You want it done "right". Look up what mazda uses, and copy them, they sold these by the thousands. They use their version of grey RTV.

Also, in your pic in the top post, it looks like the seal is also hanging out on the right side, it it? Looks to me like you just used the wrong seal, and it's way too big.

Fool proof install: Buy mazda seals for your year engine/pan, follow mazda instructions using mazda sealant.
The first picture was the FelPro gasket, it fit really bad. Then I got the gaskets from mazda, and the small thin outside edges pushed out, causing the leak.

I went back and read your post in my other thread, but you don't state weather you let stuff dry first, or what. I understand that this is a pretty simple install, but I have had one failure on the stand, and one in the car. So something in my process is definitely wrong.

To reiterate, my first install with the REAL Mazda gasket was like this:
Ultra paranoid cleanliness
Mazda gasket
Ultra Grey RTV
Wet layup, on all surfaces
Dried for two weeks and looked fine before engine install.

Seal squeezed out a month later.

The seal likely squeezed out while tightening the pan. If it really was fine, and then a month later it came out, that's crazy. The RTV should have dried in a few hours and that glues it in there so that could not happen. Did you use an old tube of RTV that didn't setup correctly?

When I do it, I don't wait for anything to setup.

Clean every part perfectly with brake parts cleaner, let them dry.
RTV on block where MBSP/windage tray goes
Install MBSP/windage tray
Oil pickup tube is next IIRC
RTV block and install little black seal
Oil pan goes on nice and square
Get every bolts hand started
Run every bolt down by hand
Do that again
Do that AGAIN. At this point, I've pulled the pan down using my hand twisting on the 3/8 extension, then I put the extension on a ratchet and lightly torque the bolts evenly with the torque of my wrist.

I'd say from the first squeeze of RTV until the last bolt is torqued is probably 15-20 min with a MBSP since there's more bolts to tighten with it.

I don't know what to say, except that, that's exactly what I did. I was already concerned about it, so I sure as hell wasn't monkey torqueing anything. I think this time I will do a wet layup and go finger tight plus almost nothing, in sequence of course.

A lot of times I over think these really trivial situations and end up screwing myself.
