Hi, I'm currently swapping a 1JZ VVTi into my mkiii and had to convert it from a front to rear oil sump. I ran into trouble when the oil return line from the turbo to the oil pan no longer fit. The return line is formed rubber and I believe the part number for the front sump is 15491-88401. I also found a part number for what is described as the return line for a rear sump, part number 15492-88401, but this line does not fit either. I've seen braided lines online but surely there is an OEM replacement part? Any help is appreciated! Thanks!
