: : : Fuel knock can be caused by an injector that
: : : does not close properly. I have experienced
: : : this with a Kubota diesel as well as Detroit
: : : diesels. A stethescope might pinpoint which
: : : one is causing the problem. Hope this helps.
: : : : I have a Ford 3000 diesel. Here's what happens: After about half an hour of "heavy" working at full throttle, the engine starts knocking. If I shut it down for 30-40 seconds and re-start, it goes away. The engine doesn't seem too hot to the touch. Could it be running too cold? Could water in the fuel cause this? What else should I look for? (I have already replaced the injectors.) : : What exactly is fuel knock anyway? Is it doing any damage?
: An injector that leaks fuel into the combustion
: chamber causes fuel knock. A tiny speck of
: dirt prevents the injector from closing properly
: and this gives that cylinder too much fuel, and
: this is what causes the knock.
: I believe it will cause premature wear on that
: particular cylinder because too much fuel will wash down the cylinder walls and this leads to
: more expense than replacing an injector.
: The age of an injector has nothing to do with
: whether it leaks or not, my neighbor had a little
: 3cyl Kubota with 150 hours on the clock when
: one injector went bad and it sounded like the
: engine was going to fly apart.

: down the cylinder walls and Dear Henry, I have experienced s similar problem with my Ford 3000 Diesel. Your injector pump is out of time. Set it 22 degress on flywheel instead of 19 degrees. This should help. Good luck. Vern
