...is a great way to discover the severity of a leaky exhaust manifold
That is all.

Funny you say this. I actually almost bought some just to test for exhaust leaks!

In reply to Taiden:
Yep, after todays episode, I'd say that's a pretty good way to do it!

Neat! I'll have to use this in the future. Did you notice any change in vehicle operation after the Seafoam treatment? I have always wanted to do a compression test before, and after Seafoam.

Just how thick was the smoke? I've held off on doing this for fear of the neighbors calling the fire dept, as the property butts up against the side of a heavily wooded large hill. Is the color of the smoke white, too?

I had a buch of neighbours come out when I did my truck at our old house. They all thought I had caught my truck on fire
Lots of white smoke that hung around longer than I would have expected. Do it on a windy day.

how much smoke depends a lot on the engine... i've done it on cars with very little smoke and others that it feels like you're standing on a stage with a dozen smoke machines...

Gonna do it today on two cars at the same time, in the middle of a hot day.....down at the beach, ya'know, for the wind. And it's more than a bit secluded. I remember my parents mechanics doing the same with straight kerosene. Yup, lots of white smoke.

As I was writing the post, that thought came to mind, that someplace I had heard the same. Never did it, though.

The vehicle was my 2000 Silverado 6.0 LQ4. I had already changed plugs and wires, and checked for vacuum leaks, and I still had a slight shake at idle that irritated me. After the Seafoam treatment, it idles absolutely dead smooth! The smoke was, well, let's say SIGNIFICANT. An lasted longer than I anticipated. There was a pretty good breeze here yesterday, and that helped. I think I won't do it in my driveway next time...

I did it on my 2.5RS. The smoke was opaque white and as mentioned, if there's no wind it'll hang in-place for an amazing amount of time before dissipating;
e.g. http://www.youtube.com/watch?v=coZVpNdJfkw&feature=related
It fouled the oxygen sensor for a day or two as well triggering a SES light...

Do it in the countryside, on a dark night.
No, it's not the most fun thing one can do in a car in the boonies at night, but it will get the job done.
