Well problem is found already. Head gasket is blown thats why there is coolant is that cylinder. Also its very possible that the head is warped or cracked. Bring car to mechanic asap.
uh you still wanna get it checked.
Can be, but not necessarily.I thought a blown head gasket is always caused by overheating. Yes? no?
Pull head, have it hot tanked and cleaned, checked and resurfaced if warped. Replace headgasket and other bits that you can. Reassembly is opposite of removal. Done
