Its EP90 (transfer box oil).

Defender TDI 90 - 1995 I recently did a overhaul of my gearbox (R380). After we put everything back in place, I noticed a leak between the gearbox and transfer case. On this initial job, we did put a new collar (original Land Rover part number: FTC4021) and oil seal (part number: ICV100000). Because the source of the leak seemed to be between these two parts, they were replaced yet again by new ones, however after a couple of days the leak is back. Anybody can give me pointers what can be the cause or what can be done? Regards
