I bought a new set of Felpro valve stem seals for my 1987 Supra and I noticed that when I installed them they took very little force to install. I basically dipped them in oil and inserted them into a 10mm socket and extention. I then just pushed them on. They went on with 1 click and with VERY little force compared to how much it took to remove the old ones. Is this normal?

Yes the old ones harden and basically glue themselves in place two clicks. I would say that it feels like a couple of pounds to push them
