Hi people,

 

Everytime I put on the Ac (or heater), for few minutes, there is a distinct smell of exhaust fume in the car

 

I know the distinct smell because my car is running a bit rich so slight smell of petrol mixed with fumes.

 

Although I recently re-build my motor with new wiring loom, and have check for leakage on the joins in the exhaust system - I doubt if this could be the problem - but then I don't know so that is why stating all the facts here.

 

Also few years ago, I changed my heater metrix and did noticed then that whenever AC/heater was used, we all have sore-throat (the family I mean) but then I took car to Nissan to clean the ac system.

 

I have restraint from using Ac/heater but there time when I just had to switch on and the result is alway the say.

 

Have anyone have an idea of what might be causing this problem.

 

Thanks

Same kinda thing i get a gassy smell from mine sometimes, any ideas ?

I used to get this in a supra and it turned out to be a BHG im affraid as exhaust gasses where getting into the water and whenever used the heater is smelt quite bad, check the rad cap and see if there is and emulsfied oil on the rad cap. also is the an oily film over the water? :bow:

 

Im not the best technical bod in the world so i could well be wrong.

mine aint anything to do with that

Like i said not the best technical bod so could be something much more simple, :bow:

Fuel leaks in the engine bay?

 

Mine does this as well.

yep leaking fuel lines will deffinatly cause the fuel smell from the vents, not so sure on the exhaust fumes though, sounds a bit iffy.

Look here mate-knew I saw it somwhere! :wack:
