I am hoping to find someone who is near me.

I thought and get video of engine running few hours ago. Here I can hear CHUG but the more louder the near valve cover.

I would say it sound little loud to me but Uncle have exact one he say his f350 more loud.than this.

I told him REV at last min of video you will see blue smoke. You need click this picture to see video.

 

That smoke almost looks like steam and it almost sounds like there is a hissing or squealing noise coming from the engine.

Hopefully someone with a bit more knowledge than I will chime in on this one

 

Hmmm, now that you mention it, I have to agree.
.
It will be helpful to get those codes read.

 

I should have got video. When we left idle for 10-20 mins then come to check rev it end blow tons blue smoke if rev over 1,700 rpm higher the more smoke.

If rev from 1-1500 it little smoke.


I am try find scanner now.

 

Did test.

It hard start so we test glow plugs relay it work good. When cold run it sound misfire for short time before it start smooth.

No smoke if you do slow rev up 2500 rpm. If you hammer rev up 2-3K it blow blue smoke. That sound bad injector?


Did drive test again. It blow brown smoke on hard acceleration.

 

Here video of blue smoke.

If you're reving it before full warm up it will smoke and it sounds to me like you may have a glow plug or more out. Ohm out the first two and last two connections on the under valve cover harness and see if you have any that are dead.

 

Engine was idle warm full. You could see that coolant gauge is up Fully warm.

I did test all glow plugs first with ohm meter but was confused. They not steady it wild volts from .15-.79 then drop to zero. Found 1 that show zero. Then try with bulb light. 1 bad glow plug not light.

But did it sound misfire and hesitance when rev? I could notice little then it go away.

I finally bite and order AE scanner after younger adults who wouldn't help me out so screw them.

 

Well you don't want to test the glow plug with a auto light unless you're just checking to see if the wires to the glow plugs are getting power and if one wire didn't light up then you have a wiring harness issue. A broken wire somewhere that isn't allowing power to that glow plug.

With a voltmeter you want to ohm out the glow plugs and see if they even have continuity. If they come back as 0 then you have a dead glow plug which will need to be replaced and does contribute to your miss on start up.

 

Oh DARN that another $80 for glow plugs. all 7 glow plugs didn't stay at .15-.79 it would go up that number then drop zero. Only 1 glow plug that totally dead no numbers just zero.

I can hear glow plugs relay CLICK and UNCLICK around 10-20 seconds.


Would hook volt meter to batteries and turn on WTS to see if volt drop and up?

 

Yes, you will see a voltage drop to just below 11 volts or there about. Anything below 10.5 means to start.
If you order glow plugs from Clay they are about 10 bucks each. Don't go auto-light. People have reported that they mushroom and believe me, you don't want that. you'll have to dig out the broken part out of the engine or start the engine and hopefully blow it out and hopefully not hurt anything.
If you only have one glow plug out I would just replace the one and I don't recall what they should ohm out at. Maybe someone else will chime in on how many ohms a glow plug should be.

 

We tried today volt when turn on WTS it was 12.55 drop to 11.55 for like 5 sec then it went up 12.40 volt. That mean whole glow plugs dead. We test on other F350 it different result it stay below 11.30 for quiet long like 20 second. But It start good expect mine it stubborn.

Saw motorcraft ZD11 set for $75.

If it mushroom can I hook to drill and spin while pull? I done once on 6.9L that PO put champion it was swell badly.

I'm not sure you can get a drill down there to hook onto the glow plugs. If you're getting intermittent connections to the glow plugs you may just have a loose UVCH connector.

 

Not sure but PO sold that in March and Buyer who bought then gave up and sent to auction then dealer bought then gave up then I bought.


When I tried test with ohm meter. I going make clear for you. When I plug meter to pin on valve cover. It pop up numbers then drop to ZERO. 7 glow plugs did same things it pop up numbers then drop to Zero. Expect 1 glow plugs it stay ZERO.


I not understand how ohm meter. It supposed stay numbers not drop to ZERO?

 

You were clear before. If the reading from your glow plugs is jumping around, then it sounds like there may be a faulty connection between the pin that you're testing and the glow plug itself. Either that or you're not getting a good ground signal on the lead to the meter. To make sure the meter is good, what reading do you get if you hold the 2 leads together?
