Oil blow out question

    300cc liquid cooled 2 stroke

    First ride, over heated, blew coolant out of the over flow.

    Changed to Evans, no issues since.

    Go to change the oil tonight. The transmission, and engine oil are in the same compartment. Per the manual, and let it idle to temp. Start backing the drain plug out, and BOOM, oil, blows out, everywhere. I'm talking head to toe covered. 12' diameter around me, soaked on the ground.

    What in the world would cause there to be so much pressure, in the transmission?

    Blown head gasket?

    Other?

    Thanks

    Transmission oil and engine oil in the same compartment?

    You sure it's a 2-stroke?

    Plugged pcv? You must have shut it off on compression after compressing the crankcase.

    Reason #1001 to wear safety glasses, even when there's no apparent danger in the procedure you undertake. Can you imagine having pressure-washed your eyeballs? I don't even wanna think about it.

    Does the transmission have a vent?

    The only other possible culprit would be leak between the engine and the transmission, possibly a bad crank seal?

    Not sure about a vent. I'll research more tomorrow.

    Has to be the trans vent plugged.

    Were you in some really gnarly stuff to overheat it?

    Bad fuel petcock? the Aprilia rs250 had a run of bad petcocks that would fill the crankcase with gas

    Yeah, wrong bike. Was totally flustered when I posted. And covered head to toe in gear oil...
     
  19. You took an influx of formation oil because of an underbalanced situation due to insufficient hydrostatic pressure in the drilling column (typically caused by poor displacement management during tripping operations, contaminated drilling fluids, fluid losses into the formation, or by not strictly adhering to the weight-up schedule based on expected pore pressures).










    ...but im sure it was BP's fault.

    Do you work in the oil/gas industry also? Or are you just quoting the deep water horizon movie?
