==Inspection==
===Oil Pan===
Interior with oil screen removed and tilted up to see area clogged with oil deposits. Bottom of oil pan is covered with a tar-like layer of oil deposits.

===Oil Screen===
The screen was about 80% plugged. Probably just enough free area left to maintain minimal oil pressure.

===Metal in Oil Pan===
Close-up. Small flakes of metal were found embedded in the layer of oil deposits in the bottom, between 1 and 2 mm in size (some spots are reflections). No metal was found in drained oil earlier, and almost nothing was found on the magnetic oil drain plug.

===Bearing Damage===
One main bearing and one rod bearing were removed for inspection. The rod bearing showed heavy wear. Using the Haynes manual as a reference, it resembled example F in diagram 15.2, chapter 2B, "craters or pockets".

===Cracked Rod Bearing===
When both main and rod bearings were later replaced, one of the rod bearings came out with layers of metal stripped away, and one of the half-shells in pieces. The picture shows the reason for the amount of metal found in the oil pan.
