Unfortunately, my first post has to be a problem. 03 Cobra 61,000mls, 2.8 pulley, big bore tb, 3" mac x and muffs, predator tune. For the past few months that I've had her, she's ran fine, until Sunday. Right on startup, thick white/gray smoke that smelled like raw fuel, and it felt like it had a hi-po cam in it, 300-400 rpm idle. It was perfectly fine when I shut it off the night before, and now this. I know for certain that it's being caused by way too much fuel (the oil smells like straight gas) leaking down from the chamber. I just can't figure out why, unless the ECU is toast, or it forgot the tune. Does anyone know if this is possible? I did attempt to pull codes and got nothing back. How would one go about diagnosing a faulty ECU? Any ideas would be greatly appreciated. Thanks in advance. DM
I forgot to mention that part. The oil looks proper, only it smells of gas. There is no oil residue in the antifreeze and the exhaust doesn't smell sweet, as when a head gasket goes. Thanks for the thought. There isn't a reputible dealer in this town either unfortunately. Which is why I'm in need of the advice. DM

Also it may really help to call up SVT themselves. Do a google search for their phone number. Go to Fords website and lookup for buying a new car and it will show you the closest dealership to you.
The water dosen't always leak into the oil first. The exhaust gas is a smaller molecule than the water, so gasses could be entering the cooling system and not vice versa. If you take the coolant cap off after the car has sat for a while does it hiss like a soda that has been shaken? If so pressure is building up in the cooling system = bad head gasket. And coolant could also just be leaking into a cylinder, and not into the oil, which would explain the loping and smoke. Get a mechanic to use a "sniffer" to detect any CO2 in the coolant, or get a/do a compression check.
For those that have contributed to the help, thank you. I finally fixed her. It ended up being a bad FRPS (Fuel Rail Pressure Sensor) Located at the front of the rail on the driver's side. Basically, the diaphram inside broke down and the computer wasn't reading any fuel pressure at the rail and cranked up the voltage to the fuel pump. $90 later and 10 min. to install and all is well. Thanks again to all that helped. DM
