Lincoln Town Car 1999, Smell of Engine compartment gases (oil/antifreeze) inside the car, whether a/c is 'on' or on 'vent'. My mechanic has already ruled out the Heater Core problem by putting up to 15 lbs pressure, there is no leak of anti-freeze. The smell is more prominent when car is idling. Just before the problem started car was driven on highway about 65 MPH with a/c 'on', a sound of breaking/rupture of some kind of diaphragm was heard, dust particles/vapors came through a/c vent for 2-3 seconds and then stopped. Now all the time smell on engine compartment is noticed 'inside' the car. What is the cause and how to fix it.
Check the exhaust system (even if you cant hear an exhaust leak)

Check your gas cap. If someplace can test it you might luck out. This website advertises manuals and info online. The evaporator cannister is suppose to purify excess fuel vapors. But a system which is not sealed will code an error lamp.
SOURCE: 94 Lincoln TC engine stalls when slowing/stopping
Most common cause of stalling for Lincolns in that era is the TPS (Throttle Position Sensor). It regulates fuel mixture, idle speed etc. A bad TPS will usually act up in one of two ways:
As far as valve cover oil leak, it's a problem that should be addressed to keep oil from fouling your spark plugs but highly unlikely to be the cause of your stalling problem. Hope this answers your question. All the best.

SOURCE: when braking, engine revs up and car moves forward
I have a 1997 Ford Explorer with same exact problem. Even worse, my engine revvs so forcibly, that the truck moved forward and struck another vehicles.
You need to replace the oxygen sensor annually. My mechanic informed me that this problem is inherently prevalent in Fords.
Hopes this helps?

Leaky valve covers burning on your exhaust manifolds leaky heater core or heater lines
