Regular inspection of the O-Ring 18*25*5 during a top-end overhaul is essential. A worn seal can lead to pressure loss and contamination of critical engine fluids.
A failing seal usually manifests as external oil sweating or coolant leakage around the joint area. If you notice a drop in pressure or visible fluid accumulation near the housing, it is time to inspect the 18255 seal. Ignoring this can lead to overheating or component friction damage.
