Fluid in the Valley???
I have had a leak under my truck and went looking under the hood and found fluid in the Valley on top. Ive had orings on the drain valve of the fuel bowl before. So I thought that was it. The leak continued, and here lately after cranking and driving the truck acts like it runs out of fuel about 400 yds down the road. After turning over a while the truck picks fuel back up and is fine the rest of the drive. After truck sits over night it will do the same thing. I'm thinking about rebuilding the fuel bowl with new O-rings, but asking ya'll what else could be making it act like it runs out of fuel and then running fine after it dies???
Thanks

Best thing to do is clean the valley really well, go for a short drive and then have a look. There are a few places in the valley that can leak. Once you know where it's coming from, we can help you track down the fix.
Low oil levels on these trucks can cause all sorts of running issues. Check your level and top it off if need be.

This is a picture of a pedestal with the turbo on top of it that was leaking at the oil actuator(piston) for the Exhaust Back Pressure Valve. 190K on that engine. I deleted the valve and placed a blank pedestal in the place of this leaking one.
This is the valley with nothing in it. The yellow holes are where the oil goes up to the pedestal and turbo from the Low Pressure Oil Pump and where the oil returns to. The yellow is residue left over from the old orings. If you look very closely at the 90 degree bend in the tubing you will see the drain hole in the back of the valley on the passenger side where all the oil or fuel drains to. It goes between the back of the engine and the transmission and all over the oil pan. The leak can be coming from the pedestal to engine orings or the turbo to pedestal orings or from your High Pressure Oil Pump.
Let us know where it is coming from. Dwayne

gotta love this site. pics are worth so much.
I have a van and can't see much from the front so I can't see in the valley that well. (just that its dirty)
I had a fuel leak, but after getting it checked out, I was told that the valley can hold quite a bit of fluid so it must be residual. depending upon type of driving I would get a drip on flap ground and then sometimes not.
sure can be frustrating

Thanks for the pictures. I will try to get in there this weekend to find where it is coming from. Do you know where I could find a picture of the HPOP? Just would like to see what could be leaking from it?
Thanks for your Help

1. Cover your alternator, cause its expensive to replace (cheapest near me is $180+core&tax)
2. Don't pressure wash.
I missed both of those... saw those notes about an hour after I cleaned mine. My alternator quit the next time I drove my truck over 50 yards. The headlights will get really dim, but she does her best to keep going.
