I’m gonna blame myself for this one. Wastegate bolt backed out and came loose, pressed up against the engine block and bent itself.
New bolts and gaskets were $10, an hour of labor to loosen the manifold and get the bolt out later, its fixed.
Since he was gonna be in there anyways, I had my tuner build me new stainless steel oil cooler lines and slice up the former passenger side fog light housing some more to make a better channel for airflow to the oil cooler.
Runs like a champ now.
