Hi all yesterday i fitted the turbo oil restrictor bolt that reduces the oil pressure in the turbo, in to the Astra GSI belonging to my son....For all those with a gsi turbo fitted with a vxr turbo.. and those vxr zafiras.. this is supposed to avoid the oil pressure being to high and causing oil to be blown through the oil seals in the turbo, which causes Blue smoke..

here is a picture of the old and the new ...the new has the smallest hole...Note the difference in size..

i cant see how it can get blocked because its after the oil filter,,so that should prevent any blockage..
