Engine scent free cabs

It seems , to me, that trucks, unlike cars of the same age are engine noisy and have a strong engine smell.   How did they do that in the cars but not in the trucks. That aroma is the main reason my wife does not like to ride in my truck.

I don't know why trucks would be worse than cars, but possibly less attention payed to air sealing.  Clutch/brake pedals?   or airflow around the vehicle with windows down.

 

In any case the major cause of odor is fumes from the road draft tube.   PCV is the answer.  

 

And, be sure the exhaust system is tight and gets those fumes where they can't be sucked into the cab.

Thanks guys, very, very helpful information for novice mechanics like me.  My exhaust system will be very tight from now on.  So much to learn and so little time to learn it.  My leg is healing.

On the noise question, cars often had more sound and vibration dampening under the mats and on the firewall.   Adding that can only help 

 

I'll also be putting that on the roof, underseat, and rear cab wall.  The bottom of the cab got a heavy coat of undercoating when it was off for rust repair..

Another PCV adopter here...crankcase fumes get sucked into charged air and do not waft into the cab that is still missing the original cardboard firewall pad that rotted away years ago.  Truck cabs are noisy if there is not any insulation in the doors, on the headliner, and behind the seat...the hard-to-reach area above the firewall is also a noise transmitter.
