1995 seville has some smoking at rear of motor, is this serious
what could be leaking at rear of motor next to firewall to cause small amount of smoke when running?
An oil leak dripping on to the exhaust, Better have that looked at, if it got bad, there is a risk of fire. Motor oil is not as flammable as , say auto tranny fluid but heated enough will burn. Ordinarily a small oil leak is nothing to be concerned with, but smoke indicates what I mean by it's getting on exhaust
First thing I can think of is a leaking valve cover dripping oil on a hot exhaust pipe. Second thing would be a leaking heater hose. What does it smell like. The liquids have a completely different smell.
