Oil pressure relief plug extractor Porsche 911 / 964 / 993 / 996 / 997

Tolerance between the pressure relief plug and its galley are very close, and the slightest bit of gunk, corrosion, or bur will cause the plug to freeze up in the oil passage. A magnet is rarely powerful enough to overcome the seized plug, and leaving it in place is never an option.
Using STOMSKI RACING's Oil Pressure Relief Plug Extractor makes the task of removing the stuck plug a breeze, and allows you to ensure clean oil passages, and a properly operating bypass system.

The collet-based tool slides easily into the open end of the seized plug and a simple turn or two of the internal socket head cap screw expands the tool, grasping the plug to ensure easy removal.

Description of Tool
This is a 3D Printed tool for installing the Rear Main Seal on Porsche M96/M97 engines to the correct depth without damage to the seal. The tool is 3D printed from hard, black plastic and is very solid and durable. It is aimed at DIYers and hobbyists due to its low cost in comparison to the official Porsche tool, but would be well suited to small independent garages as the tool can be reused many times without damage.

How to use
Care must be taken when using this tool as although it is designed to make the installation of the seal as easy as possible, it is still possible to damage or incorrectly install the seal if care is not taken to install the seal properly. We accept no responsibility for incorrect usage of the tool and possible damage to the seal or engine of the vehicle. We advise you to always confirm with a digital calipers or other measuring device to make sure the seal is installed at the correct depth.
To use this tool you will also need 4 M10 X 75mm bolts and 4 washers. This is to allow for the extra thickness of the tool, and to spread the force from the bolts across the surface of the tool.
The seal must first be correctly orientated and then gently located into the opening around the crankshaft. To do this, leave the blue plastic ring in place and place the seal over the end of the crankshaft. Then push the seal on gently so that the end of the crankshaft pushes the blue ring out of the seal and the seal gets pushed onto the outside of the crankshaft.
Next place the RMS fitting tool over the seal and thread each of the 4 bolts into the crankshaft, through the holes in the tool. Make sure to orientate the tool so that the cut-out for the flywheel guide pin in the crankshaft lines up with the pin. Screw each bolt in slowly until they just about make contact with the face of the tool. From this point on the seal will start to be inserted into the engine.
Turn each bolt a quarter turn at a time, turning all 4 a quarter turn before tightening the first one again, and continuing the cycle. It is very important that the bolts are tightened small amounts, one at a time to make sure that the seal is inserted straight and not at an angle which will damage the seal.
Repeat this until the face of the crankshaft comes into contact with the inner face of the tool and it will not push the seal in any further. Remember that the tool is plastic so excessive force at the point will possibly damage the tool and push the seal in too far.
The 4 bolts can now be unscrewed and fully removed from the crankshaft. The tool can then be removed. It may be a slightly tight fit, and if it is difficult to remove by hand then there are slots in the sides of the tool to allow a screwdriver or prying tool to grip the tool and remove it. If using the slots, be careful to apply even force to both sides to ensure that the tool does not come out at an angle and get stuck or potentially move the seal.
Once the tool and bolts are removed, visually inspect the seal to make sure there is no damage. Then, use a ruler, digital callipers or depth gauge, check the depth of the seal. It should measure 13mm, from the face of the crankshaft to the face of the seal. As long as the tool was used correctly and is suitable for your engine, the seal will be installed at the right depth.
These instructions are only intended as a rough guide, you should always check a workshop manual or research online to ensure the part is being installed correctly. Using this tool requires some practical knowledge so if you are not confident in your abilities please do not attempt to install the seal yourself.

Because the M96 engine uses a multi-chain system with variable chain tension, maintaining the correct load on the chain is critical. Without controlled tension, the camshafts can drift out of position, resulting in misfires, camshaft correlation faults, loss of power or severe internal engine damage. This tensioner tool ensures safe and repeatable timing alignment during every rebuild or service.

What This Timing Chain Tensioner Tool Does

This specialised tool allows technicians to:

• Apply accurate tension to the timing chain during timing setup
  
• Prevent camshaft rotation while timing adjustments are made
  
• Support correct alignment of camshafts and crankshaft
• Replicate operational chain loading for accurate timing calibration
  
• Assist with IMS-related timing work
• Improve precision during rebuilds, head gasket repairs and chain tensioner replacement

It is essential for working on the complex timing system of the M96 engine - Ideal for any workshop servicing early and mid-generation water-cooled flat-six engines.

Why Timing Chain Systems Fail on Porsche M96 Engines

The M96 engine is known for specific timing chain vulnerabilities, including:

• Chain stretch due to age and heat cycles
  
• Worn chain guides, especially the plastic guide rails
  
• Hydraulic tensioner fatigue, causing intermittent timing rattle
  
• IMS bearing wear, which can influence chain tension
  
• Oil contamination, impacting tensioner pressure
  
• Incorrect tension set during previous repairs
• Thermal expansion, causing chain slack or misalignment

Symptoms commonly include timing rattle on cold start, poor idle quality, VVT faults, misfires and check-engine lights.

Why You Should Replace or Use a Precision Timing Chain Tensioner Tool

A timing chain tensioner tool designed for the M96 engine ensures:

• Accurate chain tension for safe timing setup
• Correct camshaft and crankshaft synchronisation
• Protection against piston-to-valve contact
• Cleaner, faster and more precise timing chain installation
• Fewer diagnostic errors during camshaft timing verification
• Reduced risk of long-term engine damage
• Professional-grade results, even in home workshop settings

This is a must-have tool for any timing chain or IMS-related service on the M96 engine.
