i have a noise comming from around the number 4 cylender if you listen to the line it is real clear its hard to describe the sound. it idels smooth dont miss or anything. is it possible i broke a injector spring or something in the tip and not cause a miss or rofugh idel

 

Not likely, if there is failure in an injector, it would produce lots of smoke as the fuel will not burn properly. Could there be valve train issues in the #4 cylinder area? If you are up to it, swap injectors from cylinder to cylinder. Maybe move #4 to #1, and see if the noise follows the injector, or stays with the cylinder.

 

okay i moved the injector and the noise stayed around the number 4 no soot in my intake so intake valves are all sealing. i cannot hear it in the exhaust side of the motor what about a valve guide?

 

Very possible, how about valve lash? I.e. bad valve train. I am told that 2nd Gens do not require valve adjustment, but I check them anyway. Might not be a bad idea to remove the rocker arm cover, and do a feel/look test on everything.

 

i just adjested them few months back and rechecked them yesterday when i swaped injectors i had one that was a hair off and that was it any way to check a valve guide

 

I would assume if you had a worn guide, you would have oil consumption as well. To my knowledge, the best way to test a valve guide is to remove the valve from the head, and use a inside bore gauge. There are special guide measurement tools as well. But this requires the removal of the head. You could remove the spring from the valve, and give it a very rough "feel test". If the piston is at TDC, it will not drop into the cylinder. I am not sure what kind of tool you would use to relieve spring tension to remove the keepers. All the tools I have seen are used with the head OFF the engine. Have you tried cracking the delivery lines while running to see if the noise changes? Try #4, and maybe a few others as well, and compare the sound differences. Of course, take precaution with this, high PSI.
