I,am leaking diesel in a ford f250 7.3 litre diesel turbo powerstroke. It is coming up toward the passenger side of oil pan. It is a consistent leak that seems to getting worse. Also there is a power decrease could this be because of this and where is the leak coming from?

Howdy,


Most likely your issue is going to be the O-rings in the fuel/water separator drain valve located under the "powerstroke" cover on top of the engine. Look for a yellow handle on the pass. side on the back side of the fuel bowl. Open it and close it a couple of times, it may stop leaking, it may not. You can get the entire drain valve replaced for a chunk of change, or if it you're able you can just replace the o-rings themselves for just a few $. Your ford dealer should have both the valve and the o-rings.

Sounds like a fuel line. trace the fuel line from under the truck on the driversside should go up the back of the motor. the fuel line is probably spraying over to the passenger side of the motor. yes this could cause a power loss.
