My 06 finally developed the deal where oil migrates from the trans to the engine a few weeks ago. I replaced the crankshaft and balancer seals and it fixed this migration direction but NOW it goes from the engine to the trans... I used OEM seals and seated the crank seal flush and not in too far. The balancer seal was easy enough so I think I got that one right also but I did not apply any grease to the outer edge first. Could that cause engine oil to migrate to the trans? should I try that one again or is it more likely another seal somewhere? Anybody been through this?
