Replaced the water pump with new one. I had cleaned the block with a wire brush on my electric drill, put RTV (gray) on the block and on the pump with the gasket that came with the pump. After install, I had a leak around the bottom of the pump, just a drip. Went and got a new gasket, cleaned the block and pump, as before, put RTV (gray) on the block and on the pump with the new gasket. Still had a leak. Went and got another gasket repeated process, but this time I put the RTV (red) on the block and pump and let it cure for about 45 minutes, put the gasket on and installed the pump, I just hand tightened the bolts and let it sit over night, with a shop light shining on it because it was in the 30's over night. This morning I torqued them down to 10 ft/lbs. Still leaking around the bottom of the pump. Torqued them to 15, leak, 20ft/lbs still leaking. I am tired of messing with it, and need some advice, any help would be greatly appreciated.
