    well before spraying it why not try to suck the air out of the crankcase somehow (vacum ??) .

    . if you depressurize the innards… the paint should get sucked in the seam and close it up good

    conversely .. before you spray paint it… if you pressurize the crankcase (both pistons closed half way if possible with exhaust ports closed) you could spray it with some soapy water to ""find" the bad seam

    ho well… back to web surfing
