I have an 05 Lexus es330 and I smell burnt oil through my ac and exhaust.. and there is a lil humming sound coming from somewhere from time to time it has 167000 miles and I purchased it about 7 months ago.. I also see oil residue in the front of the engine indicating that there is a leak... What should I do and where should I go.. I live in Atlanta and prices are high for the basics especially car maintenance not wanting to but will spend the some money being that I plan on keeping it for 2yrs then trade ... also I think the previous owner had system and rims because my suspension is unusually high for a Lexus es330 a bit higher than most plus I have these lil black wires coming from under the gear changer
