International DT466 – ENGINE SYMPTOMS DIAGNOSTICS – Oil and Crankcase Inspection

1. Drain oil from engine. Inspect oil drain plug magnet, drained oil and oil filter for foreign debris.
• An oil sample should be taken to determine level of engine wear metals and contaminants in the oil.

2. Remove oil pan following the procedure in the Engine Service Manual.
3. Inspect for missing, loose, plugged or damaged oil pickup tube, pickup tube gasket, piston cooling tubes, bearing        inserts, and cam bushings.
• If unable to identify any damaged parts, Go to “Pressurized Oil System Leak Inspection” in this section.

NOTE: The piston cooling tube was redesigned. The new piston cooling tube is lighter and structurally
stronger. The piston cooling tubes with knurling are used on the HT 570 and DT 570 engine. The piston
cooling tubes without knurling are used on the DT 466 engine.
