Not sure what you mean? Do you mean the oil is leaking out of the rubber "Boot" that goes over the final drive take off at the rear of the engine. ( close to your right foot). If oil is coming out of there then the oil seal on the final drive shaft on the engine is leaking. Its an engine out job to fix this???
Is it at the engine end, oil leaking into the boot at the back of the engine? There is a seal at the back of the engine, you can replace them after first pulling the universal joint off the output shaft.
