Saturday, June 24, 2017
I'm within a few weeks of pulling the engine now.

As usual, all the details can be found on the other side of the click.

Friday, June 16, 2017
The drivetrain overhaul project continues to ramp up. This week some critical tools including the torque plate arrived and I completed the first of a few big parts orders with my dealer. The ShureShop table also arrived and I managed to partially assemble it with my brother's assistance but that didn't go as smoothly as expected. This and more awaits in the latest installment.
BMW330ci: Driver's Airbag Replaced
Friday, June 9, 2017
After waking the E46 from its deep winter slumber I conducted another low utilization oil service and then made an appointment this week with my technician to replace the driver's side airbag under BMW's Takata airbag recall campaign. I also acquired an article recommended by my technician that explains the history of the recall and why, if your vehicle is subject to this recall, that you definitely want the bag replaced. For the details, as always, check out the full story.
BMW328is: Pistons Arrive
Saturday, June 3, 2017
The pistons and a lot of other miscellaneous tools and supplies have arrived. I bought the Beisan Systems Vanos overhaul kits and clarified why no thrust bearings are included. I also made some progress on the 100W LED task lighting project and found the initial performance promising. My drivetrain overhaul project is starting to (forgive the pun) rev up, so you'll want to check out the latest installment.

Saturday, May 20, 2017
While trying to write up instructions for my machinist I received a call from Steve at Top End Performance to clarify how I should bore the block.

The prep continues in the latest installment of my drivetrain overhaul project.

Friday, May 12, 2017
Research on the transmission overhaul continues. I have learned more about the process, tools and equipment needed to tackle this job.

BMW328is: Drivetrain Overhaul Parts List
Sunday, April 30, 2017
Over the last couple of weeks I collected a list of tools, equipment and parts I'll need for the drivetrain overhaul. I also developed a blueprinting spreadsheet that I figure will come in handy when I'm rebuilding the bottom end of the engine, contemplated rebuilding the transmission myself, and sent a few more questions to the JE Pistons rep. If you've enjoyed reading the ramp up to my drivetrain overhaul you don't want to miss this installment.
BMW328is: Engine Overhaul Update
Saturday, April 15, 2017
I discovered the reason why my first choice piston vendor was not answering their phone and wound up researching additional options for piston replacement. I also got around to making the compression ratio calculations to determine the consequence of boring the block to 84.5mm, had the first detailed conversation with my head rebuilder and even researched the specialized tools I'll need to assemble the bottom end. Lots of geeky technical stuff ahead.
BMW328is: More Engine Overhaul Research
Saturday, April 8, 2017
Seeking to purchase another BatteryMINDer I found the models I own are now discontinued, but I may have found a suitable replacement.

Lots to talk about so do yourself a favor and start reading.

Saturday, March 25, 2017
After another annoying but slightly warmer than average winter season the summer tires have been reinstalled.

Check out the full story.
Tech: PDP8 Replica Build
Saturday, January 28, 2017
Although I don't have anything resembling free time these days I bought a short-run PDP8 replica kit last year and figured I'd take a few hours this week to assemble it. I didn't pick up a teletype to go with it but for some reason I can hear one chattering away as I type commands in the OS/8 console. Old school computer geeks will want to read the full story.
BMW328is: New OBC Coded
Wednesday, December 7, 2016
I arranged to stop by my technician's bay to have the new OBC coded and it took less time than expected. Before we got to work, however, I got an opportunity to experience BMW's new hybrid drivetrain in an X5. Great tech, but as usual the long term maintenance costs turn me off. Check out the full story.
BMW328is: New OBC
Sunday, December 4, 2016
The OBC backlight failed again so I put it on the bench to finish up the repair I started a couple of years ago. Unfortunately I was unable to correct the problem so I ordered a new OBC while they were still available. The new unit has yet to be coded, but it will be installed soon. This and more in the latest maintenance update.
BMW328is: Evap Tank Replacement
Saturday, November 19, 2016
In an attempt to remedy an intermittent indication of a minor leak in the evaporative emissions control system I decided to replace the expansion tank located in the right rear wheel well. I'll classify the end result as "so far, so good" but I've only been through a single drive cycle. Only time will tell if this work has fixed the problem.
BMW328is: Engine Overhaul Research
Saturday, November 5, 2016
Over the last couple of weeks I investigated the evap control system problem causing the CEL, continued my engine overhaul research and finally got to see the "new" M2 in person. Lots to report on, so grab your computing device and get comfy.
BMW328is: Fall Maintenance Binge
Wednesday, October 19, 2016
Some people enjoy getting out and leaf peeping this time of year. BMW owners like me see this as the last chance to get a bunch of long-postponed maintenance done before the snowflakes begin to fall. I tackled an oil service and power steering flush, replaced the failed fan clutch and pre-cat O2 sensors, and more. If any blog entry qualifies as jam packed this one does.
BMW328is: CEL Diagnosed and Cleared
Wednesday, September 28, 2016
I got the car in front of my technician to diagnose the recent CEL and it turned out to be another annoyance. With the days getting shorter I finally tested the ZKW headlight performance on a stretch of unlit road out in the sticks and I'm impressed, to say the least. I also managed to do some paint correction on my brother's new C4 Corvette. After all, I'm not the only one in my family that prefers older cars.

Saturday, September 24, 2016

Saturday, September 17, 2016

BMW328is: Foam Repair Experiment
Saturday, September 3, 2016
Although the leather project is complete I had already bought the materials to repair my foam so I decided to perform a small scale repair as an experiment simply to validate the materials and techniques I had planned to use. I also managed to apply leather conditioner to the new leather and it still smells great! Check out the full story here.

BMW328is: Front Seat Refurb and Assembly
Friday, August 19, 2016
The driver's seat is complete and ready for installation. I'm glad I took the time to repaint the seat base as it nicely matches the new leather and overall makes the seat appear brand new. It's clearly ready for another eighteen years of service. Check out the end result.

Full story here.

Thursday, August 4, 2016
I found some time today to install the new leather cover on the rear seat base, install the seat base in the vehicle, and with that wrap up the rear seat leather installation. The end result is better than expected. And yes, if you're wondering, the interior is starting to smell like it's 1998 all over again.

Tech: Nuttx for STM32F3 Discovery Board
Saturday, July 30, 2016
Earlier this year I selected an RTOS to assist in bootstrapping an STM32 F3 Discovery development board as a stepping stone to custom hardware. While the documentation provided by the project was adequate I ran into a few issues so I figured I'd document them here.
Tech: STM32 Debug On Linux
Saturday, July 16, 2016
I recently needed to develop some software on the STM32 series of microcontrollers and wanted to debug my application from a Linux host. I managed to select a debug probe and some software to get the job done. If faced with a similar need you may find my STM32 Debug article helpful.
BMW328is: Rear Seat Trim Repair
Sunday, July 10, 2016
I received confirmation from GAHH that my covers arrived in one piece and I breathed a sigh of relief. While I wait for the new covers to be fabricated I decided to attempt repair and restoration of rear seat trim pieces that are no longer available new from BMW. I think the they came out great. See for yourself.
