Jim, Chester et al: My engine was just completely rebuilt at 140,000km (90,000miles)... this saga started with oil consumption which had reached one quart per 600miles ... leakdown and compression were almost perfect and valve stem seals was initially identified as the culprit ... when the head came off the amount of carbon on the pistons was significant and the diagnosis was changed to piston rings (yes, despite the near perfect leakdown) ... since rebuilding, following a robust breakin to really set up the rings this time, and now running only 15W-40 mineral oil as recommended by BMW (I may switch to synthetic again eventually, but not until I am absolutely certain the rings are set up!!!), I am now burning zero oil - even better than when the car was first broken in?? I mention this so that 1. you don't put your motors back together until you are sure the rings are OK ... 2. if rings, you consider using mineral for a significant period to complete breakin very well ... 3. you read the breakin recommendation at http://www.mototuneusa.com/break_in_secrets.htm Good luck, Doug

Thanks for the feedback, but this unreasonable to do at this point. Pulling the head is easy. Getting the pistons out involves ALSO dropping the bottom end, which I am not prepared to do in terms of either money or time. And as I mentioned earlier, I'm already planning on doing rings/full rebuild/replacing the motor at a later time. > 2. if rings, you consider using mineral for a > significant period to complete breakin very well ...

#6. Coughing Engine? - from twisty M3

Date: Thu, 18 Nov 2004 19:23:09 -0800 From: "twisty M3" <twistym3@hotmail.com> Subject: Coughing Engine? Odd thing has happened on my drive to and from work today and yesterday. Other than this, the car has been running fine and strong. As the car gets to idle, it will sometimes cough (hard enough that I can feel it with the radio on) and then stumble for about 5-10 seconds. It's returned to normal after that so far, but I'm wondering what I should be prepared for. The car is a '99 with 135K miles, sharked, intaked (both for the last 100K+ miles), driven daily and used heavily on track. The most recent addition to the car is the UUC Stage 2 flywheel/clutch, but that's been in for about 4K miles. Thoughts? Jonathan L.

Here's the diagram and parts list, showing the exhaust system: http://tinyurl.com/3hw4e While the diagram only shows two O2 sensors, the parts listing shows that the quantity required is TWO for each. So, the car definitely requires FOUR, two pre-cat and two post-cat. I wouldn't trust a mechanic if he's either: 1) mis-reading the repair manual/diagnostic/computer output, or 2) has never looked at an OBDII E36 M3 to know that it has four O2 sensors. -rb

Hi, Normally control arm or control arm bushing failure can be detected under braking. $800 for the control arms is *HIGH*!!!! You can get a set of arms (steel) for $150 if you look around. Urethane bushings are about $90. More than $300 for the work is toooooooo high. Run from that guy. For $600 in labor I had the following replaced and this included a four wheel alignment with printout. 1. Both control arms an bushings 2. Front struts 3. Rear Shocks 4. Upper shock mount bushings 5. Misc parts and alignment. $800 for the arms, yikes!!! scott noltensmeier wrote: >Date: Fri, 19 Nov 2004 14:52:34 -0800 (PST) >From: scott noltensmeier <snoltens@yahoo.com> >Subject: 96' M3 w/125K -- Control Arm: Do I need to replace the entire arm? > >96' M3 w/125K -- Control Arm: Do I need to replace the entire arm? > -- or can I replace just the bushings? >A mechanic wants to replace the arm, cost $800... says its necessary due to the high (125K) miles. >Also...
