Yeah, I suppose the PCM can correct for it, to a point..... If it's just dribbling, that would probably do it.

 

Ok, I did compression check on all cylinders today.they were all. Now my compression guage is and old one that has the rubber piece and not the screw in type, so I am pretty sure all the readings weren't at 100%. Now cranked it over all of them were 75 to 100 PSI. And they were all consistent. #1 and #7plug were wet. It did not look like oil was pretty clear, now these plugs had been in there for awhile but the other six were all dry and none of them were actually fouled, didn't look like and didn't run like. I am going to replace the O rings on all the injectors tomorrow and see were I end up. By the way, thanks for all the help,

 

It's not the o rings but the injectors themselves that leak

 

is there a way to check injector to see of its leaking

 

Pull the fuel rail and injectors up out of the manifold. Verify that the clips that hold the injectors to the rail are actually there, then, just prime the fuel system. (may wanna disable the coil, just unplug it.)

 

You can also clean them using a 9v battery and brake clean

 

Ok, I went and got a new compression tester. All the cylinders were good,holding 120PSI except #6 & #8 held at 90PSI. I went ahead and changed oil and filter again and also changed plugs and wires. I have ordered a complete set of injectors, should be here Monday or Tuesday. I started the truck this morning and it had minimal smoke, not as much as it has been. I may not be a certified mechanic but I think I know what I am doing to an extent. Radiater still full. Gonna see how it runs and go from there I guess. I appreciate all help and any more suggestions will be appreciated and checked.

 

I would check 6&8 either rings are bad (burn oil), heads are cracked (burn oil and coolant), or valves aren't sealing.

 

Yep, 6 and 8 are below minimum spec. Considering they are next to each other....... that really isn't a good sign. May have gasket blowout between the two.
