98 V70XC that has leak at the turbo oil return line seal at the engine block. I tried to replace the first time by putting the seal in the block and then dropping the turbo back in place while guiding the return line into the block. No luck I dinged up the seal. Tried to replace the second time by putting the seal on the turbo return line and then dropping the turbo back in while hand guiding the return line into the block. Thought I had it this time but upon driving I am leaking again so must not have gotten the seal seated good. Does anyone have any suggestions on proper way to install the seal or a way that has worked for them so when I go for try no. 3 I have a better chance of success?
