This morning I checked the fuel drain assembly, it is functioning normally, and I double checked the liquid in the valley. It wasn't watered down diesel, it was watered down oil. The truck is collecting oil in the bottom of the valley, about 1/10 of a quart from the four hours of driving. So now I am thinking I have a slow leak at my HPOP.

Interesting thing was that the fuel reservoir would not drain at all until I loosened the filter housing... rough idle sound like a clogged return line to anyone else?

Would the water in the power steering fluid account for the odd steering behavior?

 

If you wan,t to drive this truck you are going to have to go through everything every electrical connection,everything to do with the fuel system,the oil will have to be changed several times all fluids as well,powersteering, difs,tranny,brakes and after that you will still be chasing problems guaranteed

I wish you luck

 

I love challenges, so that is fine with me, as long as you all do not mind helping me along the way, I am sure it will turn out for the best.

 

 

What is a "blow-by"?

 

Blow-by is the compression/cylinder pressure that escapes past the piston rings into the crankcase. all engines have some, diesel's have more than gassers due to the higher cylinder pressure. Excess pressures happen when there are damaged or worn pistons, rings, or cylinder walls

 

so if I were to have gas escaping from my dip stick when the engine is running....then I probably have a similar blow-by situation too? Is a little gas escaping through the dip-stick normal?

 

you might just be missing the seal that keeps the dip stick all sealed up. If it pushes the dip stick out of the tube you have a problem. Pretty much measuring back pressure requires a special gauge and our trucks have quite a bit anyway don't be worried about it. One good way to check is to remove the fill cap on the valve cover. the vapor should be steady. if it puffs like a steam train then you have one cylinder that has cylinder leakage more than the others.

 

Read Tim's post above...we all have blow by. All turbo charged and super charged engine will have more blowby than normally aspirated engine (FI & carburated)

One way to tell if you have excessive blowby is when you find your dip stick poking up out of it's tube a bit...

If you think you have too much blow by....clean your CCV housing. It's right under the intake hose going to the turbo sitting on top the valve cover. But this usually isn't a problem.

 

Thanks guys. After I posted I did some searches through the FTE records and found directions on how to clean the CCV screen and some more information on blow-by.

TJ-I think I am missing the dip-stick seal... I pulled it out this morning and I can see all the way inside of the dip-stick handle.
