I have a 1994 7.3 IDI 'K' engine in my crew cab dually. It has 90,000 miles.
Problem: I have a fuel leak at the back of the engine which is nearly a steady stream dripping on the starter side of the block. I replaced the rear injector which was leaking a small amount, but this by no means has stopped the leak.
We checked all the fuel lines as well as the pan and lines at the pump. Everything is dry, no leaks. I did find another injector began leaking, but only a very small amount. Not enough to account for the amount of fuel dripping.
What puzzles us is that if I shut off the engine and then restart it, many times the leak will stop until I start it the next time. It almost seems as though there is a switch with an electric magnet that is 'activated' by turning the key off and then back on. But I don't see or know of any such switch on the back of the engine. Sometimes shutting the key off and then back on doesn't help, sometimes it does.
Any ideas as what I need to check next?
I just went to the Pensacola Diesel website and ordered the Injector Installation kit. Since I live east of Tampa, it should be here in a couple of days.
I will super clean the pan tomorrow and wait for the kit to come and then see what happens.
Thanks for your help. I appreciate it!
