Hi Dave,
If it is leaking "just a little bit", I would ignore it. I tiny air leak at
that point is equivalent to blowing thru a straw compared to a hurricane.
To put it in perspective, think about the amount of air being sucked in by
the 360 cu in (or more) cylinders about 20 times each second. (360 x 20 =
7200 cu in compared to a "just a little bit". My opinion only.
