There's not enough temperature to burn it off during idling and oil accumulate in the housing. Other possible cause is exhaust valves stem seals popped out of the valve guide and oil seeping into exhaust manifold. Both causes are very bad for everything down the line ! If under easier way you mean not using wrenches ? The answer is NO . The less invasive way is to separate turbo from exhaust manifold and use borescope to inspect which exhaust valve(s) stem seal(s) are compromised. If not borescope available you don't have choice but to pull exhaust manifold and inspect . The best way is to idle at least for a couple hours. Shut it off . Let it cool down to ambient temperature, then do it . RE: Turbo squealing - Bmyetrkg24 - 07-16-2016 I hate to say it but all your symptoms are describing the exact issues I just had with my truck with a 871 in it I would have the shop do a blow by test if u got excess crankcase pressure or u pull the oil fill cap off of it while it's running and she's huffing she's done bud!
