Engine sludge buildup is a recurring issue in some vehicles.
Dynamic engine service can help address this problem.
This service was performed on a Honda Odyssey. It was running rough and the check engine light had turned on.
We started the process by adding engine cleaner. Once the engine reached its operating temperature, we drained the oil and changed the oil filter.
Draining engine oil
Engine cleaner was added again and the engine ran in neutral for 45 minutes.
Then, our technician drained the engine cleaner and replaced the oil filter before adding new engine cleaner and running the engine in neutral for 20 minutes.
Afterward, the oil filter was changed, and new oil and oil conditioner was installed.
Throughout the dynamic engine service, we watched the engine oil pressure. If the pressure drops, it could mean that something is blocking the oil pump suction line strainer.
Monitoring engine oil pressure
This procedure is recommended for cars that experience sludge buildup as a repeat problem.
Sludge — old, thick oil that is sticking to the engine — can get sucked into solenoids and other components, causing them to go bad.
Some vehicles are prone to sludge buildup. It also depends on the driving style.
Having proper oil maintenance performed with high quality oil is another way to prevent sludge from building up.
With today’s engine and the variable adjustable camshafts, making sure the oil ports are clear are very important. It can cause rough running conditions, as was the case with this Honda.
