So I recently acquried a new to me GL wagon. I am the third owner of the 180k beauty. I caught a break with it only needing a new speedo cable and fresh set of tires. However, there is a slight oil leak developing in the driver side head gasket. It may be a stupid question, but alas, I must ask; is it worth the time and effort to mount the turbo heads on this n/a motor? Or should I just redo the gaskets and call it a day?
