2003 LB7 Coolant Loss
OK, I've searched the web for days on this any nothing.
Here is the particulars. 2003 Dmax/Ali, bone stock with a PPE boost valve, 180,000 miles. I changed the injectors for the first time last week-end. While removing them #2 injector cup lifted so I resealed it. All other cups stayed in place. The origianal injectors were pluged up with the typical metalic sludge.
At the same time I put a full set of gauges on it. Normal EGT at cruse ~5-600, idle@ 250 WOT upwards of 1100. FRP idle 6,000 cruse at 2200rmp= 25,000. Boost cruse @ 2200 = 1-3PSI WOT max 23PSI
The engine is still smoking after about 800 miles but is loosing water before and after injector change. I just added some Barr's Leak Alumi-liquid. Smoking is reduced but not totally gone. Radiator hoses are soft all the time. No bubbles in surge tank. No fuel or coolent in oil/no oil in coolent.
I have not yet done a pressure check/moister check on glowplug.Or a balance rate check
My question is... being the turbo is water cooled can the seals go bad and leak water into the exhaust stream causing the smoke? Has anyone else found this to be a problem? I do not think it is leaking in the cold-side of the turbo, I did not find any signs when I had it apart.
The truck runs so much better than it did after the injector change. Its like a new truck.
