Will this Flywheel Seal Installation Tool fit my specific Bus or Vanagon model and year?

Yes! The GoWesty Flywheel Seal Installation Tool is designed to fit all 1968-1991 Volkswagen Bus and Vanagon models equipped with Type II and Vanagon engines. It's a perfect fit for both air-cooled and water-cooled engines, ensuring you get the correct, even pressure needed for flawless flywheel seal installation without risking leaks or seal damage.

Is this tool easy to use for DIYers, and how does it help avoid common flywheel seal installation mistakes?

Absolutely. This tool is made with home mechanics in mind—just follow the easy-to-read instructions included or watch GoWesty's helpful video guide. Unlike makeshift solutions, the precision design ensures the flywheel seal goes in straight every time, preventing costly leaks caused by crooked or uneven installations. Many users have commented on how this tool took the stress out of what can otherwise be a tricky job, giving great results even for first-timers.

What’s the benefit of the oil return hole drill guide feature included with this tool?

This unique tool not only installs your flywheel seal perfectly, but also offers a built-in drill guide to add an oil return hole—an upgrade that helps extend engine life by directing oil safely back where it belongs. This dual functionality saves money by combining two jobs in one tool, and ensures precise drilling so you don’t risk damage. Many customers find this adds real value, making it an affordable and versatile addition to any Vanagon or Bus owner’s toolkit.

This flywheel seal installation tool is an affordable version of the Volkswagen tool VW191 with a very important added feature: it doubles as a drill guide to safely drill an additional oil-return hole in your engine block.

If you are getting ready for a new flywheel (rear main) seal this is the tool to push you in the right direction. This handy piece of kit attaches to the crankshaft with the original flywheel bolts to make sure your new seal is perfectly centered. The cup also ensures the seal is pressed to the right depth so that your flywheel does not destroy a brand-new seal.

After building some 3000+ water boxers, we know from experience the oil return galleys VW cast into the block halves are just barely large enough and can easily get clogged causing the seals to leak or, worse yet: completely blow out. The drill guide feature on this tool makes it easy and safe to add an additional oil return hole—which is something we do to all the engines we build.

Works with:
• All Volkswagen Type 4 engines and all waterboxer. Does NOT work with diesel.
• 1972-79 Type II Bus
• 1980-91 Vanagon
• 1969-76 VW 411/412, Porsche 914/4

Flywheel Seal Tool and Oil hole jig

I used this tool for both the seal install and to add an additional oil return hole in the engine block. The instructions that you can access are very good. But when drilling your return hole, note the drill goes into the tool at a downward angle, something I wasn't expecting when I started. But I felt pretty good using this tool, and adding this additional hole.
