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
