Ok so I bought this truck and noticed I have an oil leak. I don't know where it's coming from quite yet. Looking into it in the morning. There is a huge puddle on the drivers side I look up from the bottom and it is coming from the front and back of the engine. Don't really know if it's coming from the top and just pouring into the valley or what. Also the check engine light is not on but my buddy hooked his obd II up and got 9 codes! P0728 #6 injector bad. P0678 #8 glow plug, P0677 #7 glow plug, P0673 #3 glow plug, P0672 #2 glow plug, P0671 #1 glow plug, P0401 egr flow insufficient, P006A MAF correlation, and U030 software of FICM not compatible. I need help on this. Also truck starts to shake going like 45-60 down the highway. Any help is appreciated.

 

That's a whole lot of codes , How many Qts are you adding , 13 1/2 seems like it stops the bell housing drip, may have to look closely at the Glo plug harness most will break when trying to remove them, have you removed and cleaned up the EGR Valve they do get all sooted up, your Injector needs a Contribution test done to see what it's doing, I have to look again I forgot to quote your post.

 

U0306 , have you done anything recently like new FICM ?, PCM? , first I would check the three FICM Connections , make sure they fully seated , If so then monitor V-ref let's see the Vehicle Volt out put. should be 4.95 5.00

 

Could the shaking be a tire issue?

 

good idea, try putting it in a gear and keeping it at the same RPMs when you get the shaking and see if it happens at different speeds but the same RPM.
also just an idea here but could multiple glow plug codes be caused by a bad GPM?

i had the same MAF code and cleaning it fixed that.

 

X2 I was thinking the same thing... If #6 injector is truly bad, replace it with a Ford reman!

 

Ok i will try the replacement when I get the money and it seems when I go in overdrive with the transmission like the last gear is when it starts shaking but when I go above 65 the shaking stops. I still haven't looked at the oil leak issue but it seems like it's coming up top ish. I went under it and seen the leak all over the tie rods. Also it is running down the oil pan and dripping off the bolt. Also I think the previous owner put the newer ficm in it and a newer turbo.

 

Check the CAC tube boots, especially the cab side of the boot at the turbo outlet. They develop small cracks that only open up under boost. Since crankcase gases are vented back into the intake, and they carry a little bit of oil, it adds up over time and gets into the turbo and CAC tubes, and comes out those cracks.

 

Turbo Oil feed line? and where the turbo sits on the petastool the o-ring there. also ICP and IPR are under the Turbo on the early built trucks stick a mirror up in there and have a look.
