The are a couple of places that i know it could be burning from... rings, turbo, or a head gasket... if there are any others i should look at please let me know... also i know for the rings you can perform a leakdown test, which seems like it will be infinatly harder than my MR2's, however i dont really know how to check if its the head gasket or the turbo... if you know of any way to perform this please let me know! also if there are any other places that i could be burning oil from that would be appreciated... i dont know of many motor issues with the WRX, but i also havent researched it much, some insight would be much appreciated!
