this what I would try

Rering and throw injectors back in then do a KOEO and check around that Driverside valve area before the Valve cover goes back on see if there any Fuel leaks in that area

Make shure the inject holddown bolt hole is clean

At koeo fuel press would be where it normaly runs psi wise so if you still leaking fuel should be able to see it

 

Benny, Just a shot in the dark , would it be posible that high fuel pressure by passing injectors going to VGT thru turbo and into CAC tube,I know oil lube vgt but with the tune hi psi fuel where else be side to burn or go back to the tank ? brass o rings on both plugs to keep that from happening for back to the tank thoery, so it fills up with fuel mixs with oil thru VGT heavy oil goes to pan lite oil/fuel goes thru CAC ? am I close to one of these

 

I don't think you realize how a Varible geometry turbo works... I don't mean that in a bad way but can only fuel and not oil get to the compressor side by the gallons and not show up in the oil pan?

There is only one oil feed to the turbo.

So there would be no way Injectors fuel /oil mix to go thru VGT turbo, I know it would have to be by the cup fulls and posible code to show up or the truck to run alot diff, thanks sean just makin sence of it all, If we dont ask we dont learn. so I dont get the Bummer lol

 

No problem... this whole thread doesn't make much sense

Hopefully a culprit is found, otherwise, we'll have more luck trying to dig up Jimmy Hoffa.

what the normal cause is, excessive blow by caused by overfull crank case. beyond that thought i really have no cue

 

Since the first day this problem was posted I've been through every plausible explanation for fuel to appear in that side of the turbo/CAC tube and I just can't come up with one. Not even flooding the cylinders with fuel would produce that much fuel in the CAC. I'm stumped.

 

If fuel isn't being burned completely, or even at all in one of the cylinders can it get past the piston and from there into the crankcase, and from the crankcase through the ccv to the cac?

 

But with no fuel in the oil or a rising oil level?



Josh

 

I think that explains it. Everything makes sense if you remove the lack of substantial fuel in the oil comment.

* Fuel has been accumulating over time in the CAC.
* Old oil is changed but because the driver is not thinking about this issue he doesn't inspect it closely for any issues.
* Adds new oil.
* Gets around to doing the injector work etc., but leaves the new oil in the crankcase.
* Then discovers the issue with the fuel in the CAC.
* Checks the oil but nothing is out of order because it's relatively new.

Any takers??

 

Hey in this instance your idea is as plausable as any other cause nuthin else makes much sense either LOL Altho he does state he does know the difference between oil,diesel an water and can read a dipstick.

 

im not tring to infer anything here but, i have seen more then one person that thought they could do when they should have just been teaching.

 

I got a chance to work on the truck this afternoon. Checked the o rings and crush washers and replaced the injectors, torqued them to 28 lbsft. Then I removed all of the glow plugs again and put a pressure gauge on the regulated return. Don't think I've mentioned the ITP RR but it is in my signature. After replacing battery cables I had my son crank it over while I watched under the hood. Fuel pressure came up to 50 psi and fuel shot from cylinders 1 and 2. Did it again with the same result. BTW I just stuck the air box back on the turbo and left off the cac tubes while cranking. That was all I was able get done today. Seems like a lot of work, but what if I switch 1 & 2 injectors with 3 & 4?? I should then know if it is injectors or to start searching elsewhere.

Back when I first tried to restart I spun the motor a good bit and it would not fire. When it first locked I really thought it was a starter problem. I had a post starting 11/5 titled "another starting problem". If you have not read that post it may shed some light on what I've done so far. The starter rebuilder said it was working but showed signs of having been hot. I told him to go ahead and rebuild it. I got it back in and the truck would not crank over. Did that twice. I say all that wondering if my repeated attempts to crank it made a big problem from a relatively small problem.

As far as the oil having fuel in it I will say again I did not see any obvious signs of fuel. I don't doubt there may be some contamination, but I don't think the amount of fuel there equals the amount found in the CAC and both CAC tubes.

Help!!! Any suggestions on my next move?

 

Are injectors 1 and 2 new? If not you could just move 1 and try again and if the problem moves then replace those 2 injectors

 

I see that you replaced all the injectors. It is possible to get a bad remanufactured injector 2 in the same batch may be a stretch but it's possible
