so last weekend I installed new coil packs, plugs, wires, and valve cover gaskets since they were leaking badly and coating my 02 sensors in oil. I did this because I've had a lot of misfire codes for over a year they go on and off, but mainly because the valve covers were leaking oil and started giving some bad misfires. Once I got to the injectors the o rings were bad and the hard plastic washer on the ends were broken on one injector. I had them sent out and cleaned like 3 years ago so this weekend I opted for some new ones. After everything was installed she started up fine and ran smooth for about 50 seconds and started stumbling, giving off white smoke and then stalled. Each time I try to start her up she would barely run and then stall, the smell of gas was powerful. on the passenger side at the bottom of the headers connecting to the y pipe gas is flowing out. Any ideas?

 

2003 discovery, head gaskets are good and cylinders are already sleeved

 

Either the gas line is not firmly seated under the coils or one of your new injectors has a torn or awkward o ring. Either way you will need to take the upper intake off. I bet it is an O ring. I wouldn't drive it or even run it. Sparks from the wires can ignite the gas.

I've had the same problem.

 

Ok I'll start this weekend will I need to replace the upper plentum gasket again? so today I tried to give it another start and she wouldn't turn over and really quickly I smelled gas and a couple more tries the gas came back out of the header again I press the Anterra button in the weirdest thing happened nothing on top of that my hazard lights went on and wouldn't turn off. So I took the key out and put the key back and tried it again Pressing the intera button again hazard lights went off but still won't start I'm pretty low on gas but the gas light is not on and plenty of gas is coming out of the header gasket the lower part of the header gasket. The first day when she stalled it seem like she was starving for gas yet it was coming out of the header today she wants to start so bad but just won't turn over I'm thinking gas isn't getting fed I don't know? One step I may have missed was torquing the fuel rail down to 6-7lbs I just got a really cranked it by hand do you think too much pressure could've blown the ring on the injector or injectors?

 

No gas means you disturbed the inertial switch. It is the black switch on the firewall, passenger side. That keeps it from starting and your hazards go on so the coroner can find you after a wreck. Just press down on the switch and you should be good to go. It stops the fuel pump when you are in a wreck. If they are still blinking, unlock the door with the key (even if it is already unlocked, do it again), put the key in the ignition at the second position (just before start), leave the door open, and disconnect the battery. Wait a few and reconnect it.

I have removed my upper intake and fuel rails on river engines probably a dozen times and never torqued the fuel rail bolts. I just tighten them. I don't think you did anything wrong.

Is the gas coming our of the intake area or over the transmission? I'm beginning to wonder if your fuel line isn't disconnected. It sits under the coils.

 

No it's leaking in the passenger side coming out of the bottom of the exhaust header gasket so it's flowing down the header.

 

Wow that is a serious leak. Serious!

Has to be an injector. Pull your oil dipstick. Does your oil smell strongly of gas? If so you could have a stuck injector. A stuck injector ruined a rebuilt engine of mine during break in. Hydrokocked and bend a rod, destroying a piston. I'm lucky it didn't blow up.

The only real questions are which injector is the issue, is it leaking around the o ring or shooting out of the bottom of the injector, and whether it has thinned your oil.

If the oil smells normal it is probably the o ring. If it smells like gas (strongly) is the a bad or stuck injector.

That has in your exhaust will eat your catalytic converter and open a whole new can offer worms.

I guess it is remotely possible that you have a bad spark plug. Is your Disco showing a misfire?

 

I'm in the middle of a move in the upper Plenum right now and the oil does smells strongly of gas so I'm hoping it's just an injector and hopefully not something like a crackhead but I had no issues before doing this job

 

OK I just noticed the passenger side coil pack the harness plug came unplugged from the coil pack somehow during install or whatever it came unplugged you guys let me know what do you think I should do do I keep tearing down to get a visual on the injectors that are brand-new with brand-new O-rings also do I drain out the oil that is now have gas in it I'm gonna stop Till I get some advice

 

Wise man to stop. I hate being the only guy commenting here because I don't want to be wrong. But the reason I know about the oil in the gas is that I had a stuck injector. If the coils were not plugged in you'd still get gas but no spark, which is the same thing as a stuck injector (times four!). So, yes, I would stop where you are, drain and replace the oil (and filter), plug in the coil connector, and fire it up. With any luck you discovered the problem and will be immediately in business.

When you drain the oil, take note how thin it is. Mine was like dirty water ( that smelled like straight gas) thanks to the introduction of gas.

And please be careful around it. If the oil smells strongly of gas you should treat it like gasoline.
