Change your oil/filter and switch to 100% synthetic. Drive it 1,000 miles and change the oil/filter again. This time add a can of Seafoam Engine Treatment to the crankcase that you can buy at most auto parts stores. Drive it another 2,000 miles and change the oil again and add another can of Seafoam. Drive it 5,000 miles and change the oil/filter. This should remove lots of the sludge.
Remove the oil pan from the engine and clean it with kerosene.
Only if you use poor oil and don't keep it clean.
Sludge in an engine is cause by poor maintenance. Air and contaminants build up over time to create a thick sludge throughout the engine.
A motor flush is designed to help clean any sludge from the engine. A cleaner system will make fluids flow easier, and make the engine last longer.
What I like to do from time to time is add a quart of Transmission fluid about 3 days before an oil change, the transmission fluid has detergents that clean out any sludge from your engine. of coarse if you never change your oil and its thick as tar you may need professional help for your car.
To clean a crankcase breather on a small engine, first, ensure the engine is cool and disconnect the spark plug for safety. Remove the breather from the engine, then clean it using a solvent or carburetor cleaner to remove any oil sludge or debris. Rinse it with clean water, allow it to dry completely, and reassemble it back into the engine. Finally, reconnect the spark plug and start the engine to ensure proper operation.
sludge
A buildup of sludge inside an engine can be caused by several factors, including inadequate oil changes, which allow contaminants and debris to accumulate. Poor-quality oil or incorrect viscosity can also contribute to sludge formation by failing to properly lubricate and clean the engine. Additionally, operating the engine at low temperatures or short trips that don't allow it to reach optimal operating temperature can lead to condensation and moisture buildup, further promoting sludge development. Over time, these factors can significantly hinder engine performance and longevity.
Engine sludge is what the dealer told me Engine sludge is what the dealer told me
Engine sludge formation includes, lack of proper maintenance, inappropriate oil temperature, use of an inferior engine oil, and engine oil contamination. You can try flushing it out with an oil flush additive but often times this does more harm than good.
You should not clean an internal combustion engine unless you are going to tear it down, using solvent to break up sludge will deposit it in the oil pan, clog the oil pump pick up and you will then loose oil pressure leading to engine failure. If you still want to do this you must remove oil pan and oil pump pick up and clean after de-sludge. Don't trust this repair to just anyone. Know your mechanic.
I went to Lincoln Tech Auto school and the Professor in my Automatic Transmissions class told me the best thing to do, to clean out your engine is to put Automatic Transmission fluid in it and run it over the weekend and then change it out with regular motor oil.
