#1. Exhaust Hangers - from Mark D
Top
Date: Mon, 08 Oct 2007 21:21:47 -0400 From: Mark D <mdlkml@atari-source.com> Subject: Exhaust Hangers Hey guys, Can someone more versed with exhaust replacement let me know which parts go bad? Just the squishy parts or the brackets too? I can get SOME of the brackets from autohausaz but seemingly not all of them. The part numbers I have are (squishy parts) **18301703634 (2 per car)** **18201401797 (2 per car)** If I should really replace more than this please let me know. Rust shouldn't be much of a factor since this car is a garage queen. Thanks, Mark

Just the squishy parts or the brackets too? The soft rubbery bits that you listed are about all I've replaced, although the last time I may have also replaced the hex nuts for the rear hanger on the race car. But yeah, you pretty much have it covered. Jim Bassett

Although if you test yours and find that it doesn't work, I'll send you one with a kit. They are not new, but as you said, they are always tested. The rattling noise is typically the #1 reason for replacement, but the lack of low end power, or just the 'while you're in there' reasoning is pretty common too.... especially when installing cams, but a rattling vanos does not necessarily indicate that it's going bad. I would do a $25 discount on either kit with at least 4 people on the GB. The website goes into a fair amount of detail about the differences between the two kits and has some pics, but I highly recommend the stage II. :-) http://drvanos.com/spec2.html Feel free to contact me offline with any questions.

Anyone else out there interested? Stage 1 is specifically what I would be purchasing. Do your rebuilds include a new solenoid or do you test and replace as required? My car has the marbles in a can noise and seems to be sluggish below 4k so I think it is time to replace the unit.

I'm sure high miles and lower compression has something to do with it but that doesn't explain why I feel such a ridiculous surge of power at 4000 RPM. Does anyone, anyone at all have the electrical portion of the vanos tester or have a reasonable facsimile of test voltages to feed it? I can get the air portion of the kit easily, but I don't know how many volts the solenoid actually takes between full and no engagement. I can't see spending the money on a part I don't know is bad. I have a very smooth idle (with cold start roughness for 30 seconds) and no codes thrown. Thanks, Mark

#9. Re: [E36M3] Rear end wiggling under braking - from Azik [Hotmail]

Date: Tue, 9 Oct 2007 09:41:45 +0200 From: "Azik [Hotmail]" <azik@hotmail.com> Subject: Re: [E36M3] Rear end wiggling under braking Mike, that was a first in this M3, I had more in my old M3 3.0 and my 528, both didn't express that. the behaviour of the car was scary. One experienced driver drove it as well and admitted that for factory suspension there is too much instability. In fact, he had to brake in one corner because of one biker and rear immediately broke loose and we were throuwn out of the track. I have video footage of this but my hand went down as we started to slide :) I have Bridgestone potenza RE050, they have still lots of thread left but the rears are with "MO" mark, means for Mercedes, stock sizes (225/45 17 front and 245/40 17). When I look closely to the thread, some of the water routes are blocked on rear MO tyres compared to fronts. so they are not exactly same. may be its a size difference, 225 to 245. But that day was dry and very warm, track was probably 35-40 deg C. I now think these are shock absorbers. the test has shown that fronts are hard, rears are medium-hard. The amount of time the wheels spent on surface while vibration test for front is 56/59% and for rear is 36/40% I am not sure if you do similar tests in US but I have two pages full of numbers for brakes and shock absorbers. everything looks OK except for slight softness of rear shocks and the difference between rear wheels in the resistance to rolling - left has 119 Newtons and righ 181, which is 34 %. that was the only red flag.
