4. Wait, while oil will flow down. Do not forget that, probably, you should move capacity when a stream oil will decrease, and it will begin to flow down separate drops.
5. After all oil was merged, wipe a cap of a drain opening and a sealing washer a pure rag. Examine a sealing washer and replace it if it is scratched or damaged. Clear area round an opening for plum of oil and twirl a cap into place, having established a sealing washer. Reliably tighten a cap.
