Try and clear some plausible causes one by one.
Get the coolant checked for exhaust gaz.
check water pump for admissible flow.
Remove sparks and turn over and taste for that coolant vomitiv taste.
check exhaust fumes for whitish color.
Try and see what's up with the injectors and ignition timing.
check engine bay for any leaks.
edit / Any codes under the bad spark cyl 2, lile O2 sensor? Vaccum hoses all ok ? no whistling ?
Admissible flow? Is that two or three dugga dugga's on the impact?
