It’s easy to assume that engine oil leaks will be more prevalent when the engine is running. When an engine is running, oil pressure increases, which makes it more likely that engine oil will leak. Quite often, however, we can see engine oil leaks that occur when a vehicle is parked and the engine is cold. Here’s why.
When your engine is hot, the block, head and other metallic components expand. This expansion can force components closer, squeeze gaskets and seals tighter and create a seal that effectively prevents oil from leaking. When you turn off your engine and it starts to cool down, the metals contract, which can open gaps between seals and mating components. The result is a leak that only occurs when the engine is cold. Fun? Not really.
This kind of leak needs to be repaired. All leaks will eventually get worse, and if it happens when you’re driving, you risk breaking down and causing major engine damage. Oil is an engine’s lifeblood – your engine needs the right amount of oil for lubrication and cooling, so even a small oil leak can lead to big problems.
