Hi. My brother and I are trying to figure out why his car is blowing white smoke. It does it from a cold start and when revving the car in neutral. I noticed today it smells like raw gas. Can it be from running too rich? I thought that would put out black smoke unless it’s a diesel. I’m getting mixed articles on the subject. If it is too much gas would you automatically check the fuel injectors? Could it be the pump. Thanks for any advice. ---

You don’t say what year the RAV4 is, but on a 2017, a bad fuel pressure regulator can cause white smoke with a gas smell. ![image](https://global.discourse-cdn.com/cartalk/original/3X/9/2/920191e4d006ce965bc9157e3471001ef3b715b3.jpeg) Tester ---

It’s a 2003 ---

If the car is otherwise behaving well, and not consuming fluids other than gasoline, I’d forget it. “Do not go looking for trouble, for you will surely find it”. ---

Stop running the engine. Pull the oil dipstick out. Is the oil level high, and does the oil smell like gas? If so, the fuel injection pressure damper has failed. ![image](https://global.discourse-cdn.com/cartalk/original/3X/b/5/b5d67608b1bdf2d90352abdb453f8bd70058483e.jpeg) Tester ---

> [@Tester](#): > > fuel injection pressure damper It might be a little high. We haven’t really been running the car since changing the fuel. I think it kind of smells like gas. I’m going to ask someone with a better nose to check
