Coolant in cylinders

[bav70ss]

We pulled the heads on my 67 Nova SS with a 327 and found coolant in the cylinders. Both headgaskets were toast on my new 700 mile motor. Any ideas as to why this would happen?

If you did not drain the coolant from the block, then just pulling the heads will allow residual coolant to flow into the cylinders.

If it was clean looking, that may have been what happened. Impossible to say without looking.

What were the symptoms?

Interesting ... I have heard of using bread when attempting to remove a pilot bushing but have never heard of anyone using toast for head gaskets. Me thinks that might be the problem

If you had steam coming out of the exhaust then you had bad head gaskets or a crack somewhere. If you didn't then it probably just ran out of the block and into the cylinders when you removed the heads.

The coolant was clean...a straight 50/50 mix. The motor actually hydraulic'd trying to start it. Very weird that both head gaskets went. One was severely compromised. I will try and post some pics.

Gonna need a lot of pictures.

Any mods to the block or heads or intake?
