Hi Have a 32 Luhrs with 454's. My heat exchanger is leaking from the cap on the starboard engine. I switched the cap out and she is still leaking. To test the validity of the new cap I switched the port with the starboard and the starboard is still leaking. Do I need to replace the entire heat exchanger or is there another fix?
