Datsun 1200 uses a tradition wet-sump oil pan, holding about 2.5 quarts of oil. It is a sheet metal part that plays no structural function. It is a front-sump design.


Oil Capacity

Datsun 1200 1971-1973
* Oil pan: 2-7/8 U.S. qts., 2-3/8 Imper. qts. (2.7 L)
* Oil filter: 1-1/8 U.S. pints, 1 Imper. pint. (0.54 L)
* A12/A14/A15 oil pan: 2.8 liter
* A14 mid-sump oil pan: 3.2 liter?

The exact amount depends on the specfic oil filter used. Nissan oil filters come in several different sizes.


* Early A-engine 1966-1973 (A10 & A12) oil pans interchange
* Late A-engine (A12/A12A/A13/A14) use the same oil pan
* B210 North America uses a unique mid-sump pan
* A15 uses a unique oil pan with bulges on the side

Late pans may be used on early engines, but not vice-versa due to a slight change in the pan rail shape.

The Datsun Factory Service Manual says to use sealer on both sides of the oil pan gasket, "especially on the front and rear portions of the pan". I believe the original was a cork gasket.

Oil pan side rails, cork or otherwise, needs no extra sealer. What it needs is:

  1. ensure the pan flange is flat. Many have been overtightened and won't seal correctly until straightened
  2. a dab of RTV sealer on the ends where the half-round gaskets meet the rail-sides. Do not put very much on.
  3. Do not overtighten. Factory torque is really low (they are only 6mm bolts). Tighten them to spec, then go round again and retighten.
Torque spec
0.4 to 0.6 kg-m
2.9 to 4.3 ft-lb
35 to 52 inch-lb

Early Blocks

1967-1973 - front distributor engine blocks
* Front Sump (B10 and B110 may interchange)
* B10 pan is shallower
* B110 pan is deeper

A12 VS A10
174_57a000cf5cbb0.jpgPost 480296 174_57a000efe74f3.jpgPost 480296

Newer pans from Datsun 120Y and B310 will fit the older A12. When the distributor was moved back for 1974 there was a change in the pan rail shape under the oil pump area which may prevent interchangeability between older oil pans and newer engines.

B110 pan has stiffening ribs (shown). B10 pan is smooth

1974 up Blocks

1974-up (mid-distributor) engine blocks. All the A-series pans bolt to all A-series engines, but be sure to get the matching dipstick, dipstick tube and oil pump strainer to go with the pan.

Front sump A12, A12A, A14
* 11110-H5000 OIL PAN [same as JDM B210] 
Mid-sump (North American B210)
* 11110-H7201 ASSY-PAN OIL
** Replaces 11110-H7201, 11110-H6200
A15 front sump pan with bulges, will retro fit into other A-series mid-dizzy engines.
* 11110-H9700 OIL PAN [unique to A15] 

Beware of using an early A-series pan on late engine.

Late pan -> all engine
Early pan -> early engines only

HB210 Pan

North American B210 engines (A13 & A14) used a mid-sump (center sump) design. The oil pickup tube has a unique part number.

A15 Pan

11110-H9700 A15 pan with side bulges + stiffening ridges on bottom surface (for quieter operation)
25715.jpgAlbum 25715

The lack of clearances bulges on the B10/B110/B210 type pans prevents use on the A15, however the presence of bulges on the A15 pan does not interfere with its use on other rear distributor engines (engines made after 1973).
