if you want good, clean power, i'd be looking at a 6x10 VCO. with your setup, they'll make just as much power as the 5x12s and they'll be much cleaner.

the 5x12s will be capable of more power, but you won't be tuning for MAX power from the way it sounds.

 

Every truck reacts different but from my exp., I wouldn't hold a lot of hope in cleaning up POD haze, as I said the only real improvement I saw was by turning down the full fuel screw, and even at that it was a minimal improvement. They make decent(if not hot n dirty) power for the $ but there are much better choices out there...at least nowadays, when I bought my POD's it was about the only sub-$800 choice to be had, thankfully the diesel market has seen the need and responded with better priced solutions.

 

. 6x10's?? In a VOC? Who carries these? Link?

 

VCO, yes, The Hungry Diesel

 

6x10's are usually honed stock injectors.

 

Hey, all, update with a question- so I invested in DAP 5X12 VCO injectors. Talked with the folks at DAP, gave them my situation on the POD haze extreme at idle and my current driving style of stop and go Bay Area commuting. The 5X12's came highly recommended, as a clean burning injector along with mild power for passing on the freeways and avoiding these nutty Bay Area commuters who never signal at all. Anyway, while pulling out the POD injectors, I noticed #5 was soaking wet, I mean from the hold down nut to the tip. All the rest were bone dry, with the tips blackened by carbon which I assume is normal. Mind you, I haven't driven or started the truck in over a week. Can anyone clue me in on why #5 was wet, while the others bone dry? I've got nothing better to do in my trailer, so I have done a ton of reading on injector types and conditions. One thread posted a wet injector, and answers back were a possible cracked tip? Could this have caused the bad POD haze? Truck always seemed to run well in the past, except for the smoke. Maybe I've been clueless, and these VCO's will open my eyes on how a the trucks suppose to perform. Keep you all posted

 

The wet injector could have been caused by a dribbly injector or it might have been seeping from where the line attaches. If it was the line causing the wet it's prob not why it was hazing so bad, BUT if that stick was dribbly (not seating fully, very low pop psi) it could definitely be the cause of the mad haze. Either way, hope you love those 5x12's and plz be sure to report back on how clean they idle

 

Chrislib, thanks for the insight. Real weird how just one was wet. Anyway, just got done getting the engine compartment cleaned off from the splash of injector bleeding. It still has a slight stumble, very slight. May still have air. I mean I cracked those things 3x each, slightly first to spot bubbles. If bubbles were seen, cracked open s'more till mist spray was shown. Even got engine to stumble on some that I cracked open too much. Gonna take a 35 minute drive to Costco for some groceries, all the while I plan on pulling over a couple times on the way to check for leaks. The haze, if any, will be seen on my side mirrors. Hopefully it is at least 75% haze free. I'm already telling myself to expect some haze, but nowhere like the POD's. Will report back in about 3 hours

 

Had to stop at the local chipotle on the way to Costco 20 minutes away. Made 2 stops so far. So far no fuel leaks so that's good. I was at a stop 10 minutes from where I installed the DAPs, and noticed a slight haze at idle. At the chipotle parking lot 10 minutes further, no haze whatsoever. So, that's a good thing! Now, changes that happened with the DAPs from the PODs- 1. Idle is now almost 100 RPM's higher. 2. Power seems slightly less with these DAPs. It's hard to put a description to it. It's as if the power comes on later at acceleration vs the PODs that seemed to give instant power when you put your foot on it. I'm ok with the change. 3. When I punch it at low boost cruising, no black cloud. With the PODs, I would resemble an octopus when I did that. Again, my goals were to lose the haze and hopefully up my fuel mileage. So as it sits now with my VE, never messed with it at all with the injector swap. I researched my notes from past, and saw that I had the Starwheel under the AFC all the way up with the stouter spring from Hungry Diesel. Still running the M&H spacer, along with the Smokey Pin. Will post one more time tonite to confirm the haze situation

 

You were at Costco on Stanford ranch in Roseville today? we were at Sprouts next door about 2:30.

 

Lost some boost with these VCO's. No worries, as I'm learning that the settings on my pump I used for the PODs I cannot reuse for these DAP injectors. I went ahead and opened up the AFC, and cleaned the power pin and will rethink if I want to stay with this Hungry Diesel spring((very, very stiff) or go back to the spring that came with the smokey power pin(stiffer than stock, but lighter than HD spring). Also, I need help with this one- looking down the AFC port I see the pin pop out when I gently stroke the throttle linkage. I release the linkage and pin stays outward. Is it not suppose to pop back in?

 

It has to be pushed back in. It is just a loose pin sliding through the housing (and an o-ring, of course), between the AFC lever's foot inside the pump, and the AFC control pin.

Please keep us up to date with how things turn out as you tune the truck.

 

. LOL!! I wish I was at THAT Costco! No, unfortunately, I was at the one in San Jose. Didn't go home this weekend as I have a dr appointment Tuesday am at Roseville Sutter. Didn't make sense to drive home, drive back to bay, then turn around and drive back to Roseville, then back to bay. I know you and I still have to meet, Mark

 

Thanks, Alec, for the reply back. Did a lot of reading on that pin last night, and found out that at times we have to push that pin back in manually in order to drop in our AFC power pins. Yeah, this will probably be the 1st time I truly spend the time fiddling with the AFC to properly tune the fuel. In the past(remember, young and dumb), I just did the bare necessity required to fix and move on. PODs, yeah, lots of smoke, yeah, who cares about mileage LOL!! Today, I will clean out the AFC port, re lube my power pin, and crank down the star wheel 1 whole turn for now and test drive. What I'm looking for is that quick surge in boost, but not so quick that it pours out octupus blackness. I've got this country road mapped out with minimum traffic and a rest spot, and being that I've got nothing better to do today, I will keep cruising up and down that road, readjusting the AFC settings till I settle on power with minimum smoke. My plan also is to not even mess with the full power screw, unless you all advise different. If there is anything I am overlooking, do tell! The AFC star wheel setting I had set for the PODs, cranked all the way up, worked for those injectors, cause those things just poured out fuel. These 5x12's are a different beast. I think I'm going to like these DAPs once I find that sweet spot. Curious to know if anyone has a pic or actually knows the amount of coils in the stock AFC spring. I have 3 springs- the Hungry Diesel very stiff spring which I've used the last 2 years, the spring that came with the smokey pin, and the stock spring. Between the latter 2, one has 3 coils, and the other has 4 coils. I did not label which one was the stock spring when I pulled it out in 2004!!

 

Hey, Alec, back on that pin that pops out and rides the power pin. Under driving conditions, that pin slides in and out on its own, correct? I've looked at cross sectional views of the VE that BC847 posted on one of the search threads I was looking at, but I'm not understanding what would pull the pin back inward on its own. Is it the actual shape of the stock power pin or aftermarket power pins that cause it to go back inwards, as the diaphragm retracts upwards in a no boost situation?
