Should have explained this a little better, because it isn't the
position 'at rest' that's important.

What happens is that the breather junction on top of the cam cover gets
old and soft.  It's then unable to support the breather tube that goes
down the side of the block in its normal position during acceleration.

That's why you see this problem in low gears when accelerating.  In
place of an elegant solution, just tie-wrap the sucker to the plug
cable shroud.
