BIG problem!!!!
 
96 psd it started off i was crusing about 50 and the truck lost power and started throwing white smoke. well i stopped and started back up. when i hit about 2200 rpm after that it started making a weird noise kind of like a rod knocking. well i tapped the gas pedal a few times and eventually it went away. i pulled it in the garage and took the intake off and noticed the compressor wheel blades were shot so i rebulit the turbo and added a bd compressor wheel. i finally finished everything up today and all the way to the gas station it was blowing blue smoke so i put some fuel in it and drove it some more thinking it may clear up but didnt so i put it in the garage to notice oil dripping out of the exhaust and pouring from the " return line?" on the passenger side oil pan.

i guess what i am getting at is if anyone knows a possible solution to my problem i would like to know. i am new to all this diesel stuff and right now not having a good expierence lol
thanks [[ChRiS]]

white smoke is due to lack of fuel, blue smoke is usually blowby, if you have oil in your exaust you probably have a bit of piston ring wear, check how much oil it uses and pull the dipstick out while the engine is running, if it puffs smoke you have some blowby. good luck.:rocking:

[[ChRiS]] 12-24-2010 09:05 PM

well it uses some oil.... how do you fix blow by or is it bad?

[[ChRiS]] 12-26-2010 11:14 PM

anyone have opinions? im in need of some help......:argh::argh::argh:

gijohn45 12-27-2010 07:03 AM

the way to fix blowby is replace the rings on the pistons which mean pretty much a complete rebuild of the engine....

well i was going to do a compression test last night but the kit didnt come with a glow plug adapter so i decided its going to the shop tomorrow. one guy said it sounded like the hpop.

Possible an injector is not seated properly. That will blow oil out the exhaust too.

Could be just burning the oil out of the exhaust also. I put a turbo on a 24v common rail and it blue smoked for about 500 miles after it warmed up a bit and after a while it quit. It was dripping oil out of the whole in the muffler. Probably leaked out a 1/2 gallon while it was setting in the shop.

ok well mine like pours blue smoke really bad. i am kind of scared to drive it i mean the turbo whistles a lot louder and builds boost so it seems ok burns some oil... any clue why yours did that? sounds a little strange to me. but it also drips the oil out the exhaust......how bad did yours smoke? sorry for all the questions just trying to figure out whats wrong with it since everytime i ask someone to help me they either dont have time or dont want to make time. and for some strange reason it leaks pretty bad from where the dipstick tube goes into the oil pan is that easy fix? i was gonna do a compression test today, but the tester seems as if it wont work.

We had a truck at work do this and it was an injector that stuck open. I wouldn't drive it anymore until you figure it out. It cost us an engine because it melted the piston and scored the cylinder.

Sounds like you have a cracked piston. While its running remove the oil fill cap. Flip it over and set it down on the top of the fill tube. It will vibrate off, but it should not blow off.

Oil out the tail pipe is blown turbo or too much crank case pressure pushing oil out the turbo seals.

White smoke is RAW fuel... Ie too much fuel.

Blue smoke is typically oil related

Black is fuel.

White can also be coolant, but is also accompanied by a very sweet smell, where as fuel will burn your eyes.

PHPDiesel 01-10-2011 04:44 PM

White can also be too little fuel, Joe.

I've seen it with dead fuel pumps.....
Crank, crank, crank..... white smoke haze out of the exhaust. Not enough to combust. Granted, it doesn't smoke very long.....15 seconds of cranking (not constant) and it's done smoking at all.

well i just rebuilt the turbo so im not thinking that could be it.... how do i tell if its an injector stuck open? i bought a compression tester but i cant get it between the valves...:argh::argh:. just need some help i appreciate all of your imputs anyone here from indiana wanna help me out? lol

---AutoMerged DoublePost---

so what if the oil cap was to blow off not vibrate off? i havent tried it yet but if i have time tomorrow i will.

[[ChRiS]] 01-14-2011 12:25 PM

well good news is i took the truck to the shop this morning and i started it up and he said it had to do with having too much back pressure. what would be causing this and how can i fix it?

97dieselnewb 01-14-2011 01:19 PM

get an exhaust... you want the turbo (from what I understand, chime in if im wrong guys) to have the same amount of back pressure as boost that it's creating, so it runs 1:1 ideally. Our trucks down pipes are very restrictive, and the restriction of exhaust gasses will build up back pressure, so I would start with a more free flowing exhaust


But on the same token Id get a second opinion because everyone one here with a stock truck, like yours, would be having the same or similar problems if it were directly related to back pressure and back pressure only

---AutoMerged DoublePost---

to make the turbo thing make a little sense, it helped me, the turbo will create its own back pressure thats why you can run straight exhaust on these trucks, with out harming them. So, open it up as much as you can

[[ChRiS]] 01-15-2011 04:12 AM

well i told hom to keep it and see if he can figure out whats causing it and how to fix it. as soon as i get it back its going to the exhaust place and gettin 3 inch downpipe into 4 inch tubing to my 8 inch stack. that should open her up:tu: i appreciate everyones help and will let you know the solution to the problem as soon as they tell me. hopefully its not too expensive.

97dieselnewb 01-15-2011 12:21 PM

Don't let a muffler shop over charge you the DP on line is about 100 bucks or less shipped, I like to support local shops and the muffler shop here wanted 225 for a mbrp DP. So obviously I had to pass, do you're homework

[[ChRiS]] 01-15-2011 05:24 PM

yeah i can get a 3 inch shipped to my door for 100$...... got the truck back today and they said they had a guy from ford come hook a computer to it and said the turbo had something wrong in it causing it to have too much backpressure and blow oil out the exhaust. ughhh im getting sick and tired of this turbo bs.

97dieselnewb 01-15-2011 05:28 PM

But you know what it is

[[ChRiS]] 01-16-2011 02:07 AM

yeah thats the good part. im just glad theres not something majorly wrong like bad rings or heads lol.

97dieselnewb 01-16-2011 12:13 PM

Yeah, that'd suck... At least the fix to this is a performance upgrade :-)
