I recall my dad's similar vintage Chevy Impala had the filler behind the fold-down license plate. Thinking back now, I'm glad we never got rear-ended in either car. My '73 Porsche 914 had a 16-gallon tank, with underhood filler, just on the other side of the front "firewall" (what do you call it when the engine is behind you?) from the footwells. Not too safe, I'm sure. Of course, being in any kind of accident in that car would have been bad news. I could go over 450 miles on a tank of gas, though :-) Malcolm '88 M5 '98 328i - -----Original Message----- From: T WALROD [mailto:[EMAIL PROTECTED] Sent: Friday, September 05, 2003 12:59 PM To: bmw digest Subject: [uuc] Re: gas fill location Re: safety and aesthetics - hows about the '56 Chevy 210 wagon's fuel port hidden behind the driver's side taillight?

He said that is out of the TIS. It is not my place to question BMW's advice on this matter, but here's what I'm trying to figure out. Normally the torque applied to the diff's input flange is multiplied by the gear ratio. Let's say the example above uses a 3:1 diff ratio. So in normal use, input torque of 200 ft-lbs would be multiplied by 3, or 600 ft-lbs. I'd guess that the 600 ft-lbs would be split between the wheels. So if we're going to jack up one wheel per Gary D's procedure and apply torque to measure breakaway, why wouldn't the 50 ft-lb figure be affected by the diff ratio, only in reverse? Inquiring minds want to know. Scott Miller GGC BMW CCA ------------------------------ Date: Fri, 05 Sep 2003 18:56:32 -0400 From: Ron Katona <[EMAIL PROTECTED]> Subject: [uuc] E34 Caliper Help!

I have an 88 325 (super Eta) and it appears I have the same dual-mass flywheel and clutch as the late 325e, 528e and E36 325i, but a different flywheel and clutch than an E30 325i. Can I use an E30 325i clutch if I also repace the flywheel? Or are there physical restraints (size, bolt pattern) that mandate a different assembly? Anybody had luck with their home-towm machine shop lightening and balancing their flywheel? I'm guessing the dual-mass part makes this trickier but I'll know better after I pull it off the car. Thanks all.

Why doesn't BMW put an indicator on the fuel guage to remind you which side the filler neck is on? On my GMC truck it's a pic of a fuel pump. With two different BMW's it takes a conscious effort to remember. - -Kevin ------------------------------ Date: Fri, 5 Sep 2003 17:02:52 -0700 (PDT) From: Brad Couvillon <[EMAIL PROTECTED]> Subject: [uuc] Re: [E30Group] [E30] Clutch questions Christian, AFAIK it's the flywheel that determines which clutch to use, just as you had suspected. When I converted my '87 528e to a manual, I used the flywheel and clutch components from an '85 528e. The '87 would have originally come with the dual mass flywheel, but I used the single mass version from the earlier eta. The M20 block is the same no matter what, so it's the flywheel that matters. BTW, I think the Euro 325i uses the same flywheel and clutch as the earlier eta engine. I'm away from my ETK so I can't check it, but I seem to remember seeing that on the ETK.

A lawyer might forcefully order you to do this right away. How many plugs are stripped? Might the plugs have been installed without crush washers? The dealer's claim that a spark plug can be stripped by an overrev is the biggest of the most ludicrous malicious excuses I've ever heard a dealer try to feed a customer. When a mechanical overrev occurs the first damage that happens is bent valves, due to the nature of the hydraulic lifters. When I had my overrev, the OBDII readout said I reached 7800RPM. Bent exhaust valves but no other damage. What might happen if the piston top hits a spark plug? I had that happen on my '97 after the inspection II was done at Claridge's BMW in Fremont, CA. The motor ran wrong after I got it back from the 'free' service. All cyls were firing but power was more like a 325, and economy was down ~10%. (<20mpg versus a consistent ~22.5 in local/suburban driving) I pulled one plug at random and it was bingo. There was a wrong plug in my motor. In two of the six cylinders they used a single electrode plug that both had a longer threaded section and an electrode which reached over the tip. The other four plugs were the correct OEM plug. The two wrong plugs had electrodes bent over, and the tip insulators were cracked. But no stripped spark plug threads. Why btw, does BMW say that a heli-coil should not be used? They've been around for decades and are the standard fix for stripped plug holes. ------------------------------ Date: Fri, 05 Sep 2003 17:22:17 -0700 From: jkerouac <[EMAIL PROTECTED]> Subject: re: [uuc] [E36M3] Following up with trouble with spark plugs re:[uuc] [E36M3] Following up with trouble with spark plugs: Can you get ahold of those spark plugs they claim stripped the threads?

When performing the breakaway torque test, you are only measuring the torque from the preload springs. A 25% LSD means at most 25% of the input torque can go through the clutch pack. The % is determined by the preload and the number of clutch plates inside. 25%, 200 ft-lb engine therefore 50 ft-lb is completely wrong.
