so ive searched and not too many on ball answers to my question. I just started up my car, last night there was a huge snow storm... There was a bit of snow in my tail pipe, so i decied to start my car up and see what it sounded like... <p>Perfectly fine, but i noticed that the fumes that were coming out of the tail pipe were black under high RPMs and black soot would come out. Now I am assuming this would be carbon build up and its normal but the black smoke part of it what is it? I changed oil about 1000KMs ago with Castrol GTX 10w-30 with a VW dealer filter (rated for 10, 000 KMs <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0"> )<p>I have not checked my oil levels lately as its been so damn cold, i know i could be low but not low enough where theres no oil and i hear my lifters, and i did not over fill it as well....<p>95 2.0L ABA with chip 2.25" exhaust and intake. Its swapped into an 85 mk2. Should i be worried?
