well like it says i have a big carbon problem, i dont know what to do i did everythin i could think of, i did a total tune up like i do twice a year, plugs, wires , timing,. iv asked for help befor but i dont think anyone knew what i was sayin. my problem is that i get massive carbon sute on my rear bumper from my exaust, but its not b/c of my exaust its brand new and plus i had this problem before the exhaust went on, so if someone could plz help me it would be great,

Oh my set up is D16A6, stock engine, cold air, and catback system.

PLZ help.

 

Are you sure you aren't running really rich, or have a leak somewhere so liquid is getting past, into the exhaust grabbing the soot and splattering it on the bumper? I'm just saying that because I was dealing with that situation for the longest.

 

Sounds like you might be burning oil or that you are running too rich.
What engine, what mods, and how many miles on it?

 

i am running everything stock exept for the cold air intake, there is just over 222 000km on my engine,and well my valves are LOUD like u can her them clear as day over my cold air, so maby thats it, i dont really care about it anyway, will be swaping a complete Z6 Engine tranny in soon, but i would like to save my exaust system, i dont want it to be all pluged up with sute. is there a way to save it if it does get pluged?

 

Anyone?
