Very unlikely it's a crankshaft or brg issue. Most likely a leak in the HPO system somewhere.
You can do a air test through the ICP and listen for air leaks.
One thing I would take a look ya first would be the IPR. if you left any debris in the engine from doing the work it will hit the IPR and raise all kinds of issues.
Pull it out and inspect screen for damage and debris. Shop rag lint is a very common problem from wiping down things during the work. If it damaged it enough you can be loosing enough oil go drop even lpop oil.
Another basic question: is the OEM filter cap and Motorcraft filter in it ?
Monitor like ScanGaugeII is priceless about now.
