MotoIQ’s Project E46 M3 uses Liqui Moly Engine Renewal Kit

Sep 28 17

In a recent MotoIQ article (Online performance automotive magazine), author Pablo Mazlumian performed some preventative maintenance on the Project E46 M3, using the Liqui Moly Engine Renowal Kit and full synthetic GT1 10w-60 motor oil from Bavarian Autosport (BAVauto®).

The Engine Renewal Kit includes the Liqui Moly Engine Flush, Ceratec,  Jectron and Ventil Sauber (see descriptions below) and helps to keep the engine free of oil sludge and varnish build-up (especially piston ring land varnish), reduce power and durability robbing friction and wear and keep the intake valves and fuel system free of varnish and carbon build-up.

Liqui Moly GT1 10w-60 fully synthetic motor oil is specifically approved by BMW in Europe and is an excellent choice as an improvement over the factory BMW 10w-60 oil.

Here are a couple excerpts from Pablo’s article:

It’s that time again so we’ll be doing some maintenance updates using German-made Liqui Moly products from Bavarian Autosport, including 10w-60 weight oil and Mann oil filter, Liqui Moly’s Engine flush to remove carbon build up, and Liqui Moly’s Ceratec lubrication for the internals.

When we finished our oil change using the Liqui Moly 10w-60 oil (as recommended by BMW for normally-aspirated M3s and M5s), we went ahead and included a bottle of Ceratec, which should help further eliminate friction and lengthen piston side skirt life thanks to its ceramic protection. We have been adding it to roughly every other oil change in this car [Liqui-Moly’s recommendation is every 35,000 miles).

BAVauto® Show and Shine 2017 – Wishing You Were Here! Photo Gallery

BAVauto® Show & Shine
Customer appreciation and charity raffle event

The day started with early morning drives from the north, south, east and west with the orange sunrise hanging in the east …. err … wait … back up a minute …. with an early fall fog blanketing the fields and valleys … yup that’s it!

So, as the day dawned, the BAVauto® employees and Show & Shine volunteers arrived and headed straight for the coffee tent, fueling up for the Show & Shine set-up.  The specialty theme, this year, was BMW Classics and the experienced parking crew quickly filled the front display lot with 24 examples of BMW’s classic designs.

By 8:00am, they were aligning and parking the 300 (or so) BMWs and MINIs who’s owners patiently waited in line to show off their pride and joys.

Meanwhile, the manufacturers and suppliers of many of the parts and accessories offered through the website, were setting up in the 20′ x 80′ vendor tent …. anxious to greet the attendees with thanks and offered assistance.

By, 9:00am, free raffles giving away thousands of dollars in BMW/MINI parts and accessories as well as the charity raffles (with thousands more in prizes) were divided by interviews with the owners of the BMW classics displayed in the front lot.  The free lunch  (burgers, brats and hot dogs) was ready by 11:30am.

After more free giveaways, the charity raffle grand prize was drawn …. an all-expense-paid trip to a BMW Performance Center and a day of ///M Driving School with associated sightseeing and expenses.  The charity raffle raised just shy of $10,000 to go to Susan G. Komen, Disabled American Veterans, Animal Legal Defense Fund and Be The Match.

BMW 3-Series PowerFlex Trailing Arm Bushings (RTAB), install, E36, E46, Z4, X3

Sep 15 17

Bavarian Autosport has been sponsoring BMW project cars for the online automotive performance magazine, MotoIQ, for some time.  BAVauto, in partnership with author and BMW performance geek, Pablo Mazlumian, has assisted in various E36 and E46 M3 project car builds as well as maintenance.

In Part-19 of the Project E46 M3 articles, pablo installs PowerFlex RTABs (Rear Trailing Arm Bushings), using the BAVauto RTAB remover/installer tool, which allows easy bushing replacement “on the car”.

We have found that the BMW models that use these rear trailing arm bushings will show unstable road manners and even a sense of “rear steering” as the bushings age and become soft (or worse).  Additionally, worn RTABs can cause a clunking over bumps or when transitioning between acceleration and deceleration.

See our RTAB tech article, with removal/install DIY video, by clicking the image below:

In Pablo’s article, he notes:
“The rear trailing arm bushings (RTAB) on BMWs are rubber and are prone to cracking. I’ve had them go bad on previous E36 M3s, and the symptoms were simple to discover and quite obvious. One of the easy ways was to accelerate the car hands-free of the steering wheel. If the rear pulled to a side, you most likely had bad bushings.

I didn’t figure it out so easy on this car, however. It wasn’t until I took a high-speed, four-gear turn on an uneven cement on-ramp that I could feel the rear end dancing around with so much grip from the surface (cement usually has higher grip than asphalt). It was very unnerving, and quickly made me lose confidence in the car.

Upon a quick look underneath, it was obvious the car’s RTABs were wasted. The car just clicked 70k miles, so it was no surprise.”

Here are some highlights from Pablo’s MotoIQ, Project M3 article:

These polyurethane pieces are modular and go together like so. These bushings allow for an easier install, because with a rotating mass there is no pre-tensioning. These particular RTABs should fit all E36 (except ti), E46 and Z Series cars.

Trying to remove a factory bushing without the proper tools can become an act of futility. Bavarian Autosport sells its own trailing arm bushing tool that is specific for this job. It will be used both for removing the old ones and installing the new Powerflex units.  The Bav Auto trailing arm tool appears to be very high quality, and it features CNC machined components.

With the bolt out, the bushing was now able to be free of the housing. That sucker is really torn up! It’s no wonder the car felt so unsafe during high speed cornering, especially mid-turn when you’re trying to maximize the G-load to the front tires so you can get pointed where you want to and immediately get right back on the gas. It was all over the place, feeling like something was loose or practically broken. It was like driving a car with a mild, yet unpredictable rear steering!

These bushings are going to be really on there so to remove them, line up the Bavarian Autosport tool like so.  Now simply start tightening the inside nut with your wrench or gear ratchet.  You’ll notice the bushing’s stickiness start to give way, and little by little come on out.

Here’s another look at the original bushing fully removed. One can opt to purchase factory bushings again, by why when you’ve got polyurethane units from Powerflex that will give you a tighter feel and much crisper response without really any drawbacks.

What we did was mount up the tool again in order to start pressing the new bushing in.

“With the new Powerflex RTABs in there, the confidence in the car is back. You can throw the car into a turn under hard trail-braking and not worry about that back end stepping out. Also, the worry of driving over an uneven payment is a thing of the past. That new, tight feel is back!”
