Dave,
    Would this be the valve you are using ??.............(12 volt, Normally open, Hi Temp seat)............
Do you remember which of the Hi temp seat materials (EPDM, FKM or PTFE) was recommended as best suited to the hot lubricating oil environment ??............Also do you remember what orifice
size you used??...............I do seem to remember that a restrictive orifice was recommended in the
feed line to turbo chargers to reduce pressure and volume of oil so as not to push oil past the turbo
oil seal ??...............
 
 
Thanks

They are not really set up for the small guy, but they were nice enough to me.  Special order, took a couple of weeks.

Hey Dave;
This idea of an oil shut-off at the turbo appeals to me, how did you do it?
