I had it plug a heater core once. My Grandfather always put pepper or raw eggs in his. They both worked. He also ran 20w 50 year round, threw hot water on his windshield to thaw the frost, ect All of which I would not recommend, but it all worked for him. I still have the engine from his truck, 1978 350 with 250k on it. I think I would run with the cap loose and see if that slows it down. I have had several radiators over the years that would leak pretty bad under pressure, yet I could live with it with the cap loose as it pushed less out.
