Oh yeah they do. But it shouldn't be in the cooler loop. They will hit 250 to 300psi internally when commanding shifts. But the cooler loop is not like that and more like 30 to 40psi. And the temps post-cooler should be moderate presuming that installation.
We don't know how the OP installed this or in what, he was vague. Sounds like a Toyota or Lexus, though. Problems with an aftermarket mount, lines, etc. could explain it. But, I used to use this filter but quit because they would not hold oil overnight after 2k miles installed - the ADBV or base would just leak down. The massive number of Purolator failures is becoming legion. The OP can explain the installation more but the suspicion falls more on Purolator (and Motorcraft for not rectifying it when they've known about the issue for a few years now).
I just wonder why Motorcraft doesn't care. They have known about it for years, they know consumers know - or at least the informed minority. And they do nothing. Seems like the spirit of Lee Iacocca is alive and well.
