Factors influencing the feasibility include:
* Vehicle make and model: Some vehicles have more accessible oil pans than others.
* Engine type and design: The engine's design significantly impacts accessibility.
* Available tools: Specialized tools like shallow sockets, swivel sockets, and extensions are often necessary. A drain plug wrench that can easily work in tight spaces is essential. You might even need a flexible ratchet or similar tool.
Significant drawbacks to doing this in-situ:
* Increased risk of damage: The close quarters increase the risk of scratching or damaging surrounding components.
* Time-consuming: It'll take considerably longer.
* Frustrating: Access is severely limited, leading to frustration and potential mistakes.
* Difficult cleanup: Spilled oil is much harder to clean up when working under the vehicle with limited space.
While possible, it's generally recommended to remove the engine or at least lower it as much as possible for easier oil pan access. Unless you have significant experience, the extra difficulty and risk probably outweigh any perceived benefit of keeping the engine in place.
