OEM Oil Squirters: 1g DSM

Genuine OEM parts.

We carry 3 different OEM oil squirters for 1g DSMs: 6-bolt DSM style (MD329806), 1g 7-bolt DSM style (MD329807) and EVO style (MN143460).

The EVO squirters are slightly shorter and angled slightly differently than the DSM ones. As a result, there's extra piston clearance for certain applications. For example, many aftermarket pistons (especially forged) have piston skirt designs that would interfere with the stock DSM squirters. It should be noted that the EVO-style squirters can be used in either a 1g 6-bolt or 1g 7-bolt block.

An oil squirter (sometimes called an oil jet) is comprised of two main components:
1) squirter body--directs oil toward the underside of the piston.
2) banjo check valve--a specialized banjo bolt (which contains a check valve) that delivers oil to the squirter body when a specific oil pressure is reached.
The entire assembly is sealed with a pair of crush washers (MF660034x2). The same crush washers are used for all styles of squirter.

Each squirter is held in place by the banjo check valve which threads into the block (MD050249 for DSM-style squirter body or MD372046 for EVO-style squirter body). The squirter body also contains a pin which locates it in a precise orientation in the block. These crush washers are included with the banjo bolt/check valve, whether new squirters are ordered or not.

NOTE: Even though any of the 3 squirter styles can be used in a 1g block, all the components are NOT interchangeable. For example, DSM squirter bodies should be matched to DSM banjo check valves and EVO squirter bodies should be matched to EVO banjo check valves. DSM and EVO components should NOT be interchanged. This is due to the slight differences in squirter body thickness between the two styles.

NOTE: 6-bolt DSM and 7-bolt DSM banjo check valves are the same part (MD050249).
