Hi all, I did a boost leak test at the turbo inlet earlier & found it leaks. After process of elimination i disconnected the intercooler & blocked it off at the turbo side so in theory just testing the turbo. Still leaked & found the wastegate actuator was leaking but also the air pressure was also getting into the engine. The only thing I could think is its going down the oil flow & return pipes so would this mean my turbo is shot. It doesnt smoke has minimal shaft play & minImal oil in the inlet pipe. Reading online some say normal, some say its not. I cant see how it could be normal as surely that would add unwanted boost pressure in your crankcase/valve cover. Am I missing something or has this happened to anybody else TIA
