Hi all, Every car I have ever owned (except a commodore) has had a leaking rear main seal. Some of my cars worse than others. I have a rebuilt 5mge in one of my cars, and it started leaking straight away after the rebuild. From previous research I have herd that rear main seals can leak because of improper fitment, crap seals (crappy brands that come with clutch kits), and also due to crank balancing. Crank balancing is the one that interests me. I want to repair the leak on one of my 4x4's, because it's leaking oil really bad, but to go to the effort to remove the gearbox and replace it, and have it continue to leak after replacing it makes me wonder. If my crank hasn't been balanced properly, is there any way to make the leak stop? Or does anyone have installation tips? because I know for cam seals some people have tricks for installing them like using a punch on the edges to try and expand the seal. Cheers
