Could be burnt oil smell. My Rav gives a little puff of blue smoke sometimes when first starting in the morning which mechanic tells me is a slight valve seal leak. I just put in MaxLife High Mileage 5W30 engine oil which is said to condition seal rubbers after using for a few weeks so that may help the problem.Every time i start my engine, there is a smell of gas near/around the exhaust.
Its a 5 door Rav 4 - XA20 year 2003.
What might be causing the gas smell ?
