These were the items I used to do the actual carbon clean, Products are
a) Lube-X compression Stabiliser
b) DupliColor Brake Cleaner
c) Gun cleaning kit, with assorted hard brushes and cotton swabs
d) Syringe to extract fluids out of Cylinder

Lots of patience and rags! :P

Before and after Pictures Of the throtte body and intake manifold.

Gave the throttle body a clean with the same compression stabiliser and toothbrush to get it all clean. After pic's include the part that is called the "BOV reference" and all that was required to fit this part was lubing the two o-rings inside the attachment and fitting the E-clip

I also gave the manifold a clean with that spray, then power washed , before replacing gaskets with fresh, new oem gaskets from BMW. There's a random pic of the pool of degreaser/stabilizer fluid that settled in the cleaning container. Included in the bov kit, was a little block off sleeve and cable tie that closes off the existing vacuum port on the manifold.

On to the hardest part of this weekend. The actual cleaning. This is the process iv used previously and did the same again this weekend. I fill the chamber in "compression stabilizer solution" which basically dissolves the carbon deposit. I let the solution sit for an hour, then scrub it with the wire brushes from the gun kit. Syringe out that "used solution" then let a fresh dose of fluid sit in the cylinders to work overnight.

Syringing out the fluid cleans out about 85% of the solution which leaves the last 15% of dirt fluid around the valves. To remedy this process, i cut up section of an old cotton t-shirt and stuff it into the cylinder, i repeat this process until iv gotten out as much dirt/fluid as possible.

Some pics of the end results, definitely cant compete with the time/effort/ cleanliness factor of doing a walnut blast but this method only cost me R600 ( about $50 ) as opposed to the R3800 ( $250 ) it costs to do a walnut blast over here. Instead of outlaying for the walnut blast, i opted to purchase the external pcv kit, which will hopefully remedy this problem. Ps i did have a BMS "High Side" OCC kit on my previous n54 and honestly there was hardly any fluid in that setup after many years and thousands of Kilometres worth of use.

Suffering from OCD doesnt help, so i spent a few more hours cleaning up the engine block and lower subframe as best as I could.

My V8 M3 Cowl Retrofit, having previously done the burgermotorsports cowl delete on my previous n54, I really wanted to do this the right way, on the 1M. It took me forever and a day to source all the parts required and it really was alot of work to accomplish this.

Please mind the dirt in some of the pictures, i assure you, i cleaned everything up when i was i done with this "Test Fit" as I am still awaiting the correct fasteners from the Dealer.

Most people cut the wires off and extend the wires to the pollen sensor, i tried a different approach by removing the insulation on the existing harness and was able to free up alot more slack on the pollen filter and brake fluid sensor wiring. I first recovered it back in insulation tape and then recovered the harness back in an OEM'ish like cloth material tape to make it look factory.

Another issue that I had was that the washer nozzles , I purchased a set of Mini nozzles only to discover that the connectors no longer fitted into the existing T-piece, so using a rubber "glove" from a terminal kit( not documented here) i was able to get the two different sizes to mate up to one another.

Another known issue is that the Bonnet sensor no longer touches the bonnet . I resolved this with the most unconventional method, using the silcone cap from a water squeeze bottle and an interior plastic grommet, coated in a lick of black paint.

Last but not least, was to install the cable harness tray which fought me for a very long time to get the wires to fit but in the end, i think it looks terrific and this is how the car shouldve come from the factory.
Hope you guys enjoy the pics and are inspired to do the same on your very own masterpieces 🙂

Non whatsover and best part is the easy access to my oil catch can, which i serviced....this was just after a few hundred kilometers, whereas my old "high side" vacuum can on my previous car didnt even catch a teaspoon of oil in a few years!

I know its not much, but its comforting to know that non of this made it to the intake valves.
