- Worn Piston Rings: Carbon buildup can cause rings to stick, leading to internal consumption. Some owners report success using cleaning products like Valvoline Restore & Protect to unstuck these rings.
- PCV Valve Malfunction: A clogged Positive Crankcase Ventilation (PCV) valve can force oil into the combustion chamber. Replacing this inexpensive part is often the first recommended DIY fix.
- Valve Stem Seals: Worn seals can cause a small puff of blue smoke specifically during a cold startup.
- Valve Cover Gasket: If you smell burning oil but don't see smoke from the tailpipe, oil might be leaking onto the hot exhaust manifold
