so the car sat for seven months. Just fine with 107K on the stock block. I go to start it and it wouldn't start. Killed a brand new battery. Recharge the battery, change the oil and coolant to store the car some more and change the spark plugs. Now the car fires up every time with no problem. Drove it around the block a few times and it is just fine.

then the car sits for another six months. Check everything under the hood and the coolant is low. I top it off and start the car. It fires right up and after a few seconds the water buzzer sounds. I open the cap and top the water. Five minutes later the buzzer goes off again and I top the water. This time it took half a gallon of coolant. Five minutes later it happens again and I also hear gurgling. So I sweep a flash light around the coolant lines and no leaks are to be seen. Then is when I glance over to the oil fill neck.

The oil neck is puking with the cap still on. Foam is dripping everywhere. So I unscrew the cap and it explodes like a volcano oil/water that looked like someone dumped dark beer in my engine.

How the hell could/did this happen?

 

engine freeze plug popped, it's dumping coolant into the oil system. did you mix it the proper 50/50 water coolant before storing it for the winter?

 

yes, proper 50/50 mix. That was the first thing I made sure of because I knew the weather would be dropping to freezing. So is this fixable? I thought the freeze plug was external and it would have puked water all the floor?

 

just went though gnome311s 28 page thread... I'm better off looking for another engine.
i guess there was still water in the block after I changed the coolant
