well i have a b16 in my car i recently swaped out the cold air intake to put the stock intake back on.now when i am driving the car it smells like fumes, oil. i dont drive the car hard normal daily driving it… any one one know what should i look for?
what bolt ons do you have on it still? is it tuned? you are prolly running rich
You should have a breather hose that connects to the stock intake elbow. It’s part of the PCV system, and it’s job is to draw fumes from the crankcase. If it’s not connected, your PCV system is open the fumes may be getting drawn into the cabin.
no bolt ons its completly stock. im running a p28.
yeah that breather hose that connects to the intake tube and goes to the valve cover is connected too.i
sounds like you might have left some bolts loose, check the headers bolt and gasket for leaks. you could have a exhaust leak if your useing new headers. Its almost always an exhaust leak so double check everything even the flange that bolts the cat…
he didnt say anthing about changing the header, if that was the case it was be extream an coincidence.
if your breather hose is hooked up, theres nothing more that the intake and crank case presure release system have in comon. are you sure its oil that you smell?
well I mentioned it since we dont know if his b16 came with a header or not, so if hese useing his original ls header then the possibility stands that it might hae a bad gasket or bolts loose from the head or flanges. we dont know if his swap was droped from on top or under the car. I see no point in argueing if it does no harm in cheacking.
check for oil leaks on the exhaust. specifically, under the intake manifold.
has the pcv valve been changed? try checking for leaks in the pcv system.
and you’re sure it’s oil you’re smelling and not fuel?
it only smells like burnt oil when i step on the throttle, but only sometimes. yes its a stock b16 header. well thats what i think.how can i tell?
i put the cold air intake back on and the smell of fumes went away.
today when i was driving it home my lights (hid) flickered, and i lost some rpms. it was weird.wat could have caused that.
