i have an 88 trans am 5.0L F and its got a blown head gasket, but i just wanted to start it up today just to hear it run for a few seconds, and when i had a 100% charged battery and it wouldnt turn it over, so i tried another new battery, still didnt work, as soon as i hooked up the battery, it just ran out of juice, so then i took the huge battery out of my dads truck, and got it started, but any idea what the issue is? related to the blown h/g, or somthing else?

 

It may have been hydro-locked, and/or the coolant has already damaged the bearings so it cannot turn easily. Either of those depend upon how much coolant may have been in a cylinder and/or in the sump.

You may be looking at a significant repair, but at least need to check the condition of the oil. If there are any signs of coolant in the oil, the damage may already be done.

 

so if there was a significant amount of coolant in the oil, what kind of damage would i be looking at?

 

any more details vader? or anyone else who may have some info on the subject?
