i have a mk4 z16xe, a couple of weeks ago i fitted a straight through stainless steel centre section everything was good at first but i started to notice a sort of well i would say petrol kind of smell but i couldnt say for definite i throught it mayb just a little unburt fuel in the exhaust last weekend i also checked my oil and topped it up only a little to the top mark. a college at my work place said to me about a bit of smoke he had noticed coming from my exhast i checked it and he was right its only a small amount and its only very high in the rev range. i thought it mite be burning a little oil?
so today i checked my oil and there was virtually nothing in it has only covered around 90 miles since it was full ive looked for oil leaks but cant find any i also checked the spark plugs today and they were black which suggests either bad ignition which i dont think it is or burning oil?
please please dont say head gasket i dont think i could handle that for my beloved astra but is there anything else i should check>>>/??? please please help
