gimpydingo Posted July 12, 2021 Share Posted July 12, 2021 (edited) I was excited I got my rebuilt vf46 back from JMP about a week ago. Got it all installed and went to burp the system. No weird noises, no smoke, no leaks, I was happy. I noticed aluminum flakes floating up into the funnel from the turbo reservoir. I am thinking maybe the water pump?? I did check with JMP and he confirmed nothing to do with the turbo. The coolant has been replaced at least 5 times over 100k miles. I have never used leak stop, but did use the Subaru conditioner last time, but not this time. Edited July 12, 2021 by gimpydingo Link to comment Share on other sites More sharing options...
SubOperator Posted July 13, 2021 Share Posted July 13, 2021 Does the engine make any weird noise? I'd probably drain and flush the system to eval how much metal is there. 2005 LGT Wagon Limited 6 MT RBP Stage 2 - 249K 2007 B9 Tribeca Limited DGM - 272K SOLD - 2005 OB Limited 5 MT Silver - 245K SOLD - 2010 OB 6 MT Silver - 205K Link to comment Share on other sites More sharing options...
gimpydingo Posted July 13, 2021 Author Share Posted July 13, 2021 No weird noises. Everything sounds Subaruy. Yeah, I'll drain and screen too check it out. I'll flush with distilled water too. Link to comment Share on other sites More sharing options...
gimpydingo Posted July 20, 2021 Author Share Posted July 20, 2021 There were very few flakes. Pretty much all shown in the pic. I flushed/ran with distilled water a few times and filtered the contents. Anyway got everything buttoned up, took for a spin. Sounds and feels good.

Keyan Posted July 20, 2021 Share Posted July 20, 2021 i wouldn't worry about it unless after cleaning it you see it a second and third time Link to comment Share on other sites More sharing options...
gimpydingo Posted July 21, 2021 Author Share Posted July 21, 2021 My thoughts exactly. I only found 1 other WRX owner that mentioned similar flakes with no resolution. Now if it was the oil with flakes... Time to break in the turbo! Link to comment Share on other sites More sharing options...
