I have a 95 nissan quest. When the engine is started there is a smell of exhaust inside the cabin area. The smell is coming through the vents. When the van is moving and the heater is turned on the smell is really strong. How can I solve this problem?
The exhaust leak is almost always broken studs on the exhaust manifolds. It makes a tick noise when cold and usually goes away when the engine warms up. After a year or so, the noise doesn't go away.
Your heater-a/c air intake is at the base of the windshield through the screen on the passenger side. WHen the exhaust leaks from the manifold, the exhaust gas gets sucked into the air intake.
You can put the heater in recirc mode and it will draw air in from inside the car instead of though the outside air intake. You can't leave it in recirc for long in winter or your car will get ice or fogging on the windows from too much humidity. Take it off recirc after 10 minutes.

Do you have an audible exhaust leak? These engines were known to have exhaust leaks.
