Engine Smoke Test - Check For Boost Leak | Slough

Engine Smoke Leak Test

from £40

In this test, a special smoke machine is used to send white smoke through your intake system. If there is a leak in your boost / vacuum pipes, the smoke will seep out through it allowing us to find the leak.

This test is beneficial for all cars as there is no other way to check for boost / vacuum leaks.

You can book your Boost Leak Test or Engine smoke Leak Test online under ‘Bookings’

Frequently Asked Questions

What is an engine smoke leak test?

It’s a diagnostic method where safe, visible smoke is introduced into your vehicle’s intake or exhaust system to detect leaks that are otherwise hard to find.

Why is a smoke leak test important?

Boost leaks, vacuum leaks, and exhaust leaks can cause poor performance, rough idling, warning lights, and reduced fuel efficiency. A smoke test pinpoints the issue quickly.

What systems can you test with smoke?

We can test the intake system, intercooler pipes, vacuum hoses, exhaust system, and turbo setup.

Will the test fix the problem?

The smoke test itself doesn’t fix the issue but shows exactly where the leak is, allowing for faster and more accurate repairs.

Do you offer same-day smoke leak testing in Slough?

Yes — we offer same-day diagnostic appointments, subject to availability.

Can a smoke test help with turbo cars?

Absolutely — smoke testing is one of the most effective ways to find boost leaks in turbocharged and supercharged engines.
