04 6.0 hydrolocked

[craig4108]

Ok guys my 04 is hydrolocked all 4 of the cylinders on the passenger side have oil in them. Could the oil cooler have failed causing this, or possibly the turbo??? Also how can I get the oil out of the cylinders after I find what is causing the problem??

I am going to say pull the GP's out, and then you can get at each cyl to the the oil out. Not sure what would cause that to lock on ya... good luck. Here is a free

Another classic EGR cooler failure causing coolant to fill bank #1 by the sounds on things.

would an egr cooler failure cause oil to fill all the cylinders on passenger side? Could it be injectors??

What makes you think it's oil? For what it's worth, coolant breaching the exhaust system mixing with the soot will appear similar to oil.

I did not loose any coolant that I could tell. The coolant level is at its normal mark. The last time I drove it before it hydrolocked it was idling bad and knocking. It also was low on power. Just doing 65-70 I was pulling about 25 psi on the boost gauge. What is the best way determine if it is oil or coolant???

Find out what happened?

So it was knocking and idling bad and you drove it?? Could also be fuel. Did you pull the glow plugs and turn it over yet?

how do you know oil is in the cylinders? pull glow plugs and try to start it, ive hydro locked mine a few time...if u drive it to much with it knocking and running horrible u better hope you didnt bend a rod, and if u try to start it and it thunks and stays locked dont not keep trying or you will bend a rod and burn a starter up real quick so dont hold that key over hoping it to tun over

more than likely its injector failure but i doubt all 4 went out at the exact same time
