oilcooler seals S90 engine

Morning All

Noticed a bit of a oil leak from my engine yesterday so dropped it out last night as i had to clean it up and do some other jobs anyway.

I found that the oil cooler was leaking from the seals, the seals look fine and the cooler was bolted up tight.

After doing some reading i have found that some people say use VW cooler seals not the one's in the rebuild kit and also some poeple use Viton seals to.

have you guy's had any experience ? the rest of the engine seams oil tight after the rebuild it just this anoying leak from the cooler.

After reading into it all im wondering which ones to go for.

Cheers
