Critical? Could be....if the engine happens to turn off with that particlular exhaust valve open.....a couple of things could happen: 1) The cylinder could fill with coolant - this could be extremely hazardous if the engine were to try to start and the valve were to close (50/50 chance) while the cylinder were full, BOOM! (or it just wouldn't crank over). 2) The coolant would by-pass the rings and enter the crankcase, fouling the oil - Goodby bearings! You *did* check the condition of the oil didn't you? Diagnosis: Pull the plugs NOW and see if there is one (Hopefully ONLY one) that shows coolant fouling. -- "Our eyes and hands and feet will give us the same assistance in doing mischief as in doing good; but it would not therefore be better for the world, that all mankind were blind and lame. Arms are not to be laid aside by honest men, because carried by assassins and ruffians; they are to be used the rather for this very reason." -George Campbell (1719-1796)
