The waterneck crossover pipe on my nailhead seems to always leak a little bit of water after the car sits. It almost seems like it is not getting a good seal on the oring where the crossover pipe enters the waterpump. When I start the car and it heats up, it seems like the o-ring expands and seals. Has any one else experienced this problem?
Yes. Do you have two o rings there? There's an upper and lower that seal. Some silicone can help also down in there to seal.
