Message-ID: <[EMAIL PROTECTED]>
Noticed that my 95 E36 (~120k) started dripping motor
oil on the garage floor the other day, it wasn't much
at all, I'd say ~1 table spoon/12hours. Went under
with a flashlight and found that it's coming from the
oil drain plug, so I just loosened the plug (which was
still kind of tight) and re-tightened it again, and I
think that might have stopped it (hopefully for good.)
I'm using synthetic and I change all washers at every
oil change. any idea of why there is a leak there?
seems like an odd place to be leaking.
thanks,
Paul

I always make it a practise to clean up this area really well after draining
the oil & replacing the plug. What happens is you get oil in the threads &
behind the washer squeezed out.
Also, this little lump in the oil pan on an S14 is the lowest point. My car
actually has seeping pan gaskets, but the oil is dripping off here. Make
sure your leak isn't coming from somewhere else.

My apologies to the list.
Sorry, I don't always have time to read all the posts when I am away on
business. I was catching up on old posts when I see that back on the 15th
or so Brett replied to a similar question with "Autologic". Thanks for the
site as well Brett, looks like they have some good specialty tools and info.
I will pass it on to my brother.

Steve, it would help if you told everyone that you were driving your E39
540i Sport. You're welcome. I was announcing when Steve ran. I had to
point out that the smoke out the back was not from the flames on the side
of the car - those are magnetic. Someone suggested that the smoke belch
was just from your cigar. :^)

The Bentley manual says to replace the nuts. I got mine at Orchard Supply.
Yes, they have metric locking nuts. The Bentley manual does not say to
replace the flange, so I didn't.

Tricks? I never needed tricks for this. The drive shaft has splines
between the front and back halves. Push the rear of the drive shaft
forward, and the splines should slip to allow the forward movement. The
dark blue-green diff oil color is not uncommon. You've already done the
hard part!

Mitchell and Brett,
Thanks Gents.
Good to know Amsoil was used in this diff.
Brett, your info prompts the next question. I did plan to replace the input
shaft seal which would intail removing the flange. So your input implies
re-using the flange and nut and according to Bentley retorqueing to
300ft/lbs (from memory). Could the input flange have a groove worn into it
as if possible with the output flanges? If so, what do you do then? New
diff?
Is it better to just change the output seals and leave the DS seal alone?

If Bentley says 300ft/lb, they're WRONG. That is also a spec published,
erroneously, by BMW. You will lose your pinion bearings if you do that.
The nut and end of the pinion have a paint splotch. The theory is that you put
the nut back on and keep turning until you line up the paint mark, but the paint
mark usually gets all beat up during removal. Use a magic marker or hammer and
chisel to mark the nut to the pinion, before removing.
If flange has a seal groove cut into it, countersink the seal to give it a fresh
surface to run on, there's a fair amount of available room for this.

Subject: <e34> ATF change - how can I get all the fluid
Message-ID: <[EMAIL PROTECTED]>
I need to change the automatic transmission fluid in
my 1993 525i. I have the new seal and filter ready,
but I haven't been able to locate a procedure for a
"complete" fluid change. Bentley is just a basic
drain and refill, but I would like to drain and
replace *all* the fluid in the system at once -
including torque converter, cooler, and transmission.
The alternative is a dilution approach removing the
easily drain-able portion driving and repeating the
process - as outlined by Neil D. on his (now
nonexistent??) web site.
Any hints on a complete ATF change?
John

As I have never seen an E34 automatic transmission, I am going to guess
here, but how about a compressed air supply into the return line on the
filter housing (if there is a "filter housing"). It might be messy, but it
might also blow the old fluid through and out of the transmission.

It can be done. It's called a full rebuild.
There is no other way to get the other half of the fluid out.

You can do pretty well by 1) dropping the pan and changing fluid &
filter as planned. and 2) flushing the remaining old fluid out through
the oil cooler lines.
I can't be sure of the e34 unit, but in most autos, the fluid leaves
the torque converter, goes through the cooler, and returns to the pan.
If you direct the cooler lines into a bucket, you can start the engine
and add fresh fluid to the filler neck while old fluid squirts out.
Once fresh fluid is coming out of the cooler line, you're as done as you
can get. The remainder of the old fluid that's still trapped in the
various clutch packs is not much compared to what you just pumped out of
the torque converter.
I last did this technique on my e39 and it worked fine. Though I had
to force new fluid in via the return line because there ain't no
dipstick/filler tube!

I have plenty of experience with GT-1. I like it, but at $17,500 it's
expensive. Couple this with the fact that as of end of this year, it's not
going to support programming or coding, and it's VERY expensive.
I have no experience with Autologic yet. Will be in Atlanta Wednesday through
Sunday of this week at an OSS meeting and we will be demo'ing the Autologic
system. I've heard good things about it, so will be looking closely at one for
our shop.
