Generator exhaust smell in motorhome

I have a Winnebago 37B with a basement air conditioner. The generator in the rear of the motorhome on the opposite side from the air conditioner. I have been experiencing an exhaust smell in the interior. I have recently purchased an exhaust stack to try to solve the problem. It seems to have helped some but I still get the smell. Any one have a simular experience and if so what was the remedy.

First, if it is really exhaust you are sniffing... The CO alarm should be very very annoying, if it is not then one of two common conditions exists.

1: Defective alarm
2: Defective id of smell

You might be smelling "Other engine smells" like hot oil or some such.. Not combustion products.. I do not know.

In any case.. If you can smell it, SOMETHING IS WRONG and needs to be attended to.

BY the way: As I type this I"m sitting here at the shop waiting for things to be attended to on MY motor home. (Different problem but the point is I"m taking my own advice)

Home is where I park it!

I would have the exhaust system of the generator checked. Your's could have a similar problem to mine. Gaskets are cheap, pipes are not, but what is our life worth?

I have the same problem with my recently purchased coach. I think it could be a bad gasket on the exhaust pipes or even a fractured pipe. I won't know until I pull the Onan out for service.

One of the previous owners made the Onan a permanent resident and I have to cut out what they built and then fabricate a new generator slide for mine.

Certainly correct that you need to sort out whether it could cause a danger to occupants of the coach.

Need to consider which way the wind is blowing and realise that due to the many ways such smells can get into a motorhome, the occasional whiff of diesel exhaust is to be expected. Our sense of smell is pretty good so it doesn't take much. However if the smell is even close to being constant or more than slight, you do need to act and until you are sure it is fixed, I wouldn't go to sleep with the generator running. (not that long ago people died in a motorhome because the generator in an adjacent motorhome was running so the danger is real)

Ours will do this if we leave the bathroom or kitchen exaust fans on for a long time creating a low pressure zone inside the coach.

When running the genset while standing still, I usually have one of the vent fans on with air being pushed IN to the coach creating a high pressure zone and eliminating most sources of small leaks from the gen set.
