Hi I am posting this thread to make others aware, to be careful from buying parts from this guy based in High Wycombe, he has sold me parts for ££££ and they have turned out to be faulty, sold me a RB26DETT cylinder stated low mileage and in perfect working order etc.. found out after wards it was warpped and incorrect caps are on it, refused to take it back, made me wait months claiming to pay back. Its happened to me, hopefully I can prevent others from this ordeal
