Salvage Yard Question

[NOT THE BLUE LAMPSHADE]

I recently swapped a new engine into my Mazda 626. I got an engine from Viking Auto in Northfield. I've had the engine in and running for about 6 days now, and I've driven it not even 250 miles.
2 days after I started driving it, I discovered the rear main seal was toast and I'd have to drop the tranny out to replace it, since it's not a 2 piece rear main.
Saturday, it started over heating like crazy and I had to have it towed off the highway and I discovered it's the head gasket.

I've gotta a complete shit engine from them!

Does anyone think I'll get my money back or some money back? I bought the engine on the 15th of this month, so it hasn't even been a month yet. I don't wanna have to go pull it out again and try this over. I just want them to give me money to buy a new head gasket and have the head machined and tested.

Just wondering if anyone has had this happen or something similar or know anything about it.
