Triumphisti,
At the risk of reopening the dreaded spin-on oil filter thread, I
have a question concerning the Fram PH3600 filter. As I recall, we
concluded the last round with the verdict that this filter had both a
drainback valve and a bypass valve. Today at Trak Auto, I was comparing
filters and I could see the drainback valve, but no evidence of a bypass
valve. I went with the Motorcraft FL-400A, which obviously had both
features.
To the lister who suggested the Fram, are you sure it has a bypass?
