Collecting fluid in the cam galley
Start the flushing process from the top of the block through the top cam oil feed holes. A squeeze bottle or similar container can be used to flush. Collect the fluid in a container that can easily fit into the camshaft bore. Collection of all top holes should be sampled through the contamination kit (P) and the 561-2030 47 mm Filter Element (Q). Refer to Illustration 20.

Turbocharger supply passage
First flush the two side oil passages at the front of the block, refer to Illustration 27. Second flush the two turbocharger supply passages refer to Illustration 29.The fluid will drain to the main galley and accumulate in the bottles (M) and the Oil Canister (L).

Example of finished fabricated tool.
Clean steel tube prior to inserting block and flushing main oil galley.
Remove the oil canister from the oil inlet hole. Remove the sample bottles from the mains and spray jets holes. Pour the collected liquid through the contamination filter element kit tester.
Analyze the 561-2030 47 mm Filter Element according to the following information. If any value exceeds any limit, rewash the block and perform the inspection again.
Rinse out the all sampling bottles, fittings, and containers. Remove the Cover Plate (H) from the rear of the engine and catch any fluid present. Run all fluid through the test filter element to catch any remaining debris.
Flush oil supply lines that have been previously removed from the engine to catch any remaining debris. Pour the collected liquid through the contamination filter element kit tester. Refer to Illustration 16 or 17 for component identification.
Flush the clean side of oil filter base that has been previously removed from the engine to catch any remaining debris. Pour the collected liquid through the contamination filter element kit tester. Refer to Illustration 16 or 17 for component identification.
Analyze 561-2030 47 mm Filter Element for the oil supply lines and oil filter base according to the following information. If any value exceeds any limit, rewash the oil supply lines and oil filter base and perform the inspection again.Particles
Particles to be measured for size are metallic, rust, sand, and other abrasives.Note: Abrasive materials are defines as particles exhibiting a crystalline structure and a Mohs Hardness of 6 or higher.Typical examples of abrasives are listed below:
aluminum oxides
aluminum zirconium
silicon carbides
silicon oxide (sand)
cubic boron nitride
carbon carbide
tungsten carbideNote: Glass in the form of beads or other non-crystalline shapes are also considered abrasive particles.Filter Element Review
