The timing chain keeps the top and bottom of the engine in sync, so the valves open and close at the right moment against the pistons. Over time the chain stretches and the tensioner and guides wear, and that is when problems start. We replace the chain and the parts that wear with it on cars and vans of all makes.
The classic warning sign is a rattle on a cold start that settles after a few seconds. You might also notice misfires, rough running, hard starting, the engine light coming on, or metal flakes in the oil. None of these are worth ignoring, because a chain that snaps can wreck the engine.
We inspect and diagnose before anything else, so you know what you are dealing with. Then we replace the chain along with the guides and tensioners, change the oil and filter if needed, and test the engine before the car goes back to you. Catching it early is far cheaper than a new engine.
A timing chain job is bigger than a quick fix, but most take about a day depending on the vehicle. We will confirm the timing once we have seen the car. You get a free, clear quote before any work starts, with no surprises added on later.
Because we do bodywork and mechanical under one roof in Tottenham Hale, anything else we spot during the job can be sorted in the same place. We are open every day from 08:00 to 22:00, with same-day availability on many jobs, so you are not waiting around for an appointment.
We are at 59 Garman Rd, easy to reach from Seven Sisters, Stoke Newington, Wood Green and Edmonton. If you have heard a rattle on startup, call us or message on WhatsApp and we will tell you what to do next.
What a timing chain does
Your timing chain keeps the camshaft and crankshaft in sync, so the valves open and close at the right moment. A worn chain that is left can cause serious engine damage.

Good to know
How long does it take?+
Most timing chain replacements take about a day, depending on the vehicle. We always aim to get you back on the road as quickly as we safely can.
How do I know if it is the chain?+
A rattle on startup, misfires or metal flakes in the oil are common signs. Bring it in and we will diagnose it before any work starts.
What happens if I keep driving with a worn timing chain?+
It is a real risk. A worn chain can stretch, skip or snap, and on many engines that lets the valves and pistons hit each other, which causes serious and expensive damage. What starts as a cheap chain replacement can turn into a new engine. If you hear a rattle on startup, get it checked before driving the car much further.
Why not just replace the chain on its own?+
Because the parts around it wear at the same time. We replace the guides and tensioners along with the chain, and change the oil and filter if needed, so the job is done properly and you are not back again soon for a related fault. We test the engine before the car leaves. Most timing chain jobs take about a day depending on the vehicle.
We also offer brake repair, diagnostics and full car servicing in Tottenham Hale, Stoke Newington, Seven Sisters and across North London.
