Fuel in oil?!

Fuel in oil?!
Downed my 1994 Rx7 that was fully rebuilt professionally 8,500 miles ago.
Downed it to do non sequential conv., emissions delete, silicone vacuum job, also intake/intercooler/exhaust upgrades. Another problem I was having was getting excessive fuel in my oil.
My car has been off for about 6 weeks now. I pulled both fuel rails and changed the oil afterwards. Now, 4 days later; I can smell a decent amount of fuel within the oil again.
I'm stumped. I thought it would've been either leaking injectors or running extremely rich. However my injectors were sonic cleaned as part of the rebuild. I was having CEL 17 (o2 sensor).
I'm completely confused now though.
Can anyone shine some light possibly?

Was another thread really necessary? ---> https://www.rx7club.com/3rd-generati...l-oil-1040943/
I think some other causes for fuel dilution (other than leaking injectors) were discussed anyway.

Side seal being the only questionable one but it was rebuilt not very long ago with everything being replaced.

Had a more reputable builder take it apart and he said the irons were out of spec.
I also had a crazy amount of fuel in the oil. No way to know unless you take it apart and have it mic'd.
