need help asap
 

2004.5 6.0 running really bad. Using alot of fuel 1/4 tank for 50 miles, no power takes miles to reach 70 on a flat road if I go up hill I slow, I hit an overpass at 70 I slow to 40 or less regardless of throttle, idles horrible, shakes while driving, belching s##t ton of dark black smoke. Had a egr cooler delete put in back in September was the egr valve supposed to have been removed also? Please help asap only vehicle I have to get to work and my wife is pregnant and has to travel 40 miles to the doctor once a week.oil pressure gauge shows good batteries are good.hard warm starts cold starts not too bad but still not right.any and all help would be much appreciated.thanks

Do you have access to a scan tool. What other mods do you have? Is your air intake clear? If you already know this just ignore the next part. The black smoke is unburned fuel normally too much for the amount of air put in. Does your turbo surge? I just had mine surge, my veins were sticking and I still didn't get any real smoke to speak of but I had no power and couldn't get over 2600 rpm but I had a combination of problems

No access to scanner. No other mods that I know of. New air filter turbo seems to make a kinda of pulsing sound while driving and loosing power it'll make a make a muffled pop sound some times and the motor cuts out when it does it.the turbo is during a lil oil when I took the breather tube off yesterday.

You really need to find a qualified shop to take a look or buy some type of obd2 tool. It'll be required to do much of anything with your truck!

I would probably take it to an auto parts store and get them to check the codes. They will tell you what they are but write them down anyway and look up those codes. You might be out a turbo on this one. I think what you call pulsing is what I call surging. Had it surged on occasion before this?

Autozone scanned and only found temp sensor bad no other codes. The pulsing us the best way I know to explain it.almost like when you roll down a window on he hiway and iT makes that loud 'pulsion'

Pulsing noise sorry my phone is apos.it does this all the time for a couple months

My first look would be at the turbo, also check all the boots and look at the intercooler. Other members might have some other advice as well

They found a fault code related to a temp sensor. That doesn't mean the temp sensor is bad!!!

It was bad the plug was broke off when I had egr cooler delete installed I got a new one though

Cool deal, too often have folks come in and say "this is bad, the parts store said". Each time we have to explain why it must be diagnosed etc.

I always double check suggestions I don't trust parts stores all they want is my money lol how do I check boost amount my truck doesn't have gauge.if the turbo isn't trying to lock down or anything could I rebuild it

Usually the veins will stick. Also have you checked your oil? Does it smell like fuel? Is it high?

What would it cost to buy a rebuild kit and is it something that can be done with basic hand tools I am mechanically inclined just never owned a diesel before

If you do it all I can say is it's not going to be fun. The back bolt is terrible. You might want to pick up a chiltons or hay be manual if you want to do it. Not sure on the kit cost. Mine was under warranty and the others I've done were for friends so they bough parts

Oil is ok gonna change it anyway though its over due a hundred miles are bosch good oil filters? I've heard certain filters don't work right in 6.0s

I'd get a motor craft it's your safest bet

Would a weak turbo cause all of these issues including the miss?

---AutoMerged DoublePost---

Prison, what all issues did you have that you spoke of earlier? My truck will get rpms up to whatever but just falls out.

My truck had a high pressure oil leak so I lacked power there and the turbo seals were shot and the veins were stuck. A couple weeks before it happened I had a surge going uphill at 50 mph on cruise two days in a row. It was fine until I was accelerating and heard a pop. It sat a month before this started. You've definitely got enough fuel though with all the smoke. A miss sounds more like a bad injector

What us a quick easy way to check hpo system for a broke white bit I have an air compressor but where do I plug it to and how much psi do I apply for how long?

---AutoMerged DoublePost---

White boy not bit lol

ICP port on passengers valve cover side. Remove ICP sensor and plug it with 3/8 male flare like this one

Would I get this at a hardware store?

Coreection... I thinknis 1/4 male flare. Yes. I would look at Lowes store. They got more selection

Awesome info. Do I need to power ipr to close? Do you have a link or instructions on how to do this test?

Yes. U can wire it from a connector. I have to look under my hood. But you can search for the instruction from Google.

