Now that you have broken the engine loose, one of the first things to do is change the oil. This will get rid of most of the dirt, acids, and excess diesel fuel. Pull the plug, remove the filter and let it drain for a day or two. Then, add a gallon or so of diesel fuel and a new filter, and turn it over with the starter for a minute or so. You'll be turning it over without spark plugs, so watch for spray coming out of the plug holes. It will turn much faster and build up some oil pressure while cleaning out the oil galleys and internals. You can cycle through a few times if you want. | Now that you have broken the engine loose, one of the first things to do is change the oil.

| − | You now have to make a choice: run the engine as is, or pull the heads and pan to check for damages. If you're going to do a compression test or a leakdown test, drain and re-fill with new oil and start the engine to warm it up and burn off some of the diesel fuel in the engine. In most cases you should go the overhaul route, checking for wear, mic'ing out the bores and clearances of bearings, etc. | + | You now have to make a choice: run the engine as is, or pull the heads and pan to check for damages. If you're going to do a compression test or a leakdown test, drain and re-fill with new oil. Circulate the new oil throughout the oil galleries by cranking the engine 50 crankshaft revolutions to purge the diesel fuel, and then start the engine to warm it up and burn off some of the diesel fuel in the engine.
