Cleaning the oil pump pickup screen typically involves using a specific fluid to help break down and remove buildup.
According to one method, cleaning the oil pump pickup screen involves introducing a predetermined amount of a specific flush fluid directly into the oil pan. This fluid is then allowed to remain in contact with the oil-pump pickup screen for a sufficient time. The purpose of this contact time is to allow the flush liquid to thoroughly mix with any disintegrated and dislodged buildup that has formed on the screen. This buildup can include hardened carbonic and other combustion residues.
The Process Explained
Cleaning the pickup screen isn't usually a standard maintenance task like changing your oil filter. It's often done when addressing specific issues related to oil flow or engine sludge. The method described involves:
- Adding Flush Fluid: Introduce a specific, predetermined amount of a cleaning or flush fluid into the engine's oil pan. This fluid is designed to dissolve or loosen deposits.
- Soaking: Allow the fluid to soak the oil pump pickup screen. The time required is 'sufficient' to ensure the fluid can interact with the accumulated grime.
- Mixing with Buildup: As the fluid soaks, it mixes with and helps break down hardened deposits like carbonic and other combustion by-products that may be clogging the screen.
This process helps free the screen from blockages, improving oil flow to the engine. It's important to note that this is typically part of a more comprehensive cleaning procedure, and the dirty flush fluid would subsequently need to be drained and replaced with fresh engine oil.
Why Clean the Pickup Screen?
The oil pump pickup screen acts as a first line of defense, preventing large particles and sludge from entering the oil pump and circulating through the engine. A clogged screen restricts oil flow, which can lead to:
- Low oil pressure
- Insufficient lubrication
- Potential engine damage
Ensuring the screen is clean is crucial for maintaining proper engine health and longevity.
