I checked the oil after a ride like always and it looked really clear like brand new oil and i recently changed the oil and everything was fine then. So i took a rag and dabbed the dipstick on it and smelled it and it smelled a little of gas. Is there anything I am going to change the oil again before I ride and check it to see if it looks funny. Also I am not the greatest at this yet but would that mean a cracked head? what other possibilities might this be? Is it anything? Also I know i have seen the countless forums about pipe glowing red hot. Is this normal for big bore 4s? could I get a new header pipe and exhaust system to help the engine run cooler? Thanks!
