Oil filter is tight and seated properly, drain

it sound like to me, you fergot to take the old oil filter seal off. just take the new one off and pull the filter out and take the old seal off before that seal blows off and you really have a problem...but drain your oil first...

Check Front main seal, rear main seal, or one of the EGR hoses. Check oil fill cap. Also check filter if seal was crushed too hard it may be spraying oil out of it. Where is the largest amount of oil? May tell where its starting from.

Check the oil when the engine is cold. Make sure it's at the correct level.

========================
To pinpoint the exact spot. It is best to do a steam cleaning or wipe down the exterior engine before troubleshooting.
========================

The Positive Crack Valve (PCV) is partial blocked.

This is under $10 item. You should change it.

The location of the PCV is on the top (or near top) of the valve cover.

Replace it and the oil/smoke will reciculate back to the correct path (back to the valve cover).
