Here is a weird one...
So my original alternator probably went bad, it did have a wobble in the
shaft and my voltmeter did show a reduction in charge when the belt
squealed.
But after replacing the alternator with two different units, both of which
sounded bad - I was stumped and took the car to the dealership, thinking
the terrible noise I was hearing may be coming from the Power Steering
pump. The tensioner pulley spun freely - so it wasn't that.
Turns out the mechanic that installed the 2.5L into my 318Ti (done back in
'97, by previous owner) didn't install the top side idler pulley that
pushes down on the belt between the alternator and water pump pulley. The
dealership installed this part - noise gone, car runs like a champ (though
it ran like a champ before)
How strange. Can't figure this one out - why it ran fine before - no
noises, no squeals. But one day....

There were two different methods of tensioning belts on E36 six cylinder
engines. Mine uses a single idler pulley with a mechanical tensioner.
The other method and the replacement method, uses a little hydraulic
strut with two pulleys. Maybe you had the former and the dealer replaced
it with the latter.

Well the M50 is from a 1993 325i, which leads me to believe that it should
have had the idler pulley, bolted to the top alternator bracket.

2 guesses:
One, the spring in the tensioner was strong enough to keep tension on the belt without
the idler. After 7 years the spring is no longer strong enough to keep the belt from
slipping.
Two, the belt that was on there (have you replaced the belt before now?) was shorter
than stock to compensate for the missing idler and the tensioner doesn't have enough
travel to keep tension on the new stock-length belt.

Yes, it should. If the tensioner is the mechanical spring-loaded type you should have
an idler on the top alternator bolt as you describe.

I need to replace my head cover gasket and note in the Bentley manual that some sort
of sealant
needs to be used in the half crescents at the back of the block. Is this something
dealer specific.
If I go to a track auto/autozone kind of place, what equivalent product am I looking
for?
Also, I noted that the torque on the cover bolts is something like 10 in/lbs (?)
wou8ld that be
finger tight? or is it time to go buy a smaller torque wrench?
Thanks,

Use O2 sensor safe RTV. i.e., no silicone content.
Bolts should be cinched down. Not finger tight, but you don't need an 18"
breaker bar either.
Use a 1/4" drive ratchet and just give them a tweak after they bottom out.
The nuts are designed to bottom out on the stud, so they don't apply too
much pressure to the rubber gasket.

Peter,
Bavarian Autosport http:www.bavauto.com carries them. P/N 11 53 1 722 531 $31.95.
I think BMP and Ultimate Garage also carry them at similar prices.

Well then, surely there are tons of these sitting in Japanese junk yards waiting to be

Ah yes, the gasket difference. I keep forgetting they changed that.
Since I've had the early aluminum housing for years I was just wondering
what you meant by the early al unit being a downgrade from the later al
aftermarket units. Now I'm clear.

re: E36 axle ratios:
Would that Japanese market 3.73 be as heavy duty as the E36 //M3 or in
the same service strength as the 3.45 from the 318i?

Subject: E30 Steering Column Question
Message-ID: <[EMAIL PROTECTED]>
I'm tracking down the source of a noise in the steering column of our
'91 325iA. Note that this is an airbag car, and there may be
differences in the column relative to the earlier non-airbag cars.
The steering shaft (the part that actually rotates with the steering
wheel) comes down from the steering wheel area towards the firewall.
There, it has what appears to be a slip joint that connects it to a
splined shaft that goes through the firewall. The play that is
causing the noise appears to be coming from the slip joint. OK, while
it might be called a "slip joint", I would assume it is supposed to
slip fore and aft, not with rotation. Anyway, it has a large-ish nut,
maybe brass. It is begging me to tighten it up.
Wishing to avoid possible over-tightening, I thought I'd look in the
Bentelely manual for a torque value, or some other clue as to the
amount of tightness required. On page 13-39, figure 7.3 shows a
steering column where it goes through the firewall. Only, it is
completely different than our car. The actual rotating part of the
column is hidden inside a tube. The tube attaches to the firewall.
I'm sure this picture is from a non-airbag car, and conclude that the
airbag column must be different.
Right? Or is my car supposed to have this tube that hides the actual
steering column?
Any insight would be appreciated, including how much to tighten the
collar nut on the shaft (which, of course, I'd have to estimate, since
a torque wrench will not work here), and/or how to tell if this thing
is worn out and in need of replacement.
Please include a cc to this address if you reply to the list. Since
I'm in Digest mode, when I might see your reply is entirely dependent
on how many of you feel like chatting today.

Scott-
I have done this to two '90 E30's (a 325iS and an M3) with success in
toning down the rattle noise. The way I did it was from instructions
given by Don Fields on the E30 M3 SIG.
First, turn the steering wheel all the way to the right. Then, got a
large open end wrench (I used an adjustable open-end) and put it on the
nut. I braced the bottom of the wrench against the floor and one of my
foot pedals. When the wrench was in place and steady, I started turning
the wheel to the left. I cannot tell you how tight to go with it, but I
got it as tight as I could. Don suggests that you hold the wrench while
a buddy turns the wheel for you. This would be easier, but you can do it
yourself if needed.
In both cases, the knocking noise from the steering column quieted down.
The 325iS still had some noise, but not as bad. I feel the reason it
still has noise is that the rubber flex disc/u-joint in the steering
shaft is very worn and makes the remainder of the noise. The M3 was
almost totally quiet after this.

O.k. now I'm really curious--why is this diff not very good? (lack of
performance or reliability?) Why do you suppose BMW chose it over the
"clutch pack" type for this application? Can you give me a quick "pros

The "looseness" permits the traction control, stability control, etc. and
