I have 1994 K1500 that's leaking Oil from the Oil Filter Adapter housing bad. I've replaced the gasket numerous times and everytime I take it off and put it back on, Oil starts flooding out where the block meets the Adapter upon start up. I've only gotten it to work by keep taking off and putting the Adapter back on and off until it all of the sudden stops flooding out. It still drips a good amount even after that. My Adapter has the oil cooler lines too. Surfaces are clean, I've tried all gaskets, even ac delco. Adapter doesn't appear cracked or warped. I plan on pulling one from the junk yard, but I was interested if anyone else has experienced this. Has a somewhat fresh motor with high pressure pump, oil pressure at idle is 60psi and full throttle is 60psi lol not sure if there's a problem but thought I'd put that out there too. Any similar experiences or recommendations would be great. Thanks
