      I don't think the flush is designed to be left in verry long (I've only used the caustic type of flush)... there was a write up on "oilburners.net" in the 7.3L idi diesel forum that talked about running some kind of household detergent through your cooling system to clean out all of the oil residue... don't do anything until you can read up on it and know for sure...
      Sometimes it just takes a bit longer to get all of the residue out.
      I hope this was some help.

      hmm ok i will do some research and see what type of detergent and go from there.

      Anyone know if the thermostat housing have oil lines that run thru it? What other parts of the motor have both oil and water lines running thru it?

      Does anyone knows if the oil restrictor is damaged will it cause oil to back up and then leak into the coolant?

      first off. please learn some punctuation. second, if oil and coolant are mixing, then you have a headgasket failure.

      First off this is not school nor is it a paper. Second you can keep your comments to yourself I can type how I want to this is just a question I am not being graded on. Head gasket all ready been changed car is not running hot, nor sluggish or anything for it to be a sign of head gasket this is only issue it is having thank you. I will be looking into it more.

      How much oil are we talking about? If it's just trace amounts, could be residual.

      Water and oil aren't supposed to mix. Like someone else said, it's probably a head gasket failure.

      I would change your oil and see if any coolant got into your crankcase.

      Question oil/coolant mix

      It is possible the head gasket can be faulty?
      Its lot of oil in the bottle within a week like 2 quarts is gone out of it after water bottle is drained once or twice before it will show back to normal on the dip stick. I am telling the guy he will have to go back, take it down and check the head gasket again. He asking what does he have to look for? Could the gasket been put on backwards, or bolts not torqued correctly? What else would be good to look for exactly?

      Also someone said something about an oil restrictor located on the head if its cracked/damaged which it was not changed at all would it back up the oil to where it will cause oil to go under gasket instead?

      Guy is trying to convince me to spend 900 on another motor. If there is not anything major but head gasket gone out again or something small that would save me a lot of money. I want to make sure everything has been tried before I go spending all this money that can be avoided. Thanks to everyone taking the time out to comment and help me out. I really appreciate it very much.

      That's a lot of oil... I would suspect the head gasket... I'm no expert on these engines but I wouldn't know how oil would "back up" from a oil passage in to the coolant... sounds like someone did a job wrong and now is trying to avoid redoing it right.
      Case in point... my wife brought her car to the dealer to have the computer reflashed right after I changed out her water pump... because there was antifreeze on the engine they told her it "was POURING coolant out and she needed a new water pump... I show up and their tune changed in a hurry.
      Good luck.
