2011 driven to no coolant - blown head gasket?

I would get a low mileage JDM engine. My engine hydro-locked last fall on my 2010 Prius and I bought a JDM engine off of Ebay. Check with a garage for a quote on how much it will cost to replace the engine and if you can bring your own engine in.

 

Unfortunately nobody (until just now) noticed OP's question, and he only posted the once, likely gone. But just in case:

Leak-down test is best for head gasket diagnosis.

 

Most likely the engine is toast? If it overheated enough to stop? Then it could having bearing and or cylinder wall damage? Not to mention a cracked block or a warped head? It's a very expense gamble if you plan on paying someone to do the job? Likely it would not be much more for a used motor to replace this one?

But if you can do the HG, job yourself? WTH, give it shot. But paying labor rates to have a shop do the job with this motor is a very high risk gamble.

 

Leak-down test is probably superfluous if you have visibly pink coolant dripping in "fairly significant quantity" from the tailpipe.

The test can be more useful if applied somewhere before the sweet-white-clouds-from-tailpipe stage.

 

I agree. Like Dr Mccoy on Star Trek would say "She's dead Jim" The engine was ran without coolant there will be major damage. I would look for a reasonably price low mileage engine to replace the damaged engine.
