Burning coolant, but not headgaskets?
Question about my 02 wrx. I got it about a month and a half ago, and it's been running great, but I'm having an issue. I'm going through small amounts of coolant, like maybe a cup or two every two weeks, and it's becoming a problem. I know it's getting into the combustion chamber somehow, because I can see the billowing white smoke when I push it, but there doesn't seem to be any loss of power. At first I was nearly positive it was a head gasket issue, because white smoke, drop in coolant levels (although seemingly sporadic), random stalling out, and the other day it misfired on cylinder 2. However, there is no antifreeze in the oil, and there are no exhaust fumes in the radiator. I bought a combustion leak tester kit, and did it twice; fluid stayed blue. I recently had the turbo, fuel injectors and pump changed, so I'm thinking that maybe the person who changed it didn't put all the hoses back on properly, or maybe i'm leaking somewhere? I'm at a loss here, and I was wondering if you guys could offer any insight. Thanks
