I woke up to find my engine oil drained, I topped the oil and went to d Mechanic, he discovered where the oil was leaking from(some where under), but here lies my dilemma, he said that the engine will have to be brought down.
I am scared that he will scatter d car for me though he came highly recommended.
To change the main bearing oil seal, does it require bringing down d engine?
Please help a brother. The car is a Toyota Highlander.

There are two main bearing oil seals; one is on the flywheel side and the other at the accessory belt pulley side. Depending on which is leaking, the oil seal at the pulley side is easy to replace without removing the engine whether mounted transversely or longitudinally. The flywheel oil seal is easier replaced on a longitudinally mounted engine (by working underneath) than a transversely mounted engine like yours. Essentially, the transmission has to be removed on an transversly mounted engine, but a longitudinal engine has space to remove the transmission without removing the engine although working undeath a car is not convenient. The transverse engine has no such space to work with both engine a transmission in the engine bay. One or both has to go out for space. It is usually convenient/faster for mechanics to remove both engine and trans at the same time.
