What is a broken wastegate?
#5
My car has had engine trouble and was parked for 6 months. I drove it down to Crazyred in Sacramento (90 miles). Keep in mind that the car has not been down the road for a while, it burns oil and fires flames. I noticed some oil leaking out of the intake pipes after the intercooler and I wanted to track down the leak.

You have two options, get or build a oil catchcan, or put a small filter on the crankcase breather. Either way, clean out that oil mess, do one of those, then see if oil still get into your IC piping. If so then your turbo seals are bad and you need a turbo rebuild which you can do yourself with an $80 complete rebuild kit. If oil is no longer a problem then you know it was coming from the crank breather and a catchcan will solve that problem. It's good to route vacuum to the crankcase, it relieves pressure in the motor allowing oil to drain more freely into the oil pan.

It depends on how it breaks. If the wastegate door got frozen/stuck shut somehow, yes, you'd boost to infinity and your engine would go boom, if you weren't paying any attention whatsoever.
But with all the pressure against that little flapper, I find that an extremely unlikely failure mode.
