White fumes in the engine oil filler cap

Clogged up PCV System ---maybe

Too much crank case pressure

Hi there?
It sounds like the EGR valve is stuck open letting the exhaust fumes enter the engine. Since the exhaust smoke has no oxygen then the engine won't start whout oxygen (fresh air). Disconnect the pipe going to the inlet manifold and see if the engine starts. If it starts then you need a new EGR valve.

I doubt the oil is boiling in the sump or your engine would show signs of over heating. Change the PCV valve in the valve cover as it may be stuck closed causing internal pressure to build up and escape through the filler cap.

Hello, and welcome to FixYa. Please allow us to assist you.

You have a verry common condition; we see this quite often.

The codes you mention are usually caused by one (or a combination) of the three things that follows.

1. You do not have the 'factory' fuel tank cap fitted to the car; 'Aftermarket' fuel caps do not seal properly, and the leak of thefuel fumes under the cap will light the light.

2. The o-ring that seals the cap to the fuel filler neck is worn, or otherwise compromised, which will also allow the fumes to escape and light the light.

3. There could be rust on the filler neck tube, which would not allow a tight seal between the cap
s o-ring seal and the filler neck.

I would recommend replacing the fuel cap with a factory replacement, and inspect the filler neck sealing surface for rust buildup. If you see rust, a replacement filler neck will be in order.

Thanks for choosing FixYa fo assistance today.

normally fumes come in to vehicle when stopped because of oil leak from rocker cover but check your fuel filler cap seal etc and also incase the tank is leaking just have a sniff at the rear of the car if its the filler cap or tank filler you normally get smell when tank is nearly full and been around a few corners the fuell filler nect becomes pourous and just spills out a bit if so will need replacing .but most time its an oil leak from rocker box or engine

White smoke from the exhaust is a common symptom of water getting into the engine via a leaking head gasket.

Check you coolant level. Has it dropped below normal?

Check the oil filler cap. Are there any signs of a whitish-brown emulsion in the oil? (This is a sign that water has contaminated the oil.)

If either of these are present, get the engine check professionally ASAP. Continuing to drive it may cause irrepairable damage.

Hope this helps!

You can't see it from the top because the oil pan and drain plug are on the bottom of the engine. You will probably have to jack up the car in order to crawl underneathand reach the drain plug.

You should change the oil when the car is cold, otherwise you'll end up with hot oil spilling onto your hands. You'll also need a pan that holds 2 gal of liquid and place it under the car beneath the drain plug.

Remove the plug, drain the oil, replace the plug. Remove and replace trhe filter. then refill with oil. Do not over fill

Take the car to a car wash and power wash the engine. Do this ONLY with a cold engine. And be prepared to have problems with it starting as water get's into the electrical components. Take some WD-40 with you to spray inside distributor caps, on spark wiring, etc. to get the engine running again.

Then check the engine weekly to see where the oil is coming from.

engine oil has a filler cap on top of the engine,and the gearbox oil goes in the filler plug on the side of the gearbox when i refilled one last week after putting a clutch in one .
