Customer told manifold was blocked. After our inspection, it wasn’t. Get honest diagnostics at 1Stop Motor Shop in Newtownabbey & Belfast — no guesswork.
At 1Stop Motor Shop, we don’t just take someone else’s word for it — we diagnose every issue ourselves. A recent customer left their vehicle in after being told by another garage that the manifold was blocked.
After stripping down and inspecting the intake system, it was clear what was really going on.
It’s easy for blocked manifolds to be wrongly blamed for symptoms like:
Poor acceleration
Rough idling
Loss of power
Excessive smoke or emissions
But in this case, after removing the manifold and inspecting it internally, we found it was not blocked at all — just carbon build-up that didn’t warrant full replacement.
Some common causes of manifold issues include:
Carbon deposits from EGR systems
Oil mist and soot from crankcase ventilation
Faulty EGR valves or blocked DPF systems
General engine age and lack of servicing
But before replacing major parts, we always carry out a full inspection to confirm the actual cause — saving our customers time and money.
At 1Stop Motor Shop, we take pride in: ✔️ Transparent diagnostics
✔️ No unnecessary part replacements
✔️ Customer-first service
