Burning oil smell or smoke from the engine bay?
Oil leaks are location-specific clues. Valve cover seep is maintenance; rear main or turbo feed line seep needs a different plan.
What drivers usually notice
Symptom language helps us narrow the inspection - not just the stored code.
What gets misdiagnosed
Common assumptions that lead to wasted parts and repeat visits.
- A common misdiagnosis: Location of the leak determines repair scope - valve cover seep ≠ rear main seal.
- Power steering fluid and engine oil are often confused by color alone.
- Adding stop-leak without identifying the source masks consumption problems.

- Monitor oil consumption rate over 500 miles
