Crazy zany question or Incredible invention?

[Runnah]

Is there any type of additive you can add to your gas tank to turn the smoke a color so you can find exhaust leaks?

Not that mine is leaking...Im asking fo a friend.

For a really cool yellow smoke just add nitro-methane.

A little late, but have someone hold the throttle plate open and spray carb cleaner into the intake while it's running. Plenty of smoke (all white though).

add oil, it'll be bluish white ;D

+1 on Seafoam. It'll do good to the engine plus you'll get a smoke show
