Since I'm pulling the motor, even though it's pretty new, it's leaking out of the front and the rear, so I figure I might as well reseal the whole thing while I've got it on the stand. I know the rear main seal can be tempermental, so I want to install it right the first time. However, I saw these simple tools were crazy expensive. I found this setup from a company:
Anyone have experience with this? At $95 including the Fel-pro seal, it's a way better deal. The metal ring is just an optional sleeve it comes with in case you have grooves on your crank, which I shouldn't.
Holy crap, even used those are crazy expensive. I found a couple variations of that tool. It looks like maybe they're older version of the same tool?
One it the J-35621-1A
The other is J-35621-UPD2 which means update #2. I can't find a picture though. I could grab either of these for less then $70 which is half of a used ebay version of the -B model. Anyone know about these?

The Teflon one you use the plastic sleeve and use a wide punch and or small hammer to tap it in, no oil on install
The rubber one you oil and just use a wide punch like previous post said to drive it in
Last time I saw one of the KM tools on ebay it was exploding wallet but if you find one cheap well worth it. Very plug & play for RMS install
Don't make this more difficult than it needs to be. The RMS is about the easiest seal to replace.
Sorry, I just hear a lot of stories about it not being installed right. I'm sick of having an expensive, built motor that leaves oil everywhere it sits. Since I'm pulling it, I just want to make sure this gets done right.
Just get the rubber FelPro RMS assuming your leak is from RMS.
You can see in the pic below there are 3 slots to use a screw driver to pry the old one out. Then just oil up the new RMS and slide it over crank and tap gently around the seal until it is flush with the RMS adapter. Very straight forward
Yeah the tool is very plug & play to install but this is one seal that itself is really easy to install without the Kent Moore, or clone, tool
