other does
not pf-61 ac delco
my pf-61 mounts vertically so no anti-drain back is needed as it will
not drain once the engines stops.....
the b1423 has an anti drain back and mounts horizonatally in my jeep.
When the engine stops the oil drain out slowly because the valve stops
If i use the b1432 in place of the more expensive pf61 the only
concern might be the loss of oil to the landfill on changing teh
did I get this right
