MITSUBISHI PAJERO O RING PROBLEM

1997 Mitsubishi Pajero • 260,000 miles

I developed a water leak where the water pipe goes into the engine block. I remove it and bought new o rings. Easy peasy so far. Came to put the pipe back in and just couldn't get all the o ring in - kept bulging out. Is there a trick to this or am I doing something wrong. I've oiled it, tapped it, squeezed it, sworn at it but still managed to destroy 2 o rings.

The O'ring could be of the wrong size. Ensure the tapered section of the hole for plugging in the pipe is smooth and not damaged. A little twisting while pushing in the pipe would help.
