[s-cars] Bypass valves - Which one?

[Mihnea Cotet]

Yup Scott, agreed, but what about using a catch tank with a return line to 
the oil pan??? A friend of mine from the UK with a 400 HP S2 has done that, 
the idea is excellent as the oil consumption is reduced to almost nothing 
(barely what gets burnt in the chambers due to tired piston rings).

Just a thought...
