I was having probs with my turbo to manifold bolts aleays loosening due to expansion and comtraction sue to the wide heat ranges involved and spring washers lost their tension and Wiz bolts didn't fare any better and finally stumbled on them and now problem solved.
Here is a video that clearly demonstrates how effective they are .
PS I have also changed the manifold studs to hi tension Allen head cap screws and made a tool that allows far easier tightening where it was difficult to get much space to swing a spanner.
The other benefit of the cap screws is in the event of a leaky gasket it will be far easier to replace the gasket as itr will be able to bw removed without having undo the dump pipe and having to LIFT the turbo over the studs to remove and replace the gasket should it be needed as I will be able to slide the old out and the new one in easy .
