oil cooler bypass

    I know all the possible reasons to not remove the oil cooler from a 1992 Suburban. But this particular 454TBI now lives in a different vehicle.

    Question: If I choose not to run the oil cooler, can I just plug the inlet and outlet or do I need to make a loop to maintain proper oil flow?

    Thank you

    Good find! This is good information on the bypass valves.

    So I have read the bulletin and I have read the Chevelle forum. Bottom line: If I do not want to run an external oil cooler I should pull the bypass valve out of the center of the oil filter connection (number 4 in the diagram) and plug the inlet and outlet (#1 and #2) originally feeding the oil cooler. Right?

    That's correct.

    Can anyone tell me what the bypass valve looks like? I know it comes out of the center hole, but I would like to make sure I am not pulling on the wrong thing.
