If the intake o-rings leak is it a visible leak? Can you usually see gas? Thanks
Generally when intake o-rings wear out, you can see a kind of a tobacco colored
stain around the bases of the intakes with the worn out o-rings. Mine were that way.
I'm not sure what would happen if they were so failed that liquid was leaking out, but
you'd probably know (blindfolded) that something was wrong...
