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??

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

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 agree that this would be the most likely scenario. But it's not very common for all 4 to be hydrolocked.The fluid would only come in through the open exhaust valves.

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???

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
