Seriously. Smoke whispering out of the exhaust pipes like a good 'un.
But try the carb cleaner trick for starters. Cheap and easy to do. Watch the video.

Thanks Kilovolt,
Interesting idea using a food smoker for this.
Any danger this could damage the engine?
As for the carb cleaner vid, doesn’t that require a vacuum to work? As I’m guessing the split pipe allows air to be drawn in, so when you spray near the split, it draws the carb cleaner in and that causes the engine to run funny.
With the TDV, doesn’t the turbo pressurise the system, so the carb cleaner would actually be pushed away from the spilt, so wouldn’t be able to cause the engine to run funny as doesn’t get into the air intake system.
I’m guessing here so if you’ve got experience of doing this and it works, apologies for questioning it. But would be interested in seeing it in action!

Did a smoke test on my V8 to find a vacuum leak.
To do so, I used an old paint tin, fitted a tyre valve near the bottom, used a couple of old plumbing fittings to fit a pipe to the lid, pressure was provided by a tyre pump and smoke by a chimney test smoke pellet, worked a treat, found that the dipstick had crack where the bracket was welded on.==================================

Made my own. Paint tin, air compressor fitting, hose connecting to engine. Put some mosquito coils into it and set them on fire. The smoke from the coils found its way into the engine. Fixed two leaks this way.
Similar to the above.

Can you tell me, and this is daft I know, but do you do this with the engine on or off?
And where do you introduce the smoke; via the air intake grill or further down stream, after the MAF sensor?
And is there a risk of damage?
Smoke is particulate after all.

Engine off, I just disconnected the air box and fed the smoke in there. Mine is a petrol but done over 20,000 miles since the smoke test with no issues.==================================

Brilliant, and thanks!
Been watching Eric the car guy vids, and seems a paint can, baby oil (plus or minus dye) and a battery seem a great way to go.
Will see about putting something together

When you consider the soot that goes into the engine from the egr, smoke is no concern.
I looked at my contraption and I made a fitting that goes into the intercooler pipe. This catches leaks from that section forward and pressurises the engine to make the leak easier to detect
