...I have done RMS in both IDI and PSD's....and all ways went with FERD parts....
The PSD RMS is teflon and you DO NOT oil it! It "did" come with a plastic installer sleeve...possibly because I bought an oversize seal/sleeve kit.....
If memory serves, the sleeve did not look like it seated deep enough using just the install tool but when you install the flywheel...it pushes the sleeve to proper depth......
Hope this is of some help
