So I was coming home from being stateside late last nite bored, (just under 2000 miles in 2 days), and tired and ended up in a race , just to amuse myself, with a little foreign sports car of some sort. After impressing myself with atop gps speed of 121mph, I slowed back down to my cruising speed of around 77mph. About 5 minutes after the run, I pulled into a coffee shop for 5 minutes and when I started my truck, it had a knocking noise in engine. Drove another 150 miles to home, never got any worse. No bass pressure, no filings in bass, besides the noise, it's working perfect. It sounds louder on driver side close to half way. Gonna pull her apart on Monday. What do you think? Donald

What all do you have for gauges or chips or stuff like that? What was all their max readings if you do have some?

Edge juice with attitude, hot unlock, on stage three, I think it's set at 1500*

Well 1500 will definitely do it. If it's a continuous knock I would definitely tear it apart and see what happened. Post some pics of your findings :thumbup2:

Another hour in the morning and we'll have the motor out. Prediction of my good friend mechanic is a wrist pin bearing. Hopefully by dinnertime tomorrow, we'll know. Donald

I know I really need to put the $ out and get a bigger turbo!

Where on the injector do you look to find out what's in her size wise?

Thanks Mopar, I'll have a peek tomorrow

Got my injector #. It's 0432193629. What size are these? Donald

---------- Post added at 06:42 PM ---------- Previous post was at 06:36 PM ----------

Got my engine tore down. It was the #5 piston scuffed. Sorry guys I can't do any pics for you rite now. My mechanic couldn't believe it was scuffed with no bass pressure. So off tomorrow to get my block bored and head checked and crank polished and $$$$ all from my own stupidity. Had I spent $1600 two months ago for a bigger turbo, I wouldn't be doing this engine job rite now, and I new better too. Donald

Well, if I,ve got stock injectors, then I've got one hell of a smoky truck for stock. This thing is dumping its boost on level 3 at 28lbs boost and if I put it on level 6, hot unlock, it will smoke so bad, you can hardy see the car behind you. Now I'm puzzled. Donald And it pulls hard too

Anyone want to verify my info... :shrug: As for the smoke... Heavy black smoke means there is excessive fuel to air ratio. Do you have a boost leak? I just lost a manifold bolt not to long ago and found that 6mm bolt hole can really drop boost pressure. Is the IAT temp sensor correct? I've seen where a IAT sensor reading lower temp create some dark clouds... Ummm... I left my IAT fooler on from high idle and boy at 26*F worth of manifold temp it can dump some thick black clouds! So check you IAT sensor with a live data tool it should read roughly +40*F over outside temp while cruising... Or the same temp of the coolant in the morning. Wastegate hung up and not closing completely? I seen a few report of P0234 code and found the wastegate frozen. Is it possible the wastegate is hanging up and not closing completely?

l'll try and check things out, but if my waste gate was sticking, would she still dump the boost at 28 lbs. Or if I had aair to air leak. To me it seems like I'm getting lots of fuel, but not enough air. Especially when I have the power I have plus high EGTs. I'm totally confused

Something to think about... Without my Edge Comp (completely disconnected) and stock injectors with a boost elbow I still can pull almost 25 PSI of boost... Now with Edge Comp on 5x5 and RV275 injector I bury my 35 PSI boost gauge most times... 34-35 PSI of boost... High pyro temps means lack of boost. Lost of black smoke mean lack of boost... If the wastegate wasn't shutting completely it can't build full boost. If there is a boost leak like a gasket or such the boost pressure could be lower.

Well, I think I'm really going to have to give my truck a look over when I put her back together. If I have a boost leak, I can't wait to try this truck without one. I've run duramaxes with programmers and never lost a race yet. My neighbor mechanic has an 02 6 speed dodge with 4" exhaust, otherwise stock and mine will completely destroy it. I do find my truck a little slow to spool up thou. Nothing is ever simple is it? Donald

the body gets re used when injectors are uprated to bigger nozzles. If the injectors are stock they are roughly 7 x 0.0075 Without checking the diameter on the nozzlesthe HO nozzles are roughly 7 x 0.0071RV275 are about 7 x 0.008if you take apart an injector there may be numbers on the nozzle, but make sure you do it in a clean place and don't lose anything.

I have my injectors at an injector shop rite now. He is going to take them apart and clean them. He asked to see if anybody would know the stock#s on the nozzle or any of the aftermarket nozzle #s. Any info would be greatly appreciated. I gotta get this rig figured out before I put her back together. Donald

Well, the only thing he can find marked on them is a P, no numbers, no nothing. Any idea? Donald

I'll see Monday if he can get some sizes off them. I'm think I'm going back to a 12 valve with the inline pump. My head is screwed and it's going to be too much money to put into an old truck. So I'll will be listing some parts for sale soon, 3 month old injector pump, edge juice/ hot unlock, block, crank, etc. I don't know how much work it will be to get the lock-up to work, anybody know rite off hand? Am I crazy going back to a 12 valve? I have an old truck I'm junking is the biggest reason why I'm going with the 12 valve. Donald

It's like 2500 miles away from me, so I that wont work. I found a head for $250 but by the time you got it checked out, I wouldn't be too far off the price of a new one. There's a complete truck for sale, a 98 dually 2wd, asking $2500 I was thinking on calling about. Donald
