Additionally, if you are swapping a 3.4L into any 1986-1995 4WD IFS application (4-cylinder or V6), you will need the oil pan part number 12101-65012 (88-95 V6 4WD pan). If you are performing the same swap but for a 2WD 4Runner, the part number remains the same. However, for a 2WD Pickup, you will need the part number 12101-65021 (88-95 2WD V6 pickup pan).

It is important to note that the oil pan part numbers provided are specific to the Toyota models mentioned. The part numbers for the oil pan gaskets, pickup tubes, and other components may vary depending on the specific application and vehicle configuration.

When performing an oil pan conversion or engine swap, it is always recommended to refer to the vehicle's service manual or seek advice from a qualified mechanic to ensure the correct parts are used and the procedure is carried out safely.

Oil pickup tubes

When performing a 3.4L V6 Toyota engine swap, the oil pan and oil pickup tube required will depend on the specific vehicle configuration. For example, if you are swapping a 3.4L engine into a 2WD Toyota Pickup from 1984 to 1995, you will need oil pan part number 12101-65021 and oil pickup tube part number 15104-62060.

If you are performing a Solid Axle Swap (SAS) on a Toyota Tacoma from 1995 to 2004 or a Toyota 4Runner from 1996 to 2002, both with a 3.4L engine, you will need a rear sump oil pan with part number 12101-65030 and oil pickup tube part number 15104-62060. This rear sump oil pan is also suitable for Solid Axle (SA) vehicles.

It is important to use the correct oil pickup tube that matches the oil pan and engine configuration to ensure adequate oil supply to the engine.

In addition to the oil pan and oil pickup tube, other components such as gaskets, dipsticks, and adapters may be required for a successful engine swap. It is recommended to refer to vehicle-specific forums and resources for detailed information on the required parts and installation procedures.

Dipstick and dipstick tube

When performing a SAS 3.4 swap, one of the critical components to consider is the oil pan, which plays a vital role in lubricating the engine. The oil pan needs to be compatible with the specific engine and vehicle configuration to ensure adequate oil capacity and clearance. In this regard, the dipstick and dipstick tube are essential elements that warrant careful attention to ensure a successful SAS 3.4 swap.

The dipstick serves the fundamental purpose of checking the engine oil level. It is a thin, long metal rod that is inserted into the dipstick tube, which runs down to the oil pan. By pulling out the dipstick and inspecting the oil level on it, you can ensure that your engine has the appropriate amount of oil. A critical aspect of the dipstick is its length, which needs to be accurate for your specific oil pan and engine configuration. An incorrectly sized dipstick can lead to inaccurate oil level readings, potentially resulting in engine damage.

Now, turning our attention to the dipstick tube, its function is to guide the dipstick into the oil pan and provide a path for oil to flow back down if excess oil is added. The tube is usually made of metal and is firmly attached to the oil pan, ensuring a secure connection. A critical consideration when choosing a dipstick tube is the angle at which it exits the oil pan. This angle must align with the location of the dipstick provision on your engine block. A mismatch in angles can result in a cumbersome dipstick assembly and potential leaks.

Additionally, the length of the dipstick tube is of utmost importance. It needs to be the correct length so that the dipstick can reach the oil pan and provide an accurate reading. A tube that is too long or too short can lead to difficulties in inserting the dipstick and may result in incorrect oil level indications. Thus, it is imperative to verify the precise measurements of your engine and oil pan setup to ensure the dipstick tube you choose is compatible.

Solid axle swap (SAS) on a 95-04 Tacoma

A solid axle swap (SAS) can be performed on a 95-04 Toyota Tacoma, which involves replacing the front independent suspension with a solid axle. This modification is often done to improve off-road performance and durability.

Kits and Parts

There are several companies that offer SAS kits specifically designed for the 95-04 Tacoma, such as WFO Concepts, Yotamasters, and Trail-Gear. These kits typically include components like radius arms, coil-over shocks, axle brackets, and steering components.

One key consideration for a SAS on a Tacoma is the oil pan. The stock oil pan on a Tacoma with the 3.4L engine has a sump in the front, which can interfere with the solid axle and steering components. Therefore, it is necessary to replace the oil pan with one that has a rear sump, such as the oil pan from a 2WD T100. This conversion ensures that the oil pan does not interfere with the axle and provides adequate ground clearance.

Procedure

The procedure for a SAS on a 95-04 Tacoma typically involves removing the factory suspension components and installing the new solid axle, radius arms, and steering components. It is a complex process that requires mechanical skills and welding. The axle is typically sourced from a Ford Super Duty truck, which requires some modifications to fit the Tacoma.

The oil pan conversion is an important step in the process. The stock oil pan is removed, and the new rear sump oil pan from a 2WD T100 is installed, along with a new oil pan gasket, sump gasket, dipstick, and other necessary components.

Benefits and Considerations

The benefits of a SAS on a Tacoma include improved off-road capability, durability, and ground clearance. It allows for larger tires and lift kits to be installed, enhancing the vehicle's performance in rugged terrain.

However, there are also considerations to keep in mind. A SAS can affect the vehicle's handling dynamics on paved roads and it may require modifications to the brake lines, driveshaft, and other components. Additionally, the radiator may need to be replaced, especially if the vehicle has a 3.4L engine.

In conclusion, a solid axle swap on a 95-04 Tacoma is a complex modification that requires careful planning and mechanical expertise. It offers improved off-road performance and durability but may also require additional modifications to ensure compatibility and optimal performance.
