Carbon build up before and after

thyshallsmite · 06-24-2013, 10:18 PM

Thought you'd guys like to see just how bad our n54 carbon build up can get, this was after about 60k miles with no catch can (bought it used)

before:

after:

Catch can and cleaning definitely needed for this engine ><

cwarren · 06-24-2013, 11:29 PM

holly crap I just did mine and it was nothing like that...

blacknbean · 06-25-2013, 12:17 AM

wow that might be the worst buildup ive seen on this site lol

TTurbo335 · 06-25-2013, 12:56 AM

that looks gross!! Original Owner probably never let her rip!

Glad it's all clean. Enjoy

carlsontheflyer · 06-25-2013, 09:00 AM

Wow!

Was there ANY air going in? With that much buildup the engine must have felt like it had emphysema. You should feel an enormous difference in the way the car drives.

I would recommend you do not wait another 60k miles for the next cleaning. My car was really bad after 36k miles, so every 30k or so. Sooner if you make many short trips and don't allow the car to warm up properly.

I just hit 70k and am planning on doing mine for the first time sometime this summer. This is what I have been expecting mine to look like!

335xi Kevo · 06-25-2013, 09:42 AM

You have taken the cake. Those look like rs4 valves there that bad.

deathbunny · 06-25-2013, 10:13 AM

OMG I cant believe it was able to still run looking like that

engine is quite the champ, was running it up to 150mph with no trouble (closed road of course)

ZROFCKSGVN · 06-25-2013, 11:38 AM

did this a few months back and will probably do so again in a few more months, for n54 engines this is a MUST!

Jeff@TopGearSolutions · 06-25-2013, 11:44 AM

That might be the worst I've seen on this platform. Or just the best picture with the highest resolution the size of Rhode Island. I can't tell yet

pwr hungry · 06-25-2013, 09:26 PM

I wish I still had the pics of mine...the cleanest one was worse than that one! You definitely got your cleaner than I did too!!! Walnut blast?

E90Company · 06-25-2013, 09:38 PM

That's the worst I've seen posted on the forums of N54 valves. Clean picture looks like new!

WesleyC · 06-25-2013, 09:55 PM

Lifted07Duramax · 06-25-2013, 09:59 PM

Defintely worst I've ever seen. But damn it cleaned up well

walnut and metal pick, some were so bad that the walnut blasting couldn't get it

zeel · 06-25-2013, 10:57 PM

I expect swamp thing to come crawling out of those valves.

Holy moly.

sankohuy · 06-26-2013, 01:46 AM

Man I wish I have the guts to DIY this...

rooringhusky · 06-26-2013, 05:27 PM

Did mine at 80k for the first time and even though I thought they would be this bad, they werent! Surprised yours looks like this with 20k less miles...

Great post OP and very cool pics to look at..

Snypa · 06-26-2013, 07:12 PM

Pretty graphic!--how did it feel after cleaning?

EJ_3 · 06-26-2013, 11:58 PM

Definitely will have to get this done.
