If it were me.
first is the borescope to see if the #3 piston is holed, if yes, the motor comes out for inspection likely new motor, if no-
Pull the Filter and oil pan - if there are metal chips in there and they are magnetic, look to the IMSB next, and there are plenty of thread on THAT in this forum
If no metal , pull the cam cover and look for a broken valve spring.
If no broken valve spring, dump the head and look for a bent valve indicating a valve timing issue possibly IMS- .
For the head I take the engine out of the car for clearance.
Best of luck! I hope its a valve spring!
