to the ones who know
after many attempts to start my 2002 volvo diesel 1989 and some back flow problem after overheating the oil cranks fill up wit salt water back flowing from exhaust elbow and now I have a grey sludge and can not crank the engine
one of the problems is the emulsification is so intense than haven't being able to siphon the sludge
sugestion,procedures ,
good decent diesel mechanic to recommend on the fort lauderdale area?
thanks in advanced

I'd try "thinning"the oil maybe with mineral spirits of similar so that I could syphon it out, assuming you cannot drain it out through the oil pan drain plug. Can you put a bigger rubber hose on the outside of the dip stick tube as opposed to a thin plastic hose inside of it?
Of course you know you must get it out, put cheap oil in as you'll only run it for a few minutes before you drain that out, you must continue the is drain and flush until all water is removed.
I'm sure you know what caused the water in the oil and won't repeat that mistake.

I'd even try using a shop vacuum as a blower to try to pressurize the crankcase enough to help blow the oil out of the dip stick tube.

Oh, and it the engine is locked up, it may be that a cylinder is filled with water and since you can't compress water, it's locked up. If you have de-compression levers, pull them and that should let the water out of the cylinder, or pull the injectors to let the water out.
Close the sea-cock while your doing this of course, and I'd try turning the motor by hand to bleed the water out, not by the starter

If the engine is locked you will never fee it up. it will need pulled. I can pull it and rebuild it im a lot cheaper then most but im not working for shortcuts either I live two hrs away. pour transmission fluid in there its your only hope.

You need to get this out as soon as possible. Fresh water's not that bad but salt water will cause rust quickly. You can't turn it over because there is water in one or more cylinders which cannot be compressed. As previously posted use the compression release lever at the top of the block. You can pour kerosene or diesel fuel into the motor to clean it & thin the water/oil mixture. Do this a couple of times to flush it. Then put in oil & run it but only run it for a short time & change the oil. Then run it for a short time & change the oil again. At this point the oil should be crystal clear. Now you need to run it under load for an extended period. If you can tie it up at the dock & keep it in gear do that. Listen for bad sounds & check for oil leaks. Also check for smoke. I'd run it at the dock for at least an hour. If it's ok you're probably good to go but keep a good eye on it on your next trip.

What kind of engine don't it have inspection covers on the side? Use the trans fluid like I said the oil fill tub will never get it all out.keep filling and draining if you have no other way.

It would be premature to pull this before you know if there's a problem. Flush it, clean it, run it. If there's a problem you still need to figure out what it is before you pull it. FYI, a rebuild on a 2003 is very expensive. A friend of mine had his 2003T rebuilt a couple of years ago. It cost $11,000. It does not make sense to rebuild this motor.
