0104142018-11-13. Service bulletin. ENGINE AND ENGINE COOLING. External Engine Oil Leaks and Repairs. During the vehicle's operational life, normal engine oil seepage or sweating, in addition to accumulated road dust, dirt and grime in the engine compartment can cause the appearance of a more severe oil leak. This is further exaggerated by residual oil that remains on the engine assembly after maintenance services are performed, e.g., oil filter changes, "engine oil top-offs," etc. If this visual appearance of accumulated oil on the engine assembly as an "active leak" is misinterpreted, unnecessary gasket repairs/replacements will result. Specifically, our analysis of the claim-related data for vehicles equipped with the engines noted in this bulletin is showing an above-average number of engine gasket repair/replacement claim submissions. The purpose of this bulletin is to provide your workshop with information and a procedure that will help in identifying engine oils leaks that do and do not require a repair.
