Smoke (blue or black) or steam (white)? White smoke is really steam that is caused by water leaking onto hot surface. Could be leaking from hose running to heater coil under dash, or something else. Check radiator water level to make sure water level is ok. Blue smoke is oil burning. This could be dangerous, caused by similar scenario of oil leaking on a hot surface (from a gasket leak, etc), or exhaust fumes. Black smoke means something is actually burning and could indicate fire. Black or blue some could fill vehicle cabin with toxic fumes, even if you don't smell anything bad.
A Carbon Monoxide tester for homes may be used inside your vehicle. This will verify your concerns about the fumes inside your vehicle.
If you hear something while the engine is running, you may have an exhaust leak. This is something a Muffler shop can check. I don't know about recommending a business as I probably do not live in your area.
Our site use to have affiliations with Repair shops and if you can go to an Online Expert's Repair shop you should get an honest repair.
Word of mouth advertising should get you to a good place. For an exhaust smell, since carbon monoxide is odorless, a sulfur smell would indicate problems in the Catalytic converter area. Or if your vehicle is burning a little oil, there would be a detectable odor.
Wish I could say it is an exhaust tube or O2 fitting leaking and solve your problem. Best I can say is protect yourself with a Carbon monoxide detector and have your vehicle visibly checked.
WHERE IS THE LEAK LOCATED ON TOP OR BOTTOM ? CLEAN OF THE OIL THATS THERE AND TURN ON CAR AND DRIVE IT IF U HAVE 2 NOT FAR BUT CLOSE AND CHECK WHERE THE OIL IS COMEING FROM IT COLD BE YOUR VALVE COVER GASKET
If its the 3.1 or 3.4 they almost always leak under the intake where the intake touches the engine block..Sometimes they even leak internally and could get in your oil..You really need to pressurized the cooling sytem to know exactly wheres its coming from..Sometimes if leaks are small they can hit hot parts of the engine and burn off before you can catch it..So if you use a pressure checker youll be able to find it..I would try autozone they have some tools you can rent for free just leave a deposit
Yes your in the right area, it should be up under passenger side behind housing etc., where blower motor is located. If you haven't noticed coolant return bottle level going down then I would have the cooling system pressure tested to see if it drops, indicating a leak somewhere. Also check all your hoses and connections especially near firewall where they go in to vehicle, in case there is a small leak at fitting or hose and the fumes from it are being drawn in through fresh air intake under cowl at base of windshield. It might just be an external leak, and fumes are being drawn into cab.
From where? you haven't given enough info, but put a large piece of flattened cardboard under the car to see if any is leaking. You will then be able to see what general area it's coming from--if there is a leak.
It could be a fuel injector(s) or even something very simple. When is the last time you had a tune-up, including a new fuel filter? If it's been more than two years, it's overdue. That means new oil, oil filter, air filter, fuel filter, and spark plugs.If your car has a distributor, you should also replace the distributor cap and rotor (cap).
Try to locate a specific area where the smell is coming from. Breathing gas fumes is not healthy!
Check the front passenger side carpet and make sure it is dry. If it is wet, the heater core up under the dash is leaking, which is why you smell it in the cab.
There is a chance you may have an engine bay coolant leak and the fumes are being drawn in through the heater ductwork so verify that first. But.... Coolant fumes inside usually come from a leaking heater core. The heater core is like a small radiator inside your vehicle that gives off heat. Problems like this arise from coolant that has not been flushed and creates an electrolysis that eats away at the material causing a leak. This is not a job for a do it yourself guy(or girl). A pro could easily spend 5 to 7 hours changing this one. Make sure whoever does this repair flushes the system.
possible valve cover leaking,at least this is more likely the cause, they make a die that you can use too help determine where it is leaking but some dies require ablack light too see the die,
neither one of these would cause gas to leak. sure it is not coolant ? if you think it is gas it is not safe to drive car as it could catch on fire. possible cause would be a leaking injector.
