When a technician is checking for engine oil leaks, an often overlooked procedure is checking the crankshaft seal. The crankshaft seal is located at the front or rear of the engine and prevents oil from leaking out around the crankshaft. If the seal is worn or damaged, it can lead to oil leaks.
Another important procedure that is sometimes overlooked is checking the valve cover gasket. The valve cover gasket seals the gap between the valve cover and the cylinder head, preventing oil from leaking out. If this gasket is old or damaged, it can cause oil leaks.
Additionally, checking crankcase pressure is crucial. Excessive crankcase pressure can lead to oil leaks as it can push oil past seals and gaskets. By monitoring crankcase pressure, technicians can detect issues that may cause oil leaks and address them promptly.
In summary, when checking for engine oil leaks, technicians should ensure to examine the crankshaft seal, valve cover gasket, and crankcase pressure to identify and prevent potential leaks.
