This isnt quite a "problem", just an observation today that worries me. I took off my UIM to clean it today and noticed it was still fairly decent (was cleaned before cougarfest I think). The only thing that concerned me was that there seemed to be an unussually high amount of oil (wet, not caked on so much) inside the UIM and LIM and all over the upper to lower gasket. It wasnt flooded, just more wet than normal. Also, I noticed a very heavy amount of carbon buildup (I think that's what the black sooty crap is) on my exhaust tip. It builds up but I wash regularly and it was way too much for just 2 days worth. It seems that I am getting a larger than normal amount of crud/ oil flowing through my engine. Does this make sense to anyone and does anyone have an idea of what would cause this and how to cure it? I plan to change the plugs soon anyway (unrelated I think) but my motor has 90K+ on it and Ive never changed the EGR or any of that stuff...pcv, etc. Should I? Could a worn EGR be dumping excess crap into my intake? Also, is this harmful to the engine or O2 sensors? I want to replace the sensors soon but for the $$$ involved in that it will take some saving. Thanks.
