If enough leaks by the oil pump while sitting, it will eventually go thru the pinion bearing and overfill the flywheel side. BUT the only way it can or will migrate to the primary is via the seal/spacer or the bearing insert loose in the case for which there is no repair.
Either way, it will only migrate to the primary when the engine is running.

I'm leaning to the cast in insert going bad, 88 was a bad year for that issue. Seal alone would manifest a bit differently than what I'm reading so far. It was that bad oil would seep back into the crankcase sitting over time.

I had the same issue on my 92 flhs- not an oil pump issue. I changed the crankshaft seal- twice- still pushed oil into the primary. Turned out to be at the stator hold down bracket (plastic bracket with two little screws that screw into inner primary). The little screws backed out- the holes behind the screws arent blind- they go into the crankcase. My advice- change the crankshaft seal- and make sure those little screw holes are sealed by the screws and some sealant- and that they're tight.

Might be overkill but I was always told to replace the seal AND the spacer at the same time.

Might want to look first. On a TC, the seal runs in the center of the first half of the sleeve. And yes, if there is a lot of miles, the soft especially rubber catches the grit and laps a groove.
On a a TC just turning the sleeve gets you a new unused area.
For the first poster... It's probably just what you said but....
I once saw a EVO that was cracked from bad castings in the area were the bolt face hooks the inner primary cover to the engine allowing oil transfer.

I suggest you stop trying to be a moderator. Now if you like, PM a community leader and suggest he tell me that. Here he is. @djl
If he tells me my post is wrong, I will most certainly apologize to the first poster and the USER I quoted
Here is what I am referring to in a EVO . And it sure appears sleeve is designed to be flipped if it is not already been done and then it will have two grooves.
You need to keep in mind some of us are learning on here and entitled to a opinion.

A cracked stator lip will not cause oil transfer between the engine and the primary chain case. Bear in mind when posting here that bad advice is much worse than no advice.

The problem is that if you are learning in here, you should not be offering opinions. This is one of the things that frosts me about this forum. Someone asks a question about an issue, and all the goobers offer opinions, rather than facts, and they don’t know WTF they are talking about. This reply is not opinion, it is factual.

I said about the seal sleeve to check. But I looked and it appeared to be like a TC and I had turned one around there. I would rather do that using the original sleeve than a new one may not be the same exact length. The cracks are also a factor to look for. You don't want to replace a seal only to have it still leaking from a crack. Google EVO case crack. Also saw it on this Forum.
I'm sorry you expect 100% accuracy on where the first poster's leak is from with one place. The first poster had already pointed to the obvious. I pointed out one other, and about maybe being able to flip the sleeve.
That is factual. Now where it actually is leaking, the post here has to be an opinion.
You like Twist need to stop trying to be moderators.
Now I do apologize to the first poster, the sleeve appears to have a flange.
