It is kind of a long story but I'll describe briefly what was and what is.
My engine is a 49 - 53 hipo with Merc crank and 3 3/8 bore. The motor has about 2000 miles on it since completely rebuilt. it ran great with no smoking until i put in synthetic oil. When it started smoking out of the passenger's side tail pipe my friend told me to go back to 30 weight non detergent oil, because synthetic is a horrible break in oil. He said to put on about 800 miles with the 30 weight and the smoke should go away. Well after 200 miles it only smokes when the engine is warm and when I rev up in place. As i drive on the highway the smoke goes away. The second spark plug in from the front on the passenger side is always wet and I think it is fouling out but dont know for sure. All the other plugs are clean and dry.

Do you think if I keep driving the situation will continue to get better or am I going to have to pull the motor and break it all down...damn I hate to think of this?

Thank you,
Guy
