I assume you have the 91+ oil cooler? If so does it seem like the screw is backing out? It's a common problem. You'll want to remove it, clean everything really well with brake cleaner, put a little lock-tite on the threads and reinstall. You do NOT want to torque it tightly. Just a little bit. Torquing it too tightly can damage the oil cooler and cause oil and coolant to mix.
