Note: This is a rear main bearing cap from a 1600 engine. It does not have the screwed in down tube that was used on the 1500 engine, but instead uses the two large drilled drain holes seen here in the last view above. The two small drain holes we drill are still located the same.
Rear cap installed (without crankshaft).
Note: When installing the cork seal, paper gasket and rear plate,
it is important not to obstruct the newly drilled drain holes.
Rear cap installed. Inside view with block inverted.
New drain holes through bearing cap, with punch through hole.
