==After the engine has broken loose== 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 penetrating fluid. Pull the drain plug, remove the filter and let it drain. Refill with clean motor oil and install a new filter. ===Engine flushing=== {{Note1}} There is quite a bit of controversy regarding using various methods to flush/clean an engine that's been neglected. One school of thought is that it's better to leave it be, if the engine cannot be taken apart for a thorough cleaning. An engine that's had regular routine oil and filter changes will be relatively clean inside. Using a flush to clean it out won't accomplish much except to loosen what there is in there already. Once the crud is softened up, it can take a long time to ever be removed totally. It can take several oil changes to bring the engine back to a state where the oil and filter isn't immediately contaminated with the loosened dirt. Beyond that, there may be no damage done. The decision to flush the engine will be left up to the person paying the bills. It is strongly recommended to research this fully before undertaking the procedure. The following is one of many methods for flushing an engine: *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. *Use a commercial engine flush, following the directions. *Fill (fully or half and half, etc.) with ATF and run the engine.
