What part is leaking? Is it around the crank seal (hope not or it will fuck the clutches couch) or by the oil pan? The RMS should of came with a preinstalled white cup that serves as the "installation tool" . It needs to be installed BEFORE the oil pan... so to fix that you need to pull the pan.

Its at a shop right now so im just trying to gather info. I haven’t seen the leak but was told about it and was just wondering how many ms owners have delt with it.

My first rear main leaked on my built motor because it was not installed correctly using the SST that comes with the new rear main seal. It did wipe out the clutch from oil getting on it.
It needs to be Installed with the included SST using these steps
It can be installed with the oil pan attached

Ok so how did you know it was leaking in the first place?
Edit: ok so the rms has a lip and if the oil pan is installed and sticking out the lip wont let the rms sit flush. So redoing the pan may be necessary. This is why i ask where it was leaking from.

I'm assuming you're talking to me?
I knew the rear main was leaking because oil was dripping out the weep hole when the car was parked.
As far as how I know it was installed. Improperly... This pic should explain lol
A new rear main has been installed, it no longer leeks at the weep hole between the trans and pan

Ok well what happened was originally a crack in the bell housing and then they saw the rms was leaking after the trans was replaced. Motor only has a couple hundred miles so it was probably installed incorrectly obviously.

Hello mates
I am sorry I need to revive this thread as I am having the same issue, I bought the seal from Mazda in the USA despite I live in Australia, and it came without the alignment tool, I was told it does not come with the alignment tool anymore, however without the alignment tool and just sliding the seal on will result that the brown seal lip pointing outward away from the crank but It has to be pointing inward toward the crank hence the need for the alignment tool, now I am desperate to get that tool (this white plastic piece), can you advise please as some people told me that you can install it with the lip pointing outward but I am scared to death to do that then get shocked with a leaking seal again.
Cheers
Hello mate
I would really appreciate if you sell me the alignment tool, that white plastic thingy, I live in Australia and would be happy to pay you the price you want for the tool and the shipping cost to Sydney Australia
Cheers

That tool was thrown in the trash the day of the install back in June of 2018. At that time, all rear main seals ordered from mazda came with the special service tool. So I threw it away
