Blue Smoke / Engine Compartment Fire on 2014 International 4300 Maxx Force 7

Hi, Folks-
I work for a non-profit that owns a 2014 International 4300 Maxx Force 7.

Last week, a driver reported seeing engine oil spray roof of hood and seep up onto windshield, so we located nearby International dealer and took in. Shop reported it was an issue with the crankcase breather and covered under warranty, so they replaced.

We checked for symptoms at start and close of day for next 3 days without incident.

On Friday of the same week, driver smelled electrical fire, saw blue smoke and then had to extinguish fire in engine compartment once he popped hood. Thankfully, no one was injured and fire was put out.

Oil sprayed all over engine compartment, and down onto ground below truck, where driver also had to extinguish oil fire. Dipstick for engine oil also appeared under pressure, as it was popped nearly 3/4 out of its housing. Fire department shot engine block with infrared thermometer within 10 minutes of incident and it read below 200 degrees F.

My question is, in your folks' experience, could this fire have been related the breather issue or labor involved to fix it that took place 3 days prior to fire occurring? Seems to me that if oil hit the turbo or other elements in compartment that that could cause the fire to kick off?

Truck is en route to International dealer, but I'm hoping for any insight you may have.

Thanks
