Hi,

I did see this mentioned on a video on youtube so I'll have a look. What really puzzles me is why the issues only happens at high altitude and not at lower level. I would have thought any crack would results in constant issues surely?

The crack is very narrow. Heat and air pressure affect how much boost is going thru there hence why it's intermittent.

I did 1000 miles on a split manifold till i got fed up of it! __
