A while ago, I mentioned the possibility of powering my '90 Loyale with a junkyard EA82 Turbo motor, and said that amongst the possible problem was a design fault in the turbo oiling.  I was pretty promptly corrected for saying that, and since I couldn't remember where I knew it from, didn't pursue the matter.


Just now, reading the Amsoil site, I found this"


has published Service Bulletin # 02-103-07 that identifies a factory
design related problem with premature clogging of the oil mesh screen
located inside the oiling system that supplies the turbo charger on all
model turbo charged cars. A clogged screen will result in oil starvation
and turbo charger failure. Subaru has since published Service Bulletin
#02-110-10R indicating that 2010 MY and prior turbocharged engines
continue to require oil and filter change intervals of 3,750 miles
(6,000 km) or 3 3/4 months, while all 2011 MY turbocharged engines have
returned to the original requirement of 7,500 miles (12,000 km) or 7 1/2
months, and they are required to use synthetic oil. Due to the issues
outlined in this document, AMSOIL recommends following Subaru drain
interval recommendations."

That service bulletin is for the newer models.  I believe post +06 models with active valve timing/lift.


The old EA82t oil line has no screen in it.

Yeah that's for the newer ones. Seems the 05 Legacy GT's were the biggest victim of this issue for some reason.
