My brother has a 350 out of a '95 Tahoe in his '88 formula. It still has the oil cooler adapter installed. Well we went to go replace the oil cooler lines and they are rusted stuck in the adapter. After removing the adapter we were able to remove the big "nut" type things that screw on to the adapter that the cooler lines go into. There is no way we can get the lines out without killing the "nuts".

So my question is, if anyone has done this, now that i have the "nuts" off i can screw a cap of some sort on the adapter and block off the 2 cooler line holes. Can i do this? Or is the cooler adapter designed to have the oil go through no matter what. I'm not looking to blow up the motor. But we're kinda in a pinch. TIA.

i cant recall how we did it with my friends 88 GTA but we removed the oil cooler completly. on my friends 87 GTA we just left the lines and the adapter on the car and re-routed the coolant lines. the line that goes from the rad into the cooler line, just un hook it and re connect it to that metal line where the coolant line comes out from the oil cooler. the out line should be L shaped. this will bypass everything with no issue.

the metl line i speak of is on the frame next to the AC lines.

Do you want to completely remove the oil cooler? If so, you could put one of these in place of that oil filter adapter and then take out all of the lines and cooler.
