Today me and my uncle changed my valvesprings and a couple of things happend. First when we got to the #6 cylinder we got the piston up and and put the air line on to hold up the valve and the cooling system became pessurized Then we go ahead and finish up and start the car and the valve covers are puffing like a train What happend

If the cooling system pressurized the head gasket is not sealing or the cylinder is cracked. I'd expect a lot of blow by with a leaking head gasket. Chances are it's leaking compression into the crankcase causing excess blow by. It's probably been like this for a while. Probably caused by detonation
