Injector question/problem
I just bought a 1993 Ford F250 with the 7.3 IDI diesel at a very good price. The back two Injectors are leaking. I replaced the return line t-valves and it still leaks. What could be the reason I have this leak?

can you tell where its leaking from?
did you lube the O-rings and slide them on without nicking them,do you think?
hey.that sounds like a nice truck.
if this is your first 7.3l read this:
So, chances are, you've all heard of cavitation. But you've heard so many rumors and clear as mud facts you don't exactly know what to believe. If you drive a diesel engine, or any high compression engine, you NEED to read this article and understand it, it could save you thousands of dollars. To create this article, it took years of drudging through stories, facts, experiences, and money. So without further delay.

I would also check the cone at the end of the injector hard line. I had a truck with a cross threaded injector, changed the injector and it still leaked. Cross threading it had changed the angle the line met with the injector and put a new groove in it when the PO over tightened it trying to stop the leak. I had to replace the hard line as well and no more leaking.
