    Carbon Cleaning Pics **Warning - Graphic**

    Seeing as how I was experiencing rough idle and some shuddering when accellerating in high gear from lower RPMs, I decided to get my car carbon blasted before progressing to meth, RBs, and a pro tune from Dzenno hopefully next month. Wow, the difference is really noticeable! Engine runs like clockwork now Click here to enlarge

    Car has 49k and the engine was never cleaned before. I've only been running an OCC for a couple thousand miles and have not seen much collection at all, though there was a fair amount in the stock FMIC when I took it out. I've been FBO AP Stage 2 for about 5k miles and was running Stage 1 for about 10k before that. I purchased the car nearly two years ago as an off-lease CPO with 30k miles on it. Full mods are in my sig

    I got the walnut blasting done at a dealership for $550 after tax. They gave me a loaner 2012 328i for the day and a free car wash afterwards Click here to enlarge

    Warning - These pics may be unsuitable for elderly pregnant people with heart conditions. I apologize for the quality as it was the service rep with his phone camera.

    That's like porting a head but only going backwards, adding material instead of opening it up. No wonder some folks experience smoother idle as well as some extra power once its restored/cleaned. Good stuff.

    I've been planning on DIY cleaning for a while now. My car just hit 29K so I think its due for a cleanup soon.
    From all the things I've lost,
    I miss my mind the most!

    I'm at ~38K on my 07 and I'm seriously considering it after seeing pics from a local guy who just had his cleaned. His was an 07 with around ~26K miles. It wasn't as dirty as the higher mileage cars, but in my opinion, it still certainly needed it.

    I've got an air compressor. I may try to tackle this myself. Someone on E90 had a decent write-up, using a media blaster and a shop vac.

    I actually have that same blaster the guy used and I've done cleaning both manual scrub and walnut shell blast. Manual took ~3hrs and walnut shell took 1hr. That difference alone is worth it to me as I don't enjoy hyperextending my knees. You do need a good compressor though with a +5gal tank. Bigger the tank and higher the pressure, the better.

    46k miles, give or take

    here is my contribution. Wasn't all that bad, but did it just before I got the AP.

    You think thats bad? Hehe wait til I find my pic on here from my bosses former 135. You cant even see the valve O.o

    Weve been using the actual BMW media blaster...wasnt cheap at about $1000. Good vacuum setup (5 gal shop vac, has to get emptied every time) will work wonders.

    Looks like the dealer left a few chunks on the sides....i usually try to get everything out. Never know when a residual chunk might break free.

    Is this the harbor freight blaster? My compressor is small though (3gal / 2.5psi at 90psi) which I don't think will work... maybe I could do short bursts? I've already done the brush scrubbing, but when I eventually do my clutch I'd like to blast it depending how it looks.

    You mean 2.5scfm? That's not enoguh. Yes it's the Harbor Freight blaster, and it works well out of the box assuming you use the "fine" grade walnut shell. I've used a roofing compressor (1.5gal, 1.2scfm @ 90psi) and it just doesn't do the same job. You need tons of air. I'd say 5scfm @ 120ish psi for a good detail. This is only achievable with a larger compressor. I rented one, can you not do the same down there for a few bucks per day?

    Yeah, I was afraid of that... I'm sure I can borrow from a neighbor.

    I can get you a better rate, but the delta would be spent in gas.

    Doesn't the head have to be pulled to blast it? $550 seems cheap for that.

    On a side note, has anyone tried Seafoaming the N54? Anyone know if you can even run Seafoam on a DI + turbo engine?
    Never thought I would see the day...

    So how do you prevent getting getting blasting media in the combustion chamber? Roll the motor over as you go or what?

    Make sure the valves are closed in the cylinder you are working.

    Then shorten the starter to make the engine revolve and close the valves in the next cylinder.

    2-3 cylinders will be closed at a time. Clean those, then you can blip the starter.