Ok thanks for the help. I'm actually excited and anxious to try this out. I've always done my own work but this is my first diesel. Hopefully it will be warmer tomorrow I hate mechanicing in the cold. Can't wait to dive in I love the challenge. I'll post what I find and any questions I may have.

Haven't checked hpop yet but I noticed today I cranked for about a good 25-30 secs and my oil gauge never nudged but when running it shows normal.bad lpop?

Could be low pressure pump. The gauge in dash is engine oil pressure. (Well isn't really gauge ) that feeds engine oil and feeds hpop with oil. If it isn't feeding hpop will not fire injectors.

Its also dying when I put it in gear it idles ok.soldered ficm this weekend runs lil better but not right.any advice on that?

You need to know oil pressure and if you have a leak. Aftermarket oil filters don't seat check valve in filter housing, tubes feeding oil to rails can leak, dummy plugs in rails can leak. Injector to rail connection can leak. You can guess a lot but to fix it you need to know pressure is good first.

I changed oil this weekend and the dying when I pit it into gear started almost instantly.i used a boschfilter do they have a history of being a pain on 6.0s?

Motorcraft or fram only. The filter is too short and allows oil to drain back into motor instead of pressurizing system. Try filter first

Put in mototcraft filter a couple hours ago still the same.the plunger didn't want to push down by hand very easily at first I didn't see anything to hinder it.I'm at my end with this truck!i love when it runs right but every time I fix it some thing else happens.

Sorry bout all the questions guys just need help.this is my first diesel and I don't really have the money to put it in a shop plus I don't trust shops.i lost a damn good blazer to a lazy worthless mechanic trying to permatex a set of head gaskets I gave him the gaskets when I dropped it off is the bad thing.

That stinks about your blazer. . . I wonder if plunger seal is damaged ? I'm the only wrench turner on my truck. I sold snap on tools for 4 1/2 yrs, saw how shoddy some guys are. I'm amazed some are still in business. . But I saw some real class guys doing good work for fair price too . .

---AutoMerged DoublePost---

Bulletproof diesel sells a nice monitor for $165? I like the display and data advertised, can't wait to try one! It may be good idea for you ? Supposedly gives you all the important parameters of your truck. I'm thinking money well spent if its as advertised and can remain in place to keep eye on your motor.

Yeah I've come to the conclusion I need to get a scanner to do anything else.I'm not gonna throw parts on it.i tried every thing free or few dollars cheap that I could hoping to fix it.guess I'm gonna have to work extra hours and save done cash lol

I noticed when I took the old filter out,i dropped it on the ground Sunday then tapped it today to see how bad it was clogged, a small ring bout an inch in diameter fell out.it has four lil feet on it what is this? also I've checked the filter twice today and both times the housing was dry and the filter only looked damp not soaked in oil first time was only 5 mins after I killed it

Sounds like an adapter for aftermarket filter. . . You definitely need motorcraft filter and stock filter cap. Your truck will probably run again.

I put in motorcraft filter yesterday the cap is napa got a motorcraft cap coming tomorrow.is it possible to remove filter housing and clean it up? What would work best? Also would rebuilding the turbo be something I can handle?i think the vanes are sticking a lil.it has a bad lag and smokes black then it takes off ok

If you are careful and decent mechanic you can clean turbo. I would see prev posts and stickies up top of page for good advice on it. Some guys do it as a regular service once a year. I would recommend as it doesn't cost more than new gasket and some anti seize and will let you see if anything else is needed in there.

Ok.if I have to replace hpop what is a good brand and would it be good idea to change ipr also while I'm down that far?

You getting way too ahead of yourself. . . Try cap and filter first. If you get down to pump you may as well do some more items to bulletproof your truck. . .

Cap did nothing.my new neighbor owns a diesel mechanic shop he's gonna scan it for free.he thinks hpop also gonna let me loose in his shop to work on my truck.so I'll have access to the proper tools.hopefully I'll find the tool drawer with the money in it to buy the parts I need.lol

And the turbo issue was an easy fix.the wires for the vane control were frayed and shorting out luckily nothing burnt up from it its spooling up like it should now.
