Toyota Valve Stem Seal Seating Tool

thingiverse

Update Update: I purchased the Monkey Wrench Racing seals and the intake and exhaust are just ever so slightly different in diameter with the Exhaust being almost .5mm larger OD. So I have attached both an exhaust and intake version. Both have embossed text to differentiate the two (in = intake, Ex = exhaust). I'm not sure if the OEM seals are the same but I do know that the OEM seals do vary exhaust vs. intake. For FYI: Exhaust tool ID: 13.15mm Intake tool ID: 12.75mm Both spring collars are the same OD. Note that my printer's resolution isn't the greatest, both of those ID's are .4mm larger than the actual OD of the seals. I am attaching the .step files just in case you need to adjust for your application. I used a rubber mallet to give some loving taps to fully seat the seals. Valves are in place and the seals are nice and straight. Update: OEM vs. Aftermarket collar springs differ in size. I updated the through hole to be larger for certain Aftermarket collar springs. I saw that minus an official tool some people recommended a socket that fit the seal. I wasn't having luck with that so I made this to ensure that the seal would seat correctly and evenly. I used it on a Corolla 1ZZ-FE but from the part fitment for Toyota OEM seals this should work for almost every Toyota engine since they use the same seals throughout. This is designed to have a slight interference fit with the seal so it would hold it in place while I positioned it over the seat. It might need tweaking for your printer to do a small interference fit. You could also try adjusting the scale in your slicer to get it to work. I printed at 15% and it works just fine. I haven't done all 16 valves yet (waiting on replacements for the ones I mangled). But I will update if there are issues. 15% feels pretty solid. I designed this in NX but I am attaching the step file if you need to make adjustments for your particular valve stem seal. If you would like or need a different format, just let me know and I can add that as well.
