now my computer wont load the picture but my best guess would be some sort of engine flush they sell at autozone man

no need to repost man.... its not an instant messenger people will eventually read yours and i already answered your question.

compressed air, then you can clear bolt holes with a tap and die set....

The picture is blurry, but what I see is antifreeze in the bolt holes and a lot of rust in the water jacket.

I have always run a head bolt all the way down each bolt hole to force and liquid out and mopped it up with a rag. It would be a good idea to run a tap down each bolt hole to clean out the threads.

As to the water jacket, the best fix would be to strip it down to the block and have it hot tanked at a machine shop. Other than that, there are block drain plugs and you should remove those to drain out all the old coolant then run a cooling system flush and drain and refill the cooling system with new antifreeze/water 50:50 mix. This is a good time to replace your radiator hoses and heater hoses as well.

Whatever you do. Do not ever run a bolt into a threaded opening that has any amount of water in it. Water will not compress and I've seen pressured water create fractures in casting when a bolt or stud has been treaded into the opening that had water in it.

That could happen if there was no way for the water to escape, but there is enough gap between the bolt threads and the threads in the hole for a head bolt that the water is displaced out of the hole. I'm talking about running it down with hand tools.

for that to work you would need to use a bolt that is slightly smaller than the bolt that is suppossed to go into your heads. Even with hand tools your causing pressure.

Well I've always done it this way and you can see the water come out of the hole past the threads. It's not a tight enough seal to create any significant hydraulic pressure. Clearly if the water is leaking out at a rate greater than or equal to the rate at which volume is being displaced by the bolt there is no hydraulic pressure. If the hole was filled with something much more viscous like grease and the bolt was run in rapidly and forcefully, I could see hydraulic pressure causing damage.

Another option would be to use the next smaller bolt size to increase the rate of water leakage past the bolt as you suggest.

It is also possible to blow the water out with compressed air, but most people working at home don't have access to compressed air and there is some risk of an eye injury or the like with compressed air.

Cool. I'm just stating what I've seen happen in the shop.
