Noise, Smoke, and power loss.
A while back, I noticed that my engine was making a steady "chk" sound that increased in frequency as the RPM's increased. I figured I had a junky injector, so I ran 2 cans of DP. It didn't seem to help much. There seemed to be a loss in power too, 16-18 second 0-60. A month later, I ran 2 more cans of DP, and still, no results. I just kept driving it and I figured that it was 1 or 2 nailing injectors (even though the sound is more of a chk than a nail) and that I would eventually get around to actually diagnosing it. Today, I drove it for the first time in a week (I was out of town) and I noticed that the sound had intensified. A lot. The engine sounded terrible! It wasn't running rough, or even on the verge of stalling. It just sounded...ill. Also, I noticed that when I gave it the first good kick to the throttle, it let out a HUGE black cloud. however, it didn't seem to let out anymore after that.
I'm worried that I might be doing damage to the car by driving it. The noise is clearly coming from the engine block, and if I touch the injector lines, they all seem to give a little feedback, some more than others (this might be normal, I wouldn't know). I'm also hoping that it is not my IP, seeing as I run wvo. Does anybody have any suggestions? Thanks a lot!

Well, I have a two tank system, so yes, it is 100% wvo when it's not diesel. I filter it really fine, and for dewatering, I hold a 55 gal drum at 100-120 degrees for 2-3 days. Now, as far as heat goes, I've been trying to correct my low heat issue, and in the meantime, I have just been carelessly driving it. Well, I guess not carelessly, but I should figure out the heat thing before I continue to drive it. My average temperatures run at about 140. I'm in the process of putting ogether a glowplug heater. hopefully that will bring my temps up. I suspect my injectors may be gunked. In the case that my injectors have received punishment from the wvo, will I have to buy new ones/rebuilt ones or can I just clean them out manually?

If this has occurred recently, you probably will be fortunate and only need to clean the injectors. Like you stated, it might be a good idea to not run on wvo until you have sorted out your heat problems.
It's much easier to "correct" the situation while it's still new.
