Experts say drivers should stop driving if they spot exhaust issue | Express.co.uk

If you drive a petrol or diesel car there is one immediate warning sign of engine issues that experts are telling motorists to keep an eye out for. It can be tricky to keep up on all the maintenance for your vehicle but the experts at Bumper say that if you see white smoke coming from your exhaust, you need to get it checked out immediately.

While some exhaust smoke is normal, particularly in cold weather, persistent white smoke in warmer conditions can be a sign of a failing head gasket. This critical engine component seals the combustion chambers and prevents coolant from leaking into the engine. If compromised, it can lead to overheating, loss of power, and costly repairs. If a vehicle emits white smoke in calmer weather, it could be burning coolant.

Ignoring this issue can result in severe engine damage, so it's crucial that you stop driving immediately and find a mechanic to fix the issue

In addition to white exhaust smoke, symptoms of a failing head gasket include overheating, milky or white oil, and a noticeable loss of power.

Any of these indicators should be taken seriously, as continuing to drive with a damaged gasket could lead to total engine failure.

Replacing a head gasket can cost up to £700 - while some sealants may offer a temporary fix, these are not complete repairs and aren't reliable in the long term.

These unexpected costs are why it’s important to make sure you have enough in a savings fund to afford repairs when they spring up.

By acting quickly when spotting the warning signs and planning ahead for potential repair costs, drivers can avoid extensive damage, stay safe on the road, and keep their vehicles running smoothly.
