2007 Mega Cab, 105k miles. No oil on ground, but I do see some white smoke that seems to be coming from under the engine when stopped at intersections or when I park in the driveway. Has been too windy here the past month to see where it may be coming from My other half thinks I am crazy, but when we went to change the oil there wasn't but a gallon in the truck that drained out! Talk about surprised! Oil pressure showed NORMAL... even with that small amount of oil in engine. Can't really afford to go to shop & pay for diagnositc (plus since I am female, most shops will try to get over on me). Hoping someone here can help me out. Other than loss of oil & smoke, truck is fantastic.
How many miles since last oil change. Check you coolant and radiator. Also check your exhaust and make sure none is coming out of there. You talked about white smoke. Was it out of left front wheel well. Just some things to think about.
