If it is a burning oil smell, it is typically a leaking valve gasket cover and is leaking down onto the exhaust pipe. Are you losing oil? Also, check the oil filter housing as well. Could be leaking from it where it connects to the engine (the gasket could be be broken). Worse case scenario is a head gasket leak which would be further down in the engine block but harder to see in a tight space. Need to get a little telescopic mirror. If you are smelling it, it is leaking and burning on the pipe, somewhere.
