Gloyale how right you are. I think....forgotten what I found with part numbers in factory listings. Inlets different to exhaust. But one was upgraded or superceded in 87?

 

Resolved the issue buy getting a set of each on offer from Rock and the last odd one for giggles I suppose.

 

Jesz, metallic core and just seal and its spring at the top?

 

One term used somewhere was "positive" type.

 

No idea

 

Turbo inlets are gonna be subject to pressure like suggested above for exhaust.

 

Nitrile is regarded as old school cheap, then there is another that escapes me, then Viton which is what good needles are made of in carby seat talk.
