The Oil Level Gauge, commonly called a Dipstick, differs between early and late A12 engines.

Overview

Early type goes directly into block (1967-1973)

Late type goes into a tube which is inserted into block (1973-up)

The H50 gauge is used by B210 and B310 A12/A14/A15/A12A

Oil Level

Oil should be between H and L marks.

Marks are the same for early (H10) vs late (H50) gauges, even though the overal gauge length differs. That's because they use the same oil pan! The oil level from the bottom of the pan is what is important.

Tube Removal

Use vice-grips and tap it up and out while twisting back and forth.
