whats the deal with all this carbon build up on my rear end....i got a full exhaust n header, 2 new 02 sensors!?!?! and a stock cat.

 

most preludes get that...I've heard that it can be running too rich, burning oil, all sorts of things...as long as it isn't blue from what I've heard

 

i burn way more oil then i should ive heard of a quart a month and id say its more like 2!...and im not leaking ANY!?! so im burning it up...i got a buddy with a 97 lude and he gets it to but no where near as bad...could it be my rings goin or do i just crack way to much vtec lol ...to much vtec isnt possible in my book

 

vtec is what burns your oil faster because the valves are open longer. Hit vtec only when you need it...do do it evertime you are going thorugh the gears...shift aroun 3-4000 rpms and your oil consumption will go down.
