So I scored an Oscar for $600 delivered to my door and the owner said he replaced the temp thermostat and disassembled and rebuilt it from the boiler up, descaled everything and reassembled it. Seems pretty good to me but I was just wondering if there are certain test I should do to make sure everything is in working order.

Congrats!
Start at the simple, look it over and see if it looks like what it was represented to be. As I remember, the top is pretty easy to take off and if it was rebuilt, desclaed etc, it should be clean, the tubes should be clean etc.
If that passes inspection, leave the top off but put water in it and see if it holds water! If so, GOOD, you are on your way!

If no leaks are seen, plug it in and turn on with at least the top off so you can see any possible leaks as it warms up.

OK, it is hot, no leaks, you have bled the false pressure off of the boiler after it has been on for about 10 minutes, do this from the steam wand, open for a second or two then close, the machine will continue to warm up.

Get out your scale and grinder and give it a go!, pull a few shots. Most likely, you will have to adjust the grinder as it will have a little more oomph most likely than you are used to. Dont forget to get out your milk and pitcher and be ready for things to happen FAST!

If it all looks good, put the top back on and enjoy..... until the mod bug bites!

Wow seems like a lot to take in. How would one bleed a false pressure valve ? I mean one reason I chose the oscar is that it is popular so I was hoping there would be a lot of tutorials. My first HX machine so kinda a step for me.

Hi,

It is really pretty simple.
if it holds water and looks like the seller said,
plug it in and turn on. Let it warm up about 10 minutes, that should be plenty of time, likely it will be ready in 5 minutes. Turn the steam wand on, it is a push button on the Oscar. Let the seam wand be on for a couple seconds then turn the steam off.

Bingo, you have done it :D

Oscar is a great value and a quality machine. One feature it does not come stock with is a vacuum breaker. It is not a mandatory thing for sure but it means you can not put it on a timer, at least not until you add one. It is a pretty simple thing to do if you are fairly handy. You simply cut the copper tube from the boiler going to the group head,  then install a T fitting an elbow and the vacuum breaker, oscar is now able to be put on a timer but that will come with time :D

Steam is a knob on the left not a button, sorry Cal.

Have you checked out our video?

Plindy knows more about the Oscar than anyone outside of Belforte del Chienti, hands down. However, only invoke this mystic oracle's name if you are absolutely stumped after doing your research. Enjoy the Oscar, it's an awesome machine!

I think he doesn't need trouble shooting yet, just reassurance.   If the seller did what he said your Oscar will not need trouble shooting for a long time.  They are robust machines.

Ye I mean I always like to be safe when buying second hand but I think it's safe to assume especially with higher end machines that they have been taken care of
