I have a blown head gasket and i just started by draining the oil. It was oil all the time that i was looking at it. Then i started to take the heads off and i needed to move my headers alittle so i got under the car and was going to unbolt the flange. I started to jack up the other side of the car ( i already had the front left jacked up) When i jacked the right up anifreeze started to drain out of the oil pan. Hopefully that is because of the blown head gasket right? If not, im in trouble.

 

thats DEFINATLY because of the head gasket

 

More than likely it is a blown head gasket. Does/did the car overheat?

 

I never looked at a lt1 block with the heads off but if you pulled a bolt out of the head, you could get coolant into the engine that way. Some bolts go through the water jacket on the block.

 

When you pull the heads coolant will get into the cylinders. This is just normal, not head gasket related.

 

If the car has been sitting a while, and there is coolant in the oil, it will come out first, then oil. If one side was jacked up, the coolant could have shifted, I don't know.

Started on the heads means you loosened any bolts? If so, they are right coolant gets in the cylinders and probably leaks down (not necessarily a big deal, just got to soak up the any coolant that has pooled up in the cylinders). But, it is either from blown head gasket, or from coolant leaking down through cylinder. So you are not screwed (aside from the blown head gasket )

Hope this helps.
