Hi,

I have not been very successful with my oter turbo posts, but I noticed something today that bothered me greatly. I will attempt to explain it as well as possible:

-Loking at the turbo on a w123 car, from the passenger's side, you will see the u tube boing from the air cleaner, then the silver casing which holds the turbine. Going back from there, there is a narrow section and then another similar looking larger casing, which I assume holds the exhaust turbine. On the front side of this casing, there is some sort of a flange, which is held to the casing by six-sided bolts. The one in the most noticable position, directly on the passenger side is missing! I assume that there must be a bolt there, and mine has fallen out somehow, sometime.

Can somebody give me some information on this bolt, i.e what size I should use o replace it? I assume an SAE grade 8 bolt is required. Should i use threadlocker red? I could not tell (but I have never taken apart my turbo) if there should be a nut behind the bolt, or if it threads directly into the exhaust turbine casing.

I think maybe this is the caus eof the hissing noise that is coming from tha side of the car.

I hope that someone might be able to provide a bit of information regarding this bolt.

Thanks

JMH
