Smoke and No Power???

[Agnem]

Don't overlook the possibility that something is going on in the drive train. Brakes dragging maybe? Although I would suspect that would become obvious.

Mel... I did try the dragging brakes issue but thats not it. No hot drums or rotors. Even the parking brake will fully release. The slightest amount of throttle will create sme smoke going down the freeway loaded or even unloaded. o, this is my plans. buy a set of BB injectors. Check the timing again. Do a compression test. Then replace the injectors and setting the timing at the same 9.6 I have now... then test run it and report back here. I never se any blue smoke and I'm very happy for that....

Didn't realize BB injectors were the gold standard even for turbo motors. I have a set of delphi BBs on the shelf that I bought my truck with. Swapped them out for stanadyne D injectors and those seem to be fine

 

[icanfixall]

I'm in no way near an expert on injectors but... The information I have is the golden pop pressure seems to be 1950 lbs. The "G" codes pop at around 2100lbs... So they say. As for the tips, pintles and iternals I know nothing. The g injectors were designed for a high pop pressure and for emmisions standards of the time. So does that mean they are not what we want for hp and economy... I dot know... What I have found out from using two sets of them they are not working buy a long shot. I made one set out of two new Stanadyne injectors. I didn't take them apart but just matched them up for 1950 lbs of pop pressure. Its time to move on to something better. i'm hopeing Russ has the answers. I know Mel can hook me up but I'm stil not really ready for the misters just yet. I would need 2 sets bcause no way could you "find" his out on the road so behind the rear seat will be riding a spare set....

I just replaced 2 slobbering injectors due to excessive smoking. Mine smoked blue however not black. I noticed it got worse as the engine got warmer. Cold it didn't smoke much but hot it left a blue haze going down the road. Since replacing the injectors it does not smoke at all except for when I give it too much throttle then it only smokes black. Love the Moosepump. It's starting to sound like an injector or timing issue. I would check the timing again just incase it may have slipped.

Dirtleg,

I have a similair issue but I get some blue smoke on decel as well. Did you notice any smoke on decel or just going at a steady speed down the road ??

david85 , my supplier only stocks bb codes, it is very hard to get d or e codes, the pump shop says the only difference in the aftermarkets is the letter stamp, the tips and parts are the same. G codes do have a different tip and higher pop. They dont work well with a non turbo pump. Now this weekend I took a set of G's out of a factory turbo truck that I overhauled 5 years ago and put in a new set of BB, didnt raise the pop pressure and he took off on a 500 mile trip. He just left me a message that his mileage was better and the power was unbelievable. Both were complaints since I did the engine. Another black mark in my book for g codes.

OMG! I need bb code injectors!

Interesting.....

One more potential sabotage that was inflicted against the turbo IDI to favor the new powerstroke? Can't help but wonder if it wasn't all to do with emissions.

Funny thing is a lot of guys want to go with G injectors thinking they will make more power.

 

[hesutton]

Gary, how is your fuel pressure? Any change the power loss could be a lack of sufficient fuel supply? Just another thought?

Hello Heath... That thought has crossed my mind a few times. Its something I will be looking into soon. I'm kinda wishing now that I had installed a fuel pressure gauge on the dash when I did the 6 gauge cluster... But thinking along those lines I would like to know the coolant outlet temp from the ratiator. And when the intercooler in installed the *** and tat would be nice knowing that too. I just placed an order for a set of BB injectors...Waiting for them makes me feel like one of those days when the wifey tells me "Not now... Wait till it gets dark"..... Funny ... It never does get that dark now does it....

gary I am working on a gadget to measure just those items already. about 30 inputs will be available.

 

[icanfixall]

Russ... I'm all excited and the check is in the mail..... I want one of those "Gadgets"....

Russ, please explain yourself

Dirtleg,

Diesel Max, I was smoking blue anytime I was on the throttle enough to build any boost at all. On decel the smoke would start to clear up until there wasn't any. It would stay smoke free until I got on the throttle again. At first I thought it was a turbo oil seal but my oil usage didn't support that idea. Fuel economy and power were down however.

Thanks for replying. I'm trying to narrow my problem down and I believe it to a bad turbo seal due to oil usage but I'm going to change the injectors as well since they appear to be the originals. Tearing into the turbo this weekend to check for excessive oil.
