You're performing a routine service on a Thermo King unit when you spot it: a small, persistent oil leak around the oil level sensor. It's not a major failure, but it's a nagging issue that leads to messy engine bays, potential sensor malfunctions, and the constant worry of low oil levels. This common problem often traces back to a single, frequently overlooked component—a worn or degraded oil level sensor gasket. When this small seal fails, it compromises the entire system's integrity, leading to downtime and unnecessary maintenance costs.
