Cool Rear Main Seal Depth

I wasn't trying to go this deep, but one tap too many and the seal jumped in pretty far. Is this too deep, blocking the oil? I don't think I can remove it without damaging it. I don't want to reinstall my engine just to have it leak again, but I'm on a short time line. This is on an EJ22E btw, 98 OBS.

It's 1.5mm in from the chamfer, 3.5mm from the flat edge of the block.

You definitely will not be getting it out without destroying it. I'd say that would likely be ok, but if you have that doubt, it's better to destroy a perfectly good seal and do it 99.9% perfect than it is to put the engine back in and have to take it out again.

If it was me, I would try to pull it back out with a seal puller, then reseat.

Assume you will waste a $6 seal.

I tap them in with a block on the seal overlapping the engine. Tap in until flush with engine, then tap in to correct depth.

Did you lube the side of the seal against the crank? I usually put a smear of wheel bearing grease on that side for lube on startup.

I'll go to the dealership today and hope they have another gasket.

When you say tap to the correct depth, is that just to the edge of the chamfer?

I lubed with fresh oil on the inside and outside seal.

Basically want it flush with the block.

At least that's how I've done every seal on every car I've ever done a rear main on.

That's how I did my EJ25 a few years ago and no apparent issues and no major leaks.

Thanks for the help guys, dealership has one (albeit $23CAD vs $8USD from subarugenuineparts). Gonna pop this in, torque the pulleys, install the belt and covers, and it's back into the engine bay.

I get the outward flat face of the seal even with the bottom of the bore chamfer. Thus, it is slightly below the flat face of the block.
This goes for any other seal as well.
