coolant in the oil culprit found

Well, the verdict is in. A couple days ago my radiator emptied into the block in a matter of minutes. Didnt run long enough to overhead or even show a change in oil pressure. However, it did make an enourmos amount of chocolate milk. While looking for the leak and preparing to remove the heads I founf the oil pan gasket leaking pertty bad so i decided to just pull the block and take care of it all in one shot. I found the leak. A freeze plug in the top front of the right side head was blown out. I havnt removed the head yet but expect to see a blown gasket there. ( I hope anyway ). My question is, aside from totally breaking down the block and having it vatted, how can i clean all that chocolate milk out of there. Its everywhere. Its even oozing out of the turbo, it in the intercooler. Everywhere. Also, Could a blown head gasket between the cylinder and a coolant passage cause enough compression in the entire cooling system to actually blow out a freeze plug. I would have thought something much weaker would have let go. I plan to regasket much of the engine, paint it, new compressor wheel, larger down pipe and larger up pipes, and im seriously considering a new HPOP. Anything else you guys recommend without having to spend 5 or 6K.

Yep, compression may blow out a freeze plug. As far as cleaning, I'd clean and check everything.

Are you going to tear it down? A powerwasher with detergent will clean most anything.

if compression blew that plug out, its unlikely its the gasket...the more likely source is cavitation through one of the cylender walls blowing the compression through a hairline crack.....but its tough to say initially. You should have the whole block magnafluxed if the gasket doesnt show any signs of failure..... just another thing to think about....

simple green works very well for cleaning oil. I would pull all the freeze plugs and flush it well.....then when you first run it, put about half a gallon of simple green in it and run that for the first 100 miles.....then drain the simple green, run strait water for another 100 miles...the put mixed coolant in it...that sould get most of the oil out of the cooling system.... as far as the block itself....dont worry about the small amount of suff that will be left...the amount you get out draining the oil is fine....the rest will get burnt out just like normal condensation does....u might do your first oil change at 1k just to be safe...
