03 Loaping and white smoke.

[JWesthoven]

I know I know this screams injectors. let me start by saying that i have exploaded my hellfires before right after i first got them from what i am assuming too high of rail pressure. i sent them back to don to be fixed and since i got them back in i have had two pulls on the truck and a hundred of so miles on the street. both with the MP8 off, rail pressure on the smarty on 2 and no added rail with the PMCR. the truck seemes to run great and pull hard then all the sudden it looses all power and starts loaping from 500 - 1200 RPM's with white smoke. im not getting any diesel dripping out the exhaust like it was the first time i broke them. when it did it on the street i didnt have to shut the truck off. i just reved it a couple times and it went back to normal. after the pulls i had to shut her down and restart it a couple times for it to quit. what do you think is going on? could they be sticking open? so far im not a fan of F1. i had this same set up on my stockers and even tho i SUPPOSEDLY had 4 cracked bodies they never gave me one problem. they cost me 300 to fix on top of the 1700 i paid for them. should be doing better than that. im not sure that their the problem this time but i dont know what else it could be.

It does sound like sticking injectors. I don't know of anything else that would act like that.

thats what was thinking. i ran a tank of fuel through it with about 150 gallons worth of fuel treatment/injector cleaner to see if it helps. i will know this wknd when i pull. every time it happens it always throwm PO336 code and it says checksum error on the smarty. i have gotten that before so i thought it was a normal code. could me running the timing set on 18 degrees affect anything. before i got my injectors back i used the R37 remote with the tst and you couldnt adjust timing. now i got the PDA so i am new to timing controle as all this is happening as well.

Hows the oil level?

Check TQ on cross over Tubes, and install correctly, if one acts up it will cause the conditions posted.

Are you running the timing on the TST at 18*, along with the smarty?



FWIW, I wouldn't run any timing from the TST with the smarty. Mine starts rattling any time I add more than 3 degrees of timing. With dual pumps, I would also run stock pressure on the smarty. At least til you get this problem figured out.

oil level is good. thats why i dont think it is a cracked body. . TWest. what is the TQ supposed to be on them. I never used a TQ wrench when i put them back in so very well could be too tight. Assuming you need a special torq wrench to do this?? Smarty on #8 with no added timing. i use only the TST for added timing. stock pressures with smarty and TST. MP8 turned off for timne being. I cant seem to get it to do it with when i am running stock rail pressures on the street. I will know saturday as im going to pull with stock pressures to see if it does it. My rail is not capped either and have never gotten a relief valve code for it opening??
