Please type more clearly. If gas is leaking into your exhaust then you have an ignition problem and uncombusted gasoline is being dumped into your exhaust. But I really can't understand what you are saying. Try to use complete words and sentences.

you blew your head gasket... check your oil. does it look milky or contaminated?

im willing to bet your seeing coolant not gas. the gas smell might be coming from the trunk. give year and model(coupe hb) engine typeDETAILS MANG!!!!!!!!! what are u revving at.

1991 240sx hatchback twincam.checked the oil and looks fine ,you are probably right on the coolant leak and why do you think the trunk smells like gas?hope is something easy to fix....motor is good ,we just think theres a leak of gas on the injectors .that means i can drive the car?need to drive it to the shop.well thanks for the help,my 240 look jst like yours only in blue.

pull the carpet up in your truck see if the fuel pump has been touched. its beside the spare tire well. looks like a wire running to a cover with 4 bolts. if someone opened that they might have forgot to replace the gasket and it wouldve leaked/evaporated into the trunk. unless u have a leak in ur fuel line/pump
