i couldn't really hear any thing.
Have you tried revving it with the hood open. w/ the the throttle.
maybe u can find out where the tap is coming from.
if it sounds like a tapping sound, BBs against a wall, like you said earlier. Then you might have a loose or bent valve. B/c that when my KA dropped a valve. It made this really loud tapping sound once it got past 2k, and at constant throttle you could't hear it as much, but giving it gas you could hear it completely.
just another possibilty, which i really hope isnt the case.

The "BB's against the firewall" was the pinging noise I heard at high boost.
It doesn't really sound like valve tapping... but I guess I could be wrong if it's different than I'm used to. I own a KA24 too which has noisy valves.
And no, that's my old Fuji exhaust. The new 3" dual tipped exhaust should be finished tomorrow night.

We traced it to the motor somewhere in the vicinity of the heads when Jayson and I were listening around on the motor.

On another note, I just went by the exhaust fab shop to check out the progress, and WOW... it looks amazing. It only had one tip on but I can already tell its going to end up being absolutely sick...
The exhaust will be ready to roll tomorrow. I'll get some pics and hopefully some sound.

Diesel truck sound is piston slap.. I never heard of diesel truck sound having to do with anythinga bad motor 
Hope you get it sorted out craig. Built motors are usually noisier depending on the piston to wall clearance.

I know that Ryan was telling me it was smoking while under boost before. I'm fairly certain its not the turbo as this is the 3rd turbo that's been in the car, and each has been built with brand new seals. There's also the case of the PCV that's hanging open since it has no intake pipe before the turbo (need to fix this soon). I'm going to keep an ear out if the noise changes after the car heats up.
I think that it's interesting that Jeremy said that Larry's car made the same noise, and interestingly enough his car was smoking and seemed to have blowby issues. I'm wondering if my car has the same issue but I'm hearing its a non-issue? Larry, what came of this?

please remember that you are the one who bought used RC750s and a used Utec for this build i have told you since day one that i think something is wrong with the injectors.
it all comes down to this, you need to step up and upgrade some things on your car. you cant have the fastest car without the right equipment.

I'm going to have to try a few things on my car. There could be half a dozen small things that contribute to smoke that I can fix easily. First things first is to get it back from the exhaust shop so I can dick around with it some.

No disrespect to anyone, but Taurran why dont you just go with Jeremy's suggestions. Afterall he did build your car and knows better than anyone what the problem could be. I build atv's on the side and know what its like working with used parts that might have issues. Why not go with Jeremy's idea and put it in his hands. I know the build took forever and maybe things didnt go exactly the way you wanted but I think it would be in your best interest to let him finish it off. If you supply him with a new EMS and a set of new injectors then he would have to figure this out, because everything else came from him. Once again no disrespect to anyone...
