Leak after Racseng Cam Plate

I had a leaky cam plate on the BRZ that I just picked up, so I got a Raceseng cam plate to fix it. Even after reinstalling it several times I still have a small leak that accumulates at the bottom of the bottom corner of the plate and drips onto the exhaust manifold. I've tried installing it exactly per the instructions, with oiling the o ring, without oiling the o ring, and the guys at raceseng even recommended putting a ring of RTV all the way around the opening. They ended up sending me a new cam plate in case the first one was somehow warped, same deal.

On this most recent install, I noticed the little black rubber rib at the bottom of the opening isn't completely connected for the first 1/4". What does it do, does this matter?

Ok, I'll say it, this was THE lamest upgrade/repair part I ever spent $75 on.
When you look at the o-ring and cam facing side of the plate, you think - aw man that's nice, it lines right up with the cam profile, yay!

And then the installation reality sets in...

1. It's just an aluminum plate and the supplied o-ring doesn't do a darn thing.
2. The two dabs of grey silicone here and there (per the instructions)... don't seal a darn thing
3. You wait overnight to let it all set and then go for a drive... and oil is pouring out from the cam seams.

And then after 2 or 3 tries (each time clean and scraping) and thinking *maybe* you got a bad unit or were installing it wrong... you read more threads online like...

1. Reuse the old cam plate
2. Razor blade scrape off all the old silicone off the old plate and scrub off the old silicone from the cam port with a green dish pad and WD-40.
3. Use a Synthetic oil formulated black silicone and run a 1/4" thick bead around the old plate (following the ring pattern already there).
4. Apply the old plate (with silicon from step 3) and seat on pam port with 3 bolts BUT tighten down to about .5mm of fully seating. This will allow the silicon to slightly squish and form around cam plate, seams, port, etc.
5. Wait 12 hours. Then torque down.

No more leaks. Total repair cost, about $10.

Wish I saw this before I bought a Verus cam plate. ��

Will be going back to OEM I guess!

The o-ring on that product is basically useless, and you still have to glop on plenty of RTV.. which means you have to do a really good job of scraping all the old stuff off or you won't get a good seal.
