Hi There, I'm Clay a certified master automobile technician with 30 years of automotive repair and diagnostic experience.

From your description most likely the Positive Crankcase Ventilation (PCV) is sucking oil into the intake. With engine idling, check for excessive crankcase vacuum or pressure on dipstick tube or at oil filler cap. If oil level is correct, inspect PCV breather hoses and connections on cylinder head to verify no collapsed or blocked hoses. Remove the upper PCV covers that are on top of the valve covers. Inspect for blocked passages. Remove valve covers and inspect for sludge restriction in Positive Crankcase Valve (PCV) breather baffle in valve cover. Clean the valve cover. You should also remove the spark plugs and make sure they are not oil fouled, replace as necessary. Bosch...... DPER or DPP332 Plug gap 0.8mm

I hope this information is helpful. If you have any questions or run into any problems let me know.

Kindly rate my assistance in a positive manner so I may have credit for helping you.
Positive ratings are greatly appreciated.
Thanks.
