These are not normally changed every time you take the manifold out, I wouldn't think so.
therefore I didn't order replacements - what the hell, intake is clean and cool, nothing like the exhaust nuts (that are expected to be corroded and unusable)
Well, trying to put them back on the studs, they all have the same flaw: can only go as far as their thickness, impossible to have any stud thread behind them. Hmmmm...checked them all, exactly the same flaw at the final thread. Can't be a coincidence, and it doesn't look like it's part of the design, either.
Probably the angle of the way the manifold is pulled out, who knows.
The thing is that if I tried to use these again, I'd get the torque settings alright, but it wouldn't blody seal properly, because the copper threads are soft and the resistance would come from deforming the damaged thread, not tightening up at the very end.
I wonder, could this be a reason many rebuilds end up in tears?
Inlet leaks will certainly damage the turbo!
