Subaru Genuine OE reman turbo installed.

Car running perfectly. No smoke. Quick, smooth spool. Pulls hard to redline with no issues from turbo.

Now, this is just after a few short miles of testing. Need to get tags on it to take it for a longer highway drive.

Don't buy cheap turbo parts. Just go OE from the start.

Great. What song did you crank when turning that key for the test? Haha.

What all did you do since the last failure? Looks like you’re certain it was the turbo itself?

We did drop the pan, replace the pickup tube o-ring, and R+R'r the oil cooler. And we didn't find anything of consequence in the oil pan either.  About a table spoon of sludge, but no chunks, and nothing clogging the pickup screen.


 We also replaced the Banjo bolt/screen with a brand new one.  Although that was mostly just to satisfty Subaru for warranty.  The old one had no clog, and was perfectly clear and flowing.  


I also pulled the timing covers and verified timing CAM timing.  Pulled pass side AVCS solenoid and cleaned, but found no debris or clog.  Reinstalled with new O-ring.

I am very interested as to what the shop thinks of this, they should have given you a nice refund or offer something for all the headaches

Like I said - it's going to come down to cheap turbo parts. The shop should be made aware of the outcome of the repair.

Some awesome info in this thread!

I took interest as I've got a TD05-16G turbo to strip and rebuild on my Liberty RS project (Legacy SS). I'm only doing this as the engine had zero bearing left on no1 big end - piston was slapping the head, lots of shavings in the sump and on the pick up.

My thinking is that the turbo may have some metal in the bearings so thought it best to do a replacement job and learn a thing or two as I go.

Goyale, very interesting (although very frustrating) situation that seems to point at the replacement core. Glad you've finally got it sorted pending a decent run at speed/in general driving conditions.

GD, thanks for your input and knowledge on turbos through your experience, really awesome and something that money cannot buy.

Keep the good info flowing!
