Hot Rods Smoke rings

Soooo While setting in line for an hour waiting to get into swap meet, I was watching off topic chevy truck directly in front of me. About every 4-5 seconds it would **** out the perfect smoke ring . Very cold this A.M. left side only. Burnt valve? or just a freak thing. Got very bored waiting. but i did find Nashville's HIPPY radio station

 

I think you're still bored. But so am I. So let's talk about cars that blow smoke rings LOL.
I've only seen it happen a couple times. Interesting and notable when it does. One was shooting 10 ft or more. A school bus on a cold morning. Kinda cool. Rich condition, I guess.

 

It happens sometimes. It doesn't mean anything is wrong ... it means everything is just right.

 

Are you Sure you found the Hippy Station after the smoke rings?!

 

It was obviously one of those "reefer" trucks

 

Naw, he was having a flash back to Cheech and Chong and the Van? That started smoking.
I mean an hour in line can mess with a man’s head

 

Afterglow cigarette.

 

I remember a lot of square body C10's doing that. I think it is the last bit of the exhaust tail pipe is straight.

 

Random misfire ....

 

the reason you remember the C10's doing it is because, rounded off camshafts was the culprit

 

Lefthanded Lucky Strike!

 

Exactly. I once had a Dodge six flat head do that. First, tho you need oil smoke in the pipe
( rings ) . Then either fouling plug or leaking valve.

Traveled with a two gallon can of Pep Boys 'Booster' oil, 40wt. The price was one dollar. Needed a fill up every morning.

 

Any round tailpipe will blow rings ... the colder the weather, the more rings. Old engines with dual pipes do it best.

 

"You had yourself a vision"

 

My 64 C10 will pop out the left side only when warming up. If you tap the throttle it will stop. I don't know if it blows smoke rings as the exhaust dumps into the rear tire. Now I will need to look

 

And thats the kind of truck it was!!!

 

I had several. They really were not prepared for the traffic. I tried to remain calm. When I finally got to gate ,lady Says it's full, you will have to go down here ,turn right go next stop turn right and so on. Well as much as I like swap meets i wasn't about to set there for another hour. Went down road and as I got to the end of traffic line, guy opening an old gate, motioned me in. said don't worry about 5 bucks to park, we just trying to get traffic off of I-65 exit.

 

Only time I saw it was when a student put a 440 in a Dart in cl***. Headers (fenderwell IIRC), full length exhaust welded from 2 1/2" pipe and bends up and over the rear end. (Not much room for the second side past the gas tank.)

 

Common in Diesel engines in cold weather with high injection rate fuel systems (P pumps), low compression ratios or worn rings, and low cetane fuel (long ignition delay)
