k just yesterday going to work didnt have a bit of problem, got to work without a/c again the little plug on top that kicks the clutch in and out needs to be replaced was going to do that today but got to figure out what is wrong with the rest now, ok back to going to work, got to work, then had to go start the water pump no problem then about an hour before dark went to crank her up and she just didnt want to run at all, drained the fuel cannister twice that didnt help any, it idles rough, right at first when i tried idling it up lots of grey smoke, and barely could get it to 2500 rpm second round got it red lined but still lots of smoke, we are out in the middle of a field and as dry as it is here as where it is every where else and sand too, i have to ease in and out of the field but after my truck started this had to have it to the floor but still wasnt right runnin 10mph in 2nd i should be showing in or around 2 grand i know at 20mph it would be close to redline but tonite on the way in i had to idle it up just to take off and had to wind up 2nd to get 3rd and then 4th and talk about slow the most i could get out of her tonite was 70mph that was dropping off a hill with my foot on the floor, temp running right, oil is full, been runnin fuel treatment, got almost home and checked her again and when i pulled the dipstick out i have blow by nothing new have had it since i bought it just got worse, but for some reason i had oil spittin back out of it, pulled the fuel filter when i got home all clean, turbo is whistlin like it should other than noticing one of the bolts broke off from it, but with the sensor on the left side of the valve cover unplugged it idles better but actually taking off still the same acts like its overloading on fuel cause when i got the fuel filter back in tonite and unplugged the plug from that sensor forgot i had the drain on the canister still open and she idled smooth as could be until i realized that and then closed it and still the same but taking off is still the same have to idle it up just to almost untrack her, what could this be any help would be greatly appreciated, if someone tells me it involves working deep within the motor ive already decided to rebuild it like i want but its only got 247k miles on it though, PLZ HELP GUYS , I KNOW SOMEONE KNOWS WHAT IM TALKING ABOUT HOPEFULLY, THANKS lance

 

That has got to be the longest sentence in the world.

 

My head hurts..........., I had to read it 3 times, need to brush up on your gramer skills man

Anyways, what I gathered is that the turbo spolls great but you have lots of blow by and everything else seems to check out but lacks power. Before you get worked up on the blow by issue and setting everything up to requiring an engine rebuild think of this, how often does an engine blow up from starting an engine, especialy when it ran great 1 hour before.

Anyways.......hows your airfilter?

simple checks anyways, check your fuel presure, check you hoses on the "Y" heading into your heads off the turbo, maybe you blew one hout and dropping your boost. Check your simple things.......from thier, pull your valve covers and look for anything bent like rockers or pushrods, all checks out then consider spending a few hours and compresion test the engine.

Before you do any of this, wait for a few more reply's with some other feed back.

 

air filter is in good shape, ill check the other things tonite cause i got to work again today, and sorry guys about the grammer and the long sentence. i went to rising star high school that explains most of it, but having to reread it 3 times ok thats bad ill work on those things then, thanks ill keep those things in mind and check them tonite. Nieghbors sure aint going to like me tonite though, lol thanks Lance

 

k guys talked to a buddy of mine, explained to him what it was doing. he thinks its the CPS, i dont though. my brother in law thinks either turbo or injectors. he also explained to some mechanics where he lives at what my truck was doing and they also think i have one or two bad injectors causing my turbo to turn a blue ish tent i also forgot to mention last nite. but to go 100 miles i used half a tank of fuel where usual its only a quarter of a tank, maybe this helps some more too. but do yall think it might be injectors and also the turbo going out, if so what all would i need to go with a turbo setup from a newer truck like a 99-03 7.3 PSD to go on my truck, already know the injectors ill be gettin if thats the case. i still got to get ahold of a mechanic i know that is good with the PSD and cummins if u got the money he can make them run like a nine day clock and then some. if he says injectors and turbo then thats what ill be doing then. but as far as the other stuff i didnt find anything. but could it be a turbo going out on me or injectors. any help would greatly appreciated and thanks Lance

 

ok, for the turbo, pull you intake pipeing off at the turbo and check for play in the turbo, you dont want know end play and very little side to side(should not touch housing), check the fins if thier in good shape, if you can hear the turbo spool, I doubt its the turbo. Next as for the injectors, if its running fine at idle, I have a hrad time saying its the injectors, it dont go like that, check your HP oil pump.

You need to setup some gauges first to check your presures or put it on a scanner to tell you what is happening or your going to throw a wack load of money down the drain.

Did you check that little hose running to your map sensor, maybe that hose devolped a leak??? That'll cause your truck to run like ***

 

wheres that map sensor at

 

wow

maybe some burnt wiring :

uvc's
vc gasket
external plug

 

Jeez, forgot to mention that.........like he saud, check your wiring at the valve cover gasket and go as fat as ohm out the wiring with an ohm meter on the plugs to check to see if you got some problems, thiers 2, 5 wire connectors for each valve cover gasket, the outside wires are your glow plugs, the 2 inner wires from that are one for each injector and then the middle wire.

So the plug loks like this I 1 I 2 I 3 I 4 I 5 I

1 and 5 are your glow plugs, to check your injectors and ijector wiring, with an ohm metertest wire 2 and 3 for one injector, then test 3 and 4 for the other injuector. You should have 3 ohms and no more.

then like mentioned, check the external wire harness and fallow it to all your plugs and open them up and look for any burning of the pins/plug inside.

As for the map sensor, if I recall its a black box on the firewall passenger side with a hose and a wire connector.

 

k guys checked the map sensor no burns there, the turbo fins check out good, the back plug going to the valve cover on the passenger side back wire where it should plug in, is burnt and the part of the plug is in the plug itself on the valve cover. the red hose for the intake has a slit in it, could this be my problem i mean the plug itself but could there be something causin this and if so what is it. and i am right the turbo is what says garrett on it right the other behind it is the EBPV right or am i wrong again lol Thanks Lance

 

K, I'd replace the valve cover gaskets, looks like you need to replace the plug on the harness or the whole harness, also check the wiring under the valve cover.

My red hose has a slit in it as well, my slit is directly under the clamp to the turbo, I've already changed 3 of these hoses cause of this on 3 different engines. Me personally, the cut is still under the clamp so its tight but knowong I have to replace mine as well.

The turbo will say Garrett, it'll have 2 halves, one half your compresser housing, the other your turbine housing, under neath that you'll have your EBPV.

Anyways, pull off both your valve covers and check your wiring underneath them and replace whatever wiring you need to replace and bet she'll run just fine. I feel kinda foolish with out even thinking about the wiring after reading your post.

 

k i thought the valve cover gaskets on our trucks we could reuse though but if not how much do they usually run though, and as far as wiring or the plug ill replace the plug just have to splice into it though and the red tube i know where theres a bunch of junk strokes though that i can get parts off of though and would the turbo off a 99 or 00 model fit on mine or do i need the downpipe, intake tubes and all and the pedestal, and all that stuff or just the turbo itself thanks ill get to pulling valve covers off tonite have to work once again so dont leave much time to do much

 

If you had to change your glow plugs then yes, you would re-use the cover gaskets but since thier now burnt, thier junk, as for price, I dont know. I just hung onto a spare set of used gaskets for myself that I had laying around so I've not had no intention to purchase.

As for the turbo, why do you want to replace the turbo..............anyways, I dont know if its interchangable

 

leave your stock turbo on the truck...

if you end up needing to buy the external parts for the wiring let me know i got the part #'s you will need for the ih parts man.

 

The gaskets run about 50.00 and the harnesses under the valve cover run about the same. I would not touch the turbo untill you do the wiring first. That is usualy the only thing that goes out on these engins.
