Since you do have exhaust smell in your cabin,I suggest to check the rubber sealer at the rear boot door. As the exhaust end is at the rear boot door side, it is the only place which allow the smell to get in the cabin,since the rubber sealer is either broken,cracked or softened and do not seal well the boot.

SOURCE: I have a strong exhaust smell- a put-put noise

most likely (since it is not the muffler) is the donut where the ezhaust pipe hooks onto the exaust manifold....or the manifold cracked or needing a new gasket

SOURCE: exhaust smell in cabin of 2001 dodge ram

Is it exhaust or is it a fuel smell? Exhaust, i would say you almost have to have a leak, check the manifolds and the head pipe really well. Check to see if ti even has an EGR valve at the rear of the intake to the top of the intake manifold, it depends on the emissions label it has under the hood, federal or california. If it is more of a fuel smell check to be sure all of the charcole canister lines and hoses are hooked up and not gone or broken.

SOURCE: Cabin smells when heat or defroster is on

What your smelling is most likely coolant (antifreeze). You may have a heater core leak. If you dont smell the same smell after running the A/C or just vented cool air from outside for a few minutes then that is your problem.

SOURCE: how do i fix an exhaust leak where vthe exhaust

It depends what is causing the leak. If there is a hole in the pipe, you may be able to cut the pipe and install a coupler with a couple of clamps. If the hole is at the point where the pipe is welded to the muffler, then you have to cut out the muffler and replace it.

I smell gas in the cabin of my 2008 chevy impala, it has 70,000 miles ... the smell wont go away any answers??


smell gas in the cabin Kenny, Fuel line is probably leaking, would have checked immediately by a qualified tech. This could be extremely dangerous if fuel is spraying/leaking on hot surface such as exhaust.

Hello , there is a low humming sound when I turn my car on or when I accelerate and when i turn my car off there is a ticking sound what could this be?


Well an exhaust leak is not usually a hum, more like a rumble.
You should be able to listen under the car while someone is revving up the engine and hear an exhaust leak.
The ticking sound is normal for metal that is very hot and cooling off.
The burning smell could be oil leaking onto the exhaust manifold or pipe.

I just fixed my flex pip on my hyundai accent now I have a loud exhaust noise my check engine light is on saying I have an oxygen leak but took it to a mechanic in they told me that I don't have a exhaust...


Take it to a muffler shop-that mechanic must have a tin ear. I thought my Sentra had a small exhaust leak (slightly loud exhaust noise) from a previously fixed exhaust connection. But a muffler shop guy showed me I had a rusted out catalytic converter. I would suspect your flex pipe may still be leaking.

I smell exaust and my accord is also buring oil


if engine is running bad, there is huge lethal Carbon Monoxide
present in exhaust, so keep this beast outside, and not park
in any snow banks.
and keep the non recirc, fan on , while in car. as a precaution.

now find a muffler shop and tell him/her, fix my exhaust holes.

adding oil . ./ is normal for all cars. faster you drive the more oil.
how much oil,? 1qt/3000 miles is ok, 1qt in 1000 is a ver tired/old engine.

on old cars, check oil every fill up. until you learn your rate of consumption..

2001 Subaru Outback has super strong exhaust smell coming into the cabin. I also see a small hole in the muffler. Could the hole be causing exhaust to come in through the vents or is it something else...


Its possible, but usually what you smell inside the cabin is coming in thru the fresh air intake in front of the windshield. The source is usually in the engine compartment.

Smell cabin


A modern, well maintained vehicle's exhaust is virtually orderless once the catalytic converter has fired up. What you could smelling is oil leaking from the engine, for instance, from the valve cover that then drips down onto the hot exhaust where it vaporizes. That oil vapor is then ingesting into the passenger compartment through the fresh air intakes. Try airing out the cabin and then set the ventilation controls to recirculation mode to see if the problem persists. Also, the oil vapor will only happen when the exhaust is hot. So if you don't smell it when you first start the engine, that could be confirming this cause. Look at your engine and see if you see oil and dirt oozing from the valve cover gasket. You can try to tighten the oil cover fasterners to see if it stops the leak, but the best approach would be to replace the valve cover gasket.

Like motor cycle noise near muffler area


This kind of noise usually indicates an opened area in the exhaust system. You can find the trouble spot by looking at your exhaust system from front to back. You will see a darkened area around any exhaust leak that looks like ash. If this is the case take the car to a reputable muffler shop and get it fixed, you are probably due for a new muffler. GOOD LUCK.
