If you can get the tube area squeaky clean with steel wool and
acetone etc, I'd try that rubber tape that 3M sells to repair
extension cord insulation; very stretchy and then cover it with 33+
or 88+.  Eventually you'll want to do one of those spring loaded
replacements when the time and money are there.  I think they're like
$20 each.  There's no pressure other than the whatever crankcase
pressure is inside the block.

Good luck
