Difficult, but open up the oil filter and see what metal particles are there and then see what a magnet pulls out to find any iron or steel.
The intercooler is full of metal debris. You need to remove it and clean with hot water and detergent, then back flush with hot, then back flush with a large shop vac. The shop vac needs to be run long enough to get the internals bone dry. If you have a shop vac that allows you to connect to the discharge, that air is warm and will do a better job. However the shop vac hose is dirty and that risks contamination. You may need to limit exposure to harsh caustic cleaners as the IC core is reactive.
Removing the core is a PIA, however, you will have all of the hoses removed. You need to suspend the oil cooler and may need to support the radiator. I have done that work.
Also remove and clean all of the intake pipes and swab the TB with a white paper towel and see what is there. Then open the TB and look into the intake manifold for debris. At that point, the IC passages has limited particle size. Good time to clean the TB, see other posts for that.
Hopefully the oil in the IC has acted like an air filter to pick up particles that are small enough to have otherwise passed through.
Examine the turbine wheel for markings caused by debris.
When you start up, use a cheap basic oil, W40. Run the engine under light loads and get the engine hot. Drain and fill with your normal oil. There will be a lot of metal contamination, particles too small for the filter to have picked up. You need to replace the filter at this time.
Swab in the pockets on the expose valve gallery to look for metal. Would be good to wipe out all that you can.
Be thankful that you do not have a diesel engine. When there is a massive oil leak in a diesel engine turbo/super charger, the engine cannot be turned off and can be damaged by over speed. In the older two stroke Detroit Diesel engines [transit coaches, trucks, generators, earth moving, Marine LAVs, marine etc] there was a stop button that would drop a metal flap inside the intake that would shut of the air flow; which could then be manually reset from the engine bay. I do not know how wide spread that practice is.
