Well for about 1 month of use 5w40 shell t6 it almost never used oil. Until 2 weeks it start bleach blue smoke out exhaust on cold start.

Notice that I need pour about 3-4 quarts every 600 miles.

I decided check injector oil pressure it was around 475-480 with Duty stay 9.75% Last month it was 460-470 psi with duty 8.74%

I check cylinder contribution balance they passed expect #8 injector that never go away after replace twice with AE then AD.

Still wonder so I decided look in Cylinder verifoty in Live Date where it tell % how much it is.
1,2,5,6,7 had zero. 3 is 1.2-1.8 4 is about same of 3 8 always stay 3.5-6.9


I notice that when you start cold and acceleration it feel like you had no oil pressure it drain somewhere until it become warmer it stop. Like it flip switch then there power.

 

Injector O rings generally will cause a black fuel filter.

The "flip of a switch" has been used to describe the EBPV releasing, or even injectors starting to fire.

How is your blow by?

 

EBPV is disable it was ANNOY and not safe for me when I need go on highway.

Blow-by been same since I got. Crankcase vent hose is go by transfer case for this reason. If I hook to intake hose it use more. It actually reduce so much. Then 10K miles now it start use oil more.


I going check fuel filter tomorrow possible. But 3 weeks ago it was kinda dark brown but still clean.


Before it start use oil. Injectors were fine you could start and drive no problem. 3K miles on oil now it feel sluggish horrible when cold. Alot blue smoke out exhaust plus new glow plugs/snow plow Relay. It start doing this 2 weeks ago it gotten worse now.

 

What CPS do you have? #8 always reads high on rotational velocity. #3 tends to read high with the newer CPS's. None of your numbers are high enough to cause concern.

Checking the fuel filter is a good idea. Checking your exhaust pipe for any signs of oil, or looking in the down pipe or checking for play on the turbo wheel is another possibility. Since you're using oil, it's got to be going somewhere.

This of course assumes you don't have an oil leak.

 

I'm guessing turbo from what I can understand...

 

I thought about turbo since it develop new issue now.

When you are idle and boost gauge is vibration which I talk to 1 friend with 6.0L he say it not supposed to do that at idle.


Couple times it would shakey from 3-10 psi.

New used turbo supposed coming tomorrow it only had 88K miles I hoping it fix issue. Oh right I order from RiffRaff for Wick wheel and turbo reinstall kit plus new clamp I suspect mine bent from overtight.



On CPS Ford replaced one in July 2010 by Previous Owner. I got this truck in June 2011. I replaced cps in Oct it was cause engine cut off when it rain. I got new CPS It grey with purple o-ring. It was $23 from Superior Turbo shop in Detroit.


I will check exhaust pipe to see if it wet. I think I plan pull valve cover and change o-ring on #4 injector to hoping if it bad o-rings.


I get video of cold start tomorrow it really bad. Alot blue smoke.

 

Forgot to add I notice white smoke on heavy acceleration it was more likely to be grey color since I was looking at passenger mirror.

Today it was actually DARK blue or light black smoke. It wasn't definably black look like blue.

Its not injector O rings...

 

I hope because it had 8 new injectors 0-rings.

Wouldn't IPR duty/ ICP pressure show huge drop on cold start when o-rings is loose on cold engine?


Going to peek turbo to see if oil inside.

 

It would have to be extreamly bad, and more then one to cause an issue like your talking about.

Your issue is your turbo... 99.95% sure of it.

 

You maybe right on that. This explain why boost gauge is vibration at idle with no load. It look it was so quick vibration and I check scanner 2 weeks ago On MAP the pressure were bounce so quick it only record 2 sec data. It was vary from -1.2 to .49 at idle that why boost gauge were vibration.

 

Went outside and inspect again since I was worry about issue.

Exhaust pipe is dry expect alot soot lay on pipe. Look like it running rich?

Inspect valve cover gasket they look little wet but plan tight that tomorrow.

Going monitor oil level and write down on paper so I can remember how much oil it use everyday.


On Turbo Ebvp to exhaust pipe. On bottom of ebvp rod they look awful WET.

Turbo main housing missed 1 star bolt and it leak soot. This why I bought used turbo cause I suspect mine not rebuild-able due maintenance by previous owner.

 

Also make sure your hose by the transfer case isn't blocked or froze up before starting with the new turbo.

Good Idea I plan expanding that further by gas tank to get odor away.

 

How much you want for the turbo, if your not rebuilding it? Shipped to 92530.
