BMW DIY Video – Carbon Cleaning N54 and N55 Intake Ports and Valves, De-Carbon, Walnut Blast

Jul 2 14

Come on along as we perform the de-carbon service on a 2007 335i. This vehicle has about 72,000 miles on it and had had this service performed previously, at about 45,000 miles. As you will see, from the video and photos, in just under 30,000 miles, there is significant carbon build-up in the ports and on the intake valves.

It is important to put the vehicle in “sleep mode” before beginning any work.  This powers down all modules and computers, allowing the various sensors to be disconnected without generating faults in the systems.  Perform this step as follows:

1) Place the vehicle in the position where it will be worked on.

2) Open the hood and the driver’s window.  Close all other windows, doors and trunk.

3) Turn off all systems and accessories and remove the key.

4)  Move the key at least 20 feet away from the vehicle.

5) Apply parking brake and place transmission in NEUTRAL (manual transmission) or PARK (automatic transmission)

6) Wait 20 minutes.

7) Once the vehicle is in the sleep mode, do not activate any electrical accessories or systems (besides bumping the starter, as shown), close the hood or open the doors, trunk or windows.

As we move further into the 21st century, many auto manufacturers are turning to engine management systems that employ “direct injection” fuel injection systems. Direct injection systems inject the fuel directly into the combustion chamber at the precise timing for read more…

This DIY (Do It Yourself) How To Video shows how to install the Powerflex urethane bushing sets in the rear subframe, trailing arms and differential mount on a BMW E30 3-series (84-91).  While the specific model shown is an E30 chassis, these general procedures are applicable to all early BMW subframe and semi-trailing arm chassis (Bav, CS, 2002, E21, E12, E28, E34, E24, E23, E32, E31) as well as the E36 based Z3 and 318ti.

Follow along as we perform the bushings install on this 89 325i:

One of the most common maintenance and/or upgrade areas on our BMWs and MINIs is the various suspension bushings. We’ve talked at length about the front suspension control arm bushings, in multiple Fast Times articles and DIY videos. In this DIY article and video, we’ll take a look at the read more…

Step 7:
Maintaining the Shine

Now that your BMW or MINI is looking so nice, don’t let your hard work go to waste – maintain that shine!

1) Weekly or as needed: Use dusters, microfiber towels or polishing cloths to remove dust, pollen, etc., from waxed surfaces.  Also remove sap or bird droppings as soon as you notice them – if left on the surface for any length of time, they can ruin the glossy finish you worked so hard to produce.  For on-the-spot paint cleaning and dusting, we recommend keeping a Car Duster and Microfiber towels in the trunk.

2) Twice a month: Wash and dry your car and clean your wheels. (If you live in an area where they use road salt or sand in winter, give your car a thorough rinse between washings). Hand washing is best because it allows you to inspect the exterior up close. Plus you know the water is clean, the wash brush isn’t gritty or grimy and the soap isn’t too harsh. If you must use an automated car wash, use a touchless one. To restore some luster after the car has been washed and dried, use Zymol Field Glaze, SONAX Brilliant Shine Detailer or Smartwax Smartdetail. Spray it on, wait 10 seconds and buff lightly with a lint-free cloth, such as a microfiber towel or Sontara wipes.

3) Once a month or as needed: Wax the car and your wheels. If your car is garaged, never parked in direct sun and rarely driven in the rain, you may find that your wax job lasts longer than a month. If your car is in the sun constantly, driven in harsh conditions, etc., you may need to wax more often. How do you know when you need to wax? When you wash your car, watch how the water behaves when you rinse. If you see tall, round beads of water, the protection is good. Oval flat beads indicate the wax is losing its effectiveness. A sheet of water indicates virtually no protection. Is it possible to over-wax? Yes, but only if you go to extremes and wax more often than once a week. If you go two weeks or longer between waxings, buildup should not be an issue.

4) After six months: Cleanse the paint again. Using the clay bar at this point is optional, depending on the condition of the paint.

5) Once a year: Perform the first six steps outlined in this newsletter. You are certainly welcome to do these six steps twice a year – it won’t hurt your BMW or MINI one bit. Follow this simple schedule and you’ll keep your BMW or MINI looking like a concours winner all year long.
