High oil pressure after oil change??

Pump relief valve sticking? All it takes is a little crud in there. Or maybe the gauge shat the bed on you.
The thing with the filter is....where's the oil pressure gauge sender? After the filter. So if the filter was plugged or restricted shouldn't that cause a LOSS of pressure at the sender? I think so...and a filter with that much restriction should open the pump bypass (70psi?)

Aw sheeat @spl440 you said it first....I didn't see your post:rolleyes:
