All this carbon
 

Im wondering does anybody know why I have all this carbon on my muffler. Its so thick...I know I have an 4 year old high mileage engine(148k) but is this normal? And in the mornings when i start her a lil puff of white smoke comes out...just a lil and thats it. Kinda like the seafoam smoke color. Speaking of that I used seafoam on my car about a month a half ago and is smoked out pretty good, but what else could cause this? Could it be the cat?? Im looking to purchase a new one (I put my thoughts of that in this thread) Also no lights or warnings.

not burning any oil, are you?

oh yeah I burn through some oil....especially when Im riding hard...like through the gears hard

Usually when a car burns oil, if you touch the inside of a tailpipe, it will stain your fingers black. Im thinking thats probably it, and I'm guessing that that's what Cherrington17 believes as well.

running rich? i dunno there is you never fully burn 100% of the fuel delivered into that combustion chambers

so pretty much all i can do is clean my tips huh?? any remedies??

hmm not really...... maybe dont floor it 90% of the time??? who knows?

Well you burn too much oil and it means rings possibley

lol...i know right

rings??....do go on...which rings?? Im noobish

piston rings

ah...is there any way i can know for sure or do i have to take it into the shop?....i do have leaky cam towers too

My Delta's tips look like that and it's burning oil, not that much though for a 40 year old motor.

With that milage I would vote for burning oil. The other thing is, I know you are planing to run boost, If you are not, you are using too high an Octane rating.

Higher octane ratings will leave carbon in the motor and exhaust due to it not all burning thru ;)

well im boosting now...but the carbon was there before the s/c install...hmm..maybe i should thoroughly clean it and see if it comes back now that im on 93

Do a compression test.

let the test begin...ill see how long it takes before its carbons up again....



compression test sounds like shop work

Try a tank of 91 and see if you get any pinging or bad MPG
