Thread: Oil leak defender 300 tdi

Hi all,

i have a question regarding an oil leak i have comming from the rear of the sump, dripping along the back of the bell housing. I am suspecting its the seals of the main bearing.

The question i have is will the leak from the main bearing seals pass through the bell housing and out the wadding plug hole ?

oil is leaking from the wadding plug hole too.

Dont feel like taking the box out for a rear oil seal.

any suggestions appreciated

thanks

Can be a few things


The sump seal as already said. Or the rocker cover seal where it leaks from the rocker cover down the block of the engine and comes out where you see it by the sump

The rear main oil seal almost always comes out of the Wading plug hole on the bell houseing . Cheap part pain the ar*e to fit and expensive

Try putting in that Oil seal refresh into the Oil of the engine, have know that to work on the rear main oil seal . But will only last about 6 months before you have to do it again
