Smoke Testing — Leeds
FIND LEAKS FIRST TIME
Smoke Testing in Leeds
Chasing an air, vacuum or boost leak is one of the most frustrating jobs in motoring — and one of the easiest to throw money at. A smoke test pinpoints the leak quickly and precisely, so the fault is found first time rather than by replacing parts on a guess.
Leeds city driving is brutal on diesel particulate filters and piles carbon onto engines faster than almost anywhere else. We come to your home, office or car park across the LS postcodes — full carbon clean, DPF clear, diagnostics and remapping, no garage needed.
Fully mobile across Leeds and the surrounding West Yorkshire — we come to your home or workplace.
What's Included
Everything a smoke testing covers.
Air, vacuum and boost leaks cause poor running, hesitation, boost loss, rough idling and a string of misleading fault codes — and they're notoriously hard to find by eye because the gaps are often tiny or hidden. A smoke test fills the relevant system with a dense, harmless vapour under gentle pressure, then we watch for where it escapes. That instantly reveals split hoses, perished seals, leaking intake gaskets, cracked intercooler pipes and failing diaphragms. It turns hours of guesswork into a precise, visible result — which means you only pay to fix what's actually broken. We carry it out at your home or workplace as a standalone job or alongside a diagnostic.

Questions
Smoke Testing — FAQs
What exactly is a smoke test?
We introduce a dense, harmless vapour into the intake, vacuum or EVAP system under light pressure and watch for where it escapes. Wherever smoke seeps out is your leak — simple, visible and accurate.
Is the smoke harmful to my engine?
No. It's a non-toxic, residue-free vapour designed specifically for leak testing. It leaves nothing behind in your engine.
Why not just look for the leak?
Because the gaps are often tiny, hidden behind other components, or only open up under pressure. A smoke test makes them visible in minutes instead of hours of guesswork — and saves you replacing good parts.
Can you do it at the same time as diagnostics?
Yes — they work brilliantly together. Diagnostics tells us which system is misbehaving; the smoke test shows us exactly where. We can do both in one visit.
