How do I know if my lawnmower has a blown head gasket?
If the mower is dropping out or not starting and you do notice the oil leak, you have a bad gasket. If the mower shuts off when you turn corners, but there is no oil leak, you may still have a bad gasket since the pressure to keep the combustion going is not strong enough.
Can you run with a blown head gasket?
But there’s a more urgent issue to be aware of if you’re driving with a blown head gasket: if the coolant is leaking, then it’s no longer available to cool down the engine. Without this support, the engine will soon overheat if you keep driving – leading to further cracking and damage to your engine.
What are the first signs of a blown head gasket?
Bad head gasket symptoms

How do you know if your lawnmower is blown?
Here are a few signs that your lawn mower’s engine or head gasket is blown:
- There’s an oil leak.
- There’s smoke coming from the exhaust.
- The mower has low power and pressure.
- Your mower fails a compression test, or there’s diminished compression.
What does blown head gasket sound like?
If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. This loss of compression results in a rough running engine and a notable reduction in engine power. This sort of failure typically is accompanied by a sound like an exhaust leak.
What does it mean when a lawn mower blows white smoke?
White smoke indicates that the engine is burning oil. This is usually due to a spill or accidental overfilling of the crankcase. As soon as the trace oil that has reached the engine is burned off, the smoke should clear up and your mower will operate fine.

What happens when head gasket goes?
If the head gasket is damaged, the engine will quickly overheat and serious damage will be caused. Overheating in the engine of your car will lead to a loss of compression, the mixing of oil, water, coolant as well as a reduction in lubrication.
