Smoke started coming out of hood when returning home. Opened hood to check engine and choked on smoke. After engine cooled, found VVT-I tube is leaking at lower end of rubber hose. Engine oil had accumulated around engine compartment aft, a bit foward of VVT-i tube, and to passenger side. Searched Internet and saw that LSC-90K oil line "campaign" has the exact same part that is part of campaign that failed on my engine, but my VIN is not part of campaign.
