Oil leak on Cat

sudraka · 11-01-2023, 07:01 AM

Hi

I noticed an oil burning smell on my way in to work today, popped the hood when I arrived and found smoke coming from the rear left side of engine. Oil appears to dripping onto the catalytic converter. Anyone know where leak could be coming from ? And what the fix is?

Possibly valve cover gasket. Oil can run down the backside of the valve cover/cylinder head (where they meet), and it will run down the angle of the cylinder head to the back corner and drip down from there onto your catalytic converter
