What might cause buick encore turbo oil leak?

When deterMINIng the cause of Your Buick Encore's oil leak, You should really start with the location and severity of the leak. The most common cause is a degraded seal in the drain plug, which as You'll imagine, is a pretty easy and inexpensive fix. On the other end of the spectrum, You may be gushing oil from a cracked head; that, not so easy or inexpensive. If You're looking at an oil leak from directly around Your turbocharger, then You're more than likely looking at a bad seal or a split in a turbocharger oil line. These cost around $160 to $180 to replace through most reputable shops, so it's nothing too intense. However, You should first determine precisely where the oil is coming from; until You're sure of that, You won't know how serious the issue may be.
