ljf12 Donating Members 20 Member For: 13y 10m 4d Posted 11/07/14 03:39 PM Share Posted 11/07/14 03:39 PM I fitted a braided in line filter kit to an FG, oil was getting past the turbo seals. 1mm restrictor fitted in the line dropped the pressure to recommended levels, no more problems with oil past the seals. Obviously not happening to everyone. Link to comment Share on other sites More sharing options...

Doesnt sound right to me Link to comment Share on other sites More sharing options...

Doesnt sound right to meI could be mistaken but I am pretty sure that this is what the manufacturer is telling you to do. I only went down this path because I was having issues. When you consider that the vast majority of the time your engine revs would be under 2000 (prior to fitting a restrictor hot pressure was 45psi @2000), I don't think that higher pressure at higher revs is a problem, I don't think you can damage the seals. From what I have read providing oil is not getting past the seals you have nothing to worry about, but if (like me) oil is evident a restrictor might help.With ball bearing turbos Garrett do not appear to have any interest in flow rate only pressure prior to the turbo, it is my understanding they need very little oil to operate.

***VX*R8*** Member 202 Member For: 11y 17d Gender: Male Posted 13/07/14 07:40 AM Share Posted 13/07/14 07:40 AM I did this today. This thread was a huge help. I ended up doing it from the top and was actually surprisingly easy (2011 G6ET). Hardest bit I found was getting a full size 24mm spanner to hold the line still.I have an Earls Stealth Oil Feed Line & Filter but decided to just remove the filter and leave the original line on.!!!THANKS FOR THE WALKTHROUGH!!!

I left mine in there when I did it but am thinking now that its useless and poses the same issues as to why it was replaced in the first place lol Edited 28/07/14 02:04 AM by GUN-808 Link to comment Share on other sites More sharing options...
