My 96 has 188K on it and has never had the injectors messed with, as far as I know. I have not touched them since I bought the truck, about 3 months ago. After pressure washing the grime off the valve covers and top of the engine, I noticed what seems like fuel leaking from someplace around 5 and 6 injectors. It's not bad, but wet around them. The truck runs great.

Is there anything that normally fails in this area that I need to replace, washer, O-ring, etc.?
Or do I have a bigger problem to investigate?


Thanks,
Chris

 

maybe check the return lines, bolts and seals on each injector. I have seen the lines get rusted out before.

 

My '95 was leaking from the injectors. I took them out and replaced the copper washers that go between the bottom of the injector and the head and re-torqued the injectors. No more leak! I replaced thr copper gaskets on the return line while I had everything apart.
