Car Smells

In most cases is is blown head gasket. The engine suckes air through the hole in the gasket and sends it to cooling system. You never know how long it gonna last.

Can also be caused by a defective pressure relief valve in the coolant reservoir cap. If it is the head gasket, you may also find you can smell combustion gases in the coolant. These won't smell the same as the exhaust gas though as the exhaust has been through the catalytic converter. If changing the cap fails to cure the problem, disconnect and isolate the ht leads or coil low tension wires and remove the pressure cap from the coolant tank. Get someone to turn the engine over on the starter motor while you look into the tank. If you see bubbles emerging in the coolant, it's probably the head gasket.

And a worse case scenario, a cracked head is possible.

Hi, I had the same problem with my car just after I bought it. It's an older model with a carby. I was told because of the heat of the engine it makes it harder to start the car after it has been driven at normal operating temperature. You shouldn't have trouble jump starting it, or just give it a lot of gas when you are starting it after driving. If you have a carburettor, you have to be one with it. Hope this helps

Rubber is actually somewhat porous. A few pounds a year are normal. The number one cause of air loss is usually rim leaks that cannot be seen. Spray soap water solution around the rim to see them. Most tire places will not clean the rim properly when they mount tires and rely on rim sealers that sometimes don't work. On an older car, the rims get rusted in the bead area and need sanding and buffing to seal properly.

It is obvious you have a gas leak. Use your nose to locate the general area of the leak. Once you narrow it down then you just have to search and find what is leaking.

I could be in the shower and I could smell gasoline at work at the mall in my house at all place at all times

Try replacing your Oxygen sensors they are located on the catalytic converter. I had the same problem with my 94 Caprice and that turned out to be the problem.

I think that you may have an oil leak,which is getting on to the front section of the exhaust and whilst travelling along the fumes are being blown away, unlike standing at trafic lights, they are rising up under the bonnet and drifting through the heater/air vents, especially after along motorway run ,I have also had this happen to me!!

I think that we drink to much alcohol and our brains can handle drinking to much.

Clean diesel. No, it's not an oxymoron anymore--it's a term that'll be bandied around frequently as more diesels are introduced. So what exactly is a clean diesel engine?

Clean diesel is a combo: take a diesel engine with advanced CRD fuel delivery and add a diesel particulate filter and selective catalytic reduction exhaust scrubbing technology that takes advantage of the 15 ppm sulfur content of ultra low sulfur diesel (ULSD). Package it all up for a clean diesel that is aimed at meeting increasingly strict diesel emissions legislation.

The pluses: not only do clean diesels offer sparkling emissions, particulate matter (soot) is reduced 95 percent or more (over standard diesels), and there's also a substantial reduction in oxides of nitrogen (NOx) and sulfur. Clean diesels also generate more power and have increased fuel economy since the fuel is burned more efficiently and completely (as compared to conventional diesel engines). The cons: clean diesel engines are compatible only with ULSD fuel and biodiesel/ULSD blends. While widely available, not all stations carry it. Double check that pump label--otherwise only one or two tankfuls of regular diesel fuel can seriously damage the particulate filter.

there are many types of gases but if your thinking of gasoline from a gas station,it probably wouldn't hurt you if you accidentally smelled it or smelled just a bit but if you were intending to smell a lot it might hurt your breathing or make you sick but i don't know if it would kill you or not.if you are thinking of any gas,some gases might harm you greatly or even kill you but it depends on the gas

Check the fuel rail and the top of the gas tank you mite try driving with the gas cap off pressure can do it to

clean it, then spray it with air freshener.

More than likely it is your oxygen sensor/circuit gone bad. Or Clogged, damaged, defective or faulty catalytic converter; Plugged or damaged pcv valve; Damaged or restricted exhaust system components; Restricted, loose or burned out muffler.

Probably valve tappets/lifters/pushrods that have gummed up from dirty or overheated oil. Check the oil level and the color of the oil - when new it is gold colored, and when old it is black and sludgy.

If the engine is old and has not had oil changes at frequent intervals, there are additives available to correct the problem to some extent, ie, to get rid of the gummy sludge. Ask for advice at a reputable automotive store such as Canadian Tire, Napa or PartSource. Once the problem is corrected, be sure to change the engine oil at appropriate intervals.

Could b an O2 sensor OR a Stuck open thermostat or one that's 2 cold-EVEN a clogged muffler or converter-many other things can cause your condition.

You were careful not to get any dirt on the hotwire/resistor in the sensor? I had a dead bug get on mine, and it didn't get burnt off like it was supposed to. This thing is very sensitive, so any debris on the wire will give you problems. You did plug in the IAT sensor, right? There is also a chance that you have the wrong MAF sensor.

Sounds like the psiton rings are shot causing gas to mix with your oil. http://www.autozone.com/servlet/UiBroker?UseCase=S001&UserAction=viewSimpleDiagInfo&Parameters=info

There are usually no more than 3 hoses coming from the tank: # The fill hose connects the fill neck to the tank # The vapor recovery line. This comes off the highest point of the tank and takes fumes to the charcoal cannister. # The fuel line. This, on a car that doesn't have an in-tank fuel pump, is not under pressure but will continue to siphon fuel from the tank if it leaks. If you are only smelling fumes and not seeing leakage, it is reasonable to guess that it is your vapor return line.
