We just picked up a 56 vicky ,had not been run for 5 years, when the owner passed away. I got it  running , starts up , runs fine , but after a minute ,it starts smoking from the left bank. The motor is either fresh rebuild or fresh paint. There is no blow by. When I get back to it in a few days, off comes the valve covers , compression test , I am thinking it's a top end problem . Anything else to look for ?
