On fitting the BOV (not got RIP on yet) I noticed a residue of oil inside the silcone intercooler pipes where it leaves the top of the intercooler and goes round the bend into the plastic part of the pipe. Just a trickle that had gathered at the bottom. Is this suggestive that the oil seals are on the way out on the turbo (as I suspect) or is it normal to have some oil vapour buzzing round?
The silicone pipes have been on for about 18 months.
