So for a while now my car has been whining loud when I hit high boost, it's weird because it only happens in 1st and second. Anyway. I decided to take a look at my turbo and exhaust manifold. I discovered the 1st and last exhaust manifold bolts had snapped off. So I gotta extract those. Upon inspection of my turbo I noticed a weird hole inside the compressor side housing.I have attached some photos. Is that supposed to be there? Or is my turbo actually f**ked. The funny thing is if it is screwed I haven't noticed any change in boost.
Anyways thanks for reading
Cheers
