Just out of curiousity, which engine oil was he using? I also wonder if the motor was burning oil prior to this? With only ~2.5 qts and some of these RZR motors burning oil at an accellerated rate mainly due to dirt ingestion (bad intake boots or filter system) it wouldn't take long in some cases for the oil level to reach the bare minimum. It seems like the generally accepted plan is to check your oil level prior to each day's ride, and in Alba Racing's case, to not use Polaris engine oil.
What else can we learn from this besides your comment on maybe poor engine assembly (head shim)?

I don't know what type of engine oil he was using but I can find out from the owner, it didn't show any signs consuming oil that would have been evident in looking at the top of the Pistons and inside the intake and exhaust ports it would have shown evidence of that..
The 11 and 12 models have a dry sump tank and they hold a little more oil than the newer model .
I use Valvoline 10/40 with a Wix oil filter in all the cars I built and never had an issue.
The major cause of this failure was due to torn intake boots sucking in dirt dust and sand

Those torn intake boots could have caused a lean run condition that contributed to this, also. Eh?
Valvoline automotive or powersport for the additives? I switched to Maxima SynBlend 4 10W40, which is what I have used in motorcycles in the past. Napa Gold 1356 (Wix) filter. Just trying to do the right thing for my ride...
