oil leak , rear engine seal??

[TheKoose]

Hey guys

Got another issue on the project. Oil is leaking from the drain hole where the gearbox meets the adaptor plate/ engine? Is this common or could it be due to the fact ive just found out its got far too much oil in it?

It is usually the sump gasket, you can remove that small cover plate and check to see if there are any breaks in the seal. Thats where mine was leaking noticed after I'd changed the crankshaft seal when I thought that was my problem .

Do a search for sump gasket and you will find the answers you need

As above. Ten faulty sump gaskets to one faulty oil seal.
Changing the sump gasket is not an easy job on a 6 pot though!

SHouldve bloody guessed knowing my luck.

Cheers for the tips guys.

It's easier than the bloody crankshaft oil seal.

Not to me, crankshaft is a piece of piss if its the same as 318. Drop the box, fly and clutch change seal and refit. Not hire engine crane hoist engine, drop the bloody subframe etc etc!!

On the 325i the gearbox bolts are a pain to get to very tight in there and the box is heavy. To do the sump you don't need a hoist and you don't remove the subframe you just undo the 2 nuts for the PAS rack push it out the way undo all the bolts on the sump undo engine mounts and jack up the gearbox bell housing end reach in drop oil pump pick up and out she comes.

Ahhh i see, shouldve known better to assume things aboiut a car ive never done it on. How come i need to drop the pick up?

[Brianmoooore]

You don't need to remove the oil pick up (and I recommend you don't) if you undo the engine mounts and lift the engine as high as it will go.
Might have to slacken off the four subframe bolts as well to loser that a little.

My god, all for a sump gasket. Thanks for the help guys.

Here's a link that might help, http://ee1394.com/bmw/docs/factory/repair/en/index1.htm

Why would you not recommend removing the oil pick up? That's what I did and as far as I'm aware its the BMW method. Does it cause problems?
