6nz rocker arm bushings shot?

No, they were old. I ordered a tune up kit for the brakes from Jacobs, but they don't include the solenoids.

 

Yeah, I kenworth only had 2 in stock, but I won't ahead and ordered the 3rd one while I was there. Supposed to be in on Tuesday. I'm a big believer in changing things out together. If 2 are bad, the last one can't be far behind so why not take care of it now, right?

 

There is a hole right on the bottom of the solenoids. That is where mine were leaking. I could see it perfectly by standing on the ground on the right side of the truck while it was running. There should be no oil coming out of there. Now that I swapped them out, I really haven't seen much change in pressure. Maybe a couple pounds higher now, but that's it.

 

Another day, another problem. After a solid week of running (about 4500 miles) the noises I was having are still gone (it's amazing how well stuff works when not being starved for oil!). New problem is that at low speeds, the engine turns into a fog machine between 1300 and 1500 rpm. It is raw fuel smoke. It also does this at a cold startup until it gets plenty of heat running through it. I have heard some people mention head gasket, but it smoked at startup before the rebuild, too. Is there a sensor that could be going bad? Another bad injector? This thing is driving me crazy. I ran with a buddy of mine up E-Town hill the other day and out-pulled his 600 6nz (he has a hot tune). Truck is definitely strong, but it just insists on having issues. Help?

 

The coolant level has never gone down. You can smell that it is fuel burning. Yes, I used the injectors that came with the rebuild kit. It was a platinum kit, so it has a new head, no reman.
