Postby cumminsram » Thu Mar 15, 2007 8:00 am

My mid 3 injectors are leaking and I cant quiet tell where it coming from does any one know what could be wrong. The fuel is sitting in the recess at the top of the injector nut. I dont know wether its coming from below or what? :?

Get yourself a can of carb/brake cleaner and spray everything down. After its dry and clean start it up and watch for the leaks.

I've heard that leaks are normal, but if your filling your injection recess with fuel that seems rather extreme.

4 of mine bubble when I shoot 'em with soapy water, but I don't have any visible fuel leaks. I've heard that the copper washer between the injector and head, coupled with age or faulty installation, is the most common cause of leaks.
