Hi all,
owner of a September 2016 FGX xr6 turbo. At the start of the year I was doing stage 3 upgrades to my car including everything that comes with doing the oil pump. The only thing that wasn’t really done was the turbo itself being upgraded. I’m only running at 340rwkw just for some fun and without putting too much pressure on my gear box. This was done in February 2020 and it’s now June and for a few day’s my turbo has been making such a horrible noise. On starting my car it sounds high pitched and after the first blow off valve release it’s no longer high pitched but “dry” sounding. When the car is off the turbo is still spinning and sounds like it’s grinding away for roughly 30 seconds before stopping. I asked a mechanic and they said it’s being OVER supplied with oil because when I put the new braided oil line in, I didn’t remove a filter in the block, I wasn’t even aware I had to and would an over supply make it sound dry? I’m very confused as to what to do next. I could Always buy a new turbo but I don’t want to run the risk of this happening again and wasting 4/5k.
Thanks heaps for any help.
