First time posting on the site, great amount of knowledge and resources so any help would be great. Truck is a 2006 F-350 6.0, ARP studs, Ford Head Gaskets, Bullet Proof Diesel Oil Cooler Kit and EGR with an SCT tuner on tow mode.
Towing approx 15,000 pounds noticed truck started to lose power and misfire. Pulled over and noticed engine oil all over the driver side on engine, looks like it sprayed to top of engine as well. Oil on valve cover, FICM, exhaust manifold. I looked under the truck and saw that oil is all over bottom of the truck, differential covered in oil as well. Looks like blue smoke coming from tailpipe and smells of oil burning. Cannot tell where oil originated from.
I removed the EGR Valve, to see if there was moisture on the valve and when I looked into the intake manifold there is engine oil pooled in the bottom of the intake manifold and on the EGR Valve. This is not dirty water from soot, it is oil. Truck is misfiring, with no codes being thrown. I noticed a small amount of white residue around the radiator cap however I had just filled up the reservoir, week prior. I unfortunately do not have gauges in the truck and rely on the factory gauges; coolant temps did not rise or move at all when this happened. I am not sure if I blew a head gasket, and really confused on how engine oil got into the intake manifold. I ran the engine with the air filter removed and can see blue smoke coming out of the CCV and oil in residue in front of the turbo inlet. Any help would be greatly appreciated.

 

Probably the turbo seal. Look inside the intake tubing for pooled oil. Spray some degreasser on the top of motor, spray that off and watch the turbo.

You could also have a leaking oil cooler cover.

Either way, you need cleaned up to see.

 

Thanks for the information, I will look tonight to see if there is oil pooled inside.

 

I had my top gasket go out on the oil cooler and it would puddle underneath the truck. I was towing the camper at the time and it got an oil bath on the way home. I've got my EGR plugged off, so I don't know if there was oil in the intake or not.

 

Pull the oil cap while it's running check for excessive blow-by (crankcase pressure). Check oil level and assess how much oil is missing to get an idea of how bad it is. Clean up under the hood and watch for leaks. Oil will run down so start looking on the top of the engine. Just a warning, if there a lot of oil in the intake system the truck could run off that and cause a run away. It won't shut down if you turn the key off.

 

Thanks for all the information. Would the oil in the intake cause the misfire? I am truly thankful for the help

 

Use the starter jumper wire or pull the FICM fuse/relay and listen for even cranking. For a better description, watch dieseltechron's YouTube video on checking for base engine issues. I'd post a link but I'm on my phone.

 

 

Thanks for all the help once again. Pulled the inter-cooler pipes and oil was pooled in the pipes. Had a lot of oil in the inter-cooler itself, probably 1/2 quart of oil. I pulled the turbo and noticed two of the bolts holding the front face plate had fallen out. I am assuming this has let oil come out of the seal. I pulled the intake manifold out to clean the oil of it and in process of putting everything back together. I am thinking of ordering a Powermax turbo instead of a factory reman, is this a good replacement turbo? I can have the tune updated for the new turbo once I order it. Or should I order a different turbo? Also should I re-route the CCV as well, is there a reason why this should be done to prevent future problems?

 

Powermax is a good sounding, power making, faster spooling upgrade. Re-routeing the CCV will keep crank case oil from making it into your intercooler, some argue it shortens the life of your boots but theyre designed with oil in mind to begin with

 

Well after putting new turbo on and cleaning out the intake and inter-cooler, truck still did not run. Ended up pulling the heads off to replace head gaskets in case they were bad. Took the head of passenger side and noticed a burn mark in the cylinder wall. Looked further and found a hole and cracked piston in that same cylinder. Have no idea what would have caused this other than oil getting into the cylinder and trying to compress the liquid. In process of removing the motor to get worked on.

 

Ouch......
