Diesel smell comming into cab with an apparent leak under truck. Noticed vapor and drip coming out of tube hanging down behind fuel filter (2003 5.9). Oil level looks good, not trans fluid? Is there a high psi pop off valve or something there. Going to start tearing into it now to keep the young ones safe from fumes...It's the family daily driver.

Make sure the drain valve didn't get bumped, cap is tight, o-ring is leaking, #4 injector line isn't cracked...

Fleetguard Introduces Enviroguard Open Crankcase Ventilation System for Class 5-8 Vehicles. Enviroguard(TM) systems provide superior aerosol filtering of crankcase emissions, commonly known as blowby. According to John Clevenger, Fleetguard's Director of Product Management, "Blowby is the condition that occurs when high pressure gases and oils escape around piston rings. The oily mist attracts dust and airborne particles, resulting in an accumulation on the engine and on the surface beneath it. This condition increases the clean-up required in the engine compartment. It also results in unsightly oil drips on highways, parking lots, garage floors and driveways. Enviroguard(TM) eliminates this messy oil drip problem for good."

This is the problem... 3 Big chain parts stores do not carry it nor can they get it sooo it's off to the dealer at just a little over $100. This seems a bit much but it is what it is.

Check the banjo bolt on the return line at the back of the cyl. head. Mine was leaking there, just had to tighten the bolt up.

This..
The 3 most likely culprits. Have had a pinched o ring, not tight enough filter cap and # 4 inj line on mine before.
