SOURCE: head gasket blown
there are many was a head gasket can blow . sometimes they just leak to the outside sometimes they leak to the coolant and then it blows out your antifreeze. if you have a blown head gasket you will see it when you pull the head. and yes you should hace the head checked at a machine shop and install with a new head set never reuse a gasket .

SOURCE: blown head gasket
I would change both, as well as use new head bolts. Make sure your heads are not warped or cracked, especially the one that is leaking. There may not be any need to change the head if it is not cracked. These are prone to blowing a gasket especially after 150K miles or so. It will not cost a huge additional amount to change both head gaskets since the engine will have to be disassembled down to the heads anyway. Hope this helps you, Rick

looks like there is special sequence to reassemble and tightening, a quick note replace any bolts that have two punch marks.tighten as follows: x x x x x 10 4 2 6 8 x x x x x 7 5 1 3 9 torque all down to 15 ft lbs torque to 30 ft lbs plus 90 degrees. Good luck!

the "sniffer" in this case is a device to detect the presents of combustion gasses in the water or radiator .... if there is a good head gasket seal then there should be no combustion gas in the water .... if there is even a small leak then the high pressure gasses will be forced into the water .. the opposite is true when you turn off the engine ... as it cools, pressure in the radiator can force water thru the leak back into the engine .... this also happens during the intake stroke .. so you would be losing water that you might see or smell come out the tail pipe ...the fact that the failure has happened a second time might indicate that you had a warped head or block .. or perhaps a micro crack or surface flaw.. those things should have been checked when the last repairs were done ... i am wondering if the repair shop might negotiate a reduced rate for the redo ... often heads are slightly machined to remove any warp or surface faults during such repairs (if any problems are suspected) ... a used replacement engine could have the same problem or worse .. so if yours is otherwise in good shape then it might be worth while to give it another go ,.. sounds like a good garage, hopefully they will cooperate ... and they might be interested in finding out themselves what happened ...
