thinking about taking the engine apart

[Murphy]

i had complete gasket kit at 260k miles after the right side head gasket would not hold blew. the head and cylinders were very surprisingly clean, looked like a motor with less than half its mileage

i just wish there was somewhere i could send my oil to be analyzed, but i dont think there is anyone that does that. oh, if only such a place exsisted....

A few different places sell them but I think I got some from http://www.quickoildrainvalve.com/

I probably woudln't use the nipple version on a Subaru unless there is no chance of going off road.

Either way why not spend the extra money on oil analysis rather than replacing it? You'd not only know when it was time to change but also have a trend that would show any other problems within the engine.

I agree with you, it's at least worth sending your oil off to see how its contamination level.

As of May 2007 Subaru says "All turbocharged models are considered to be operated under severe driving conditions and require the oil interval of 3,750 miles or 3.75 months."

So the 3k oil change is even too much for a track driven STI
