They eliminated the rubber vertical seals and replaced them with RTV. RTV requires water (usually from the air) to cure. The wet pipe cleaners introduce the needed moisture.
I've used a couple of them. They seem to work just fine.

Yes, on the 400 I rebuilt a few years ago I used that kit. It seemed really odd to me too, but I followed the instructions and it doesn't leak. It does looks pretty crappy though and the RTV really gobs outward toward the main cap. Make sure you push the pipe cleaners all the way down too. When I squeezed in all the RTV I could down the side channels, I could still see light coming though near the bottom when I checked with a flashlight. After pushing the pipe cleaners down it seemed to seal. I also RTV'd the retainer to the block from the back as well. Like I said it works, but is pretty messy.

Wish I knew about these when I rebuilt my 440 a few years ago....had a rear main seal leak immediately after break in. Decided to change out the stock retainer for the billet aluminum one Mancini Racing sold with the o-ring side seals with engine in the car....STILL leaks

I went with rope and felts? ( or whichever material is ) seals, stock pieces from an Old NOS kit and working great by now.
Of course I helped a little bit FILLING WITH RTV the outside face of seal retainer with block ( the Groove left there )

Here's a pic of them installed. This is the previous design (different color for identification) Both are very effective. One is just a little easier to install than the other and come with complete instructions
Very nice design. I hope you get your website up soon.

I bought the same billet seal housing from Mancini. Mine leaked as well. When I took it apart, the problem was clear. When you slide the housing with the side seals into the block, the little rubber seals stretch. Over time, the seals pull back. I had a least 1/4 gap at the bottom of each seal. I had cut them off flush when I installed them. I got new seals (didn't want to spend more money on another housing). This time I added RTV into the grove before I installed the seals. Hopefully this will keep them from pulling back. I also waited a few hours before I trimmed the seals flush, maybe gave the seals some time pull back. From the back of the block I also RTV'ed the seam between the block and the seal housing. I haven't fired it up yet to see if this worked.
Nothing worse than having a re-done car and engine that leaves oil everywhere you park.
I know what you mean...
