I have my old chevy daily driver now for 11 years and can't believe in what condition I used to drive it.
I had leaky bypass oil canisters and carbs drip on the exhaust pipe and engine block for many years. Never enough to cause even smoke.
Finally starting in 2002 I learned from forums like this how to fix, tune and rod my engine.

Have personally witnessed 1 engine fire in my entire life.
Real life seems nothing like the movies where a bullet, a cigarette or a crash causes massive explosions.
It's more like this crazy guy I knew who drove a poorly built high performance 350 which needed 3 quarts of oil and 10 gal of fuel every 10 miles.
Leaking and smoking like hell - amazingly he never turned into a speeding fireball, making the news.
