Q: Just found out that my vehicle has been leaking oil for at least 2 yrs. Would smelling that burning oil smell cause health issues?

asked by on February 27, 2017

My Toyota Tundra had three separate oil leaks all under 30000 miles. Nine times out of ten when I drive the truck I smell a horrible burning oil smell. I have also noticed that when the dealership did the undercoating that they sprayed everything. They sprayed parts of the exhaust, heat shields, manifold and even near the engine and parts of the engine. On some occasions I have even seen smoke coming out from under my hood. My truck always smells like burning oil to the point I have to put the windows down to breathe. My question is can those oil leaks, the burning oil on the engine and inhaling those fumes for 2 years be the cause of my health issues, which I have had lately. Also, can that undercoating smell or fumes when it heats up and/or burns off cause health problems as well?

Thank you for your time, Larry A.
