Oil leaks can usually result either from a failure of the static seals, i.e. the gaskets, or the oil seal, or from the failure of one or more components. It is therefore important to understand if the damage only concerns the seals or if it is more widespread and involves the pump or the whole engine. In fact, in the first case, to solve the problem it will be sufficient to replace the damaged seal or oil seal, while in the second case it may be necessary to replace the entire pump or motor.
