First mod, Banjo filter removal. This is the #1 reason Subaru turbo's die often, second reason is Up pipe cat that breaks up over time. For some reason Subaru thought it was a great idea to put a fine mesh filter into oil lines for turbo and AVCS (cam timing advancer).
AVCS filters are the easiest to get to, so check them out first.
Interesting, no AVCS filter, my 04 Forester XT had filters, but I do believe 05+ FXT's don't have them, maybe 05+ LGT's are the same?
Trust but verify, dig around in the AVCS oil hole to make sure the filter is not in there, on my FXT, both filters fell out of the banjo bolt and was inside (hard to spot since they are black like the oil).
Turbo Feed/AVCS Feed
This one is the most important one, if these get clogged say good bye to your turbo. My cars turbo was replaced around 90k miles. I was worried that the shop that did it either didn't replace the filter or remove it, most turbos go out about 10k after initial replacement.
There is a bracket that bolts to the up pipe and to the block, needs to be removed
Then you can see the oil feed banjo, sadly only a 17mm wrench will fit, ratcheting wrench will make your life easier!
Filter is still in...
, pull it out and install the bolt as is. The hard lines have a built in restrictor for the turbo.
Took the current filter to the light... doesn't look good. I could still blow air through it, but it's definitely a restriction.
