Zippy (Sonic) leaking oil

 Even though we had pretty good luck replacing the head gasket, zippy was still leaking oil. We thought we had narrowed it down to the oil cooler, so we went back in to replace that. We eventually go it out, but it took some doing, since we were trying to avoid taking out the turbo. Then we found that the stub that fits into the block was broken off, so we had to get a tool to get it out of the engine block!



We got the new one in, but had to wiggle the turbo quite a bit and it was difficult to slide it in. So it is still leaking oil, and the turbo seems to be acting up now, so that wasn't the best outcome...

Our last plan if to take out the turbo and oil cooler and make sure they are seated well and the gasket isn't bunched up. We have some new coolant and oil lines for the turbo as well that we might install if there is any doubt there. Finally we will inspect the turbo and make sure it is still working. 🤞
