I bought some studs (90106924) and nuts (90423027) for the head to turbo manifold. The Nuts are 28mm Cylinders with 7mm hex key, M8 thread.
However, the studs are too short, you get 1 turn of bite.
Studs are 39mm end to end, including the bit that goes into the head.
The turbo engine had 8 of the nuts the std Cav coppered M8 with built in washer, and about 4 of these funny cylinder things. The Previous owner had made their own studs from M8 threaded rod. Manifold & turbo is totally std KKK.
This is very strange. Do turbos normally have these special nuts???
I even went to another dealer and bought another stud, and was given the same part no. What is going on???
I am stuffed at the moment, with the car in bits.
