Dennis,

I thought the bypass valve also served to prevent overly high oil 
presure when cold? Is this not the case? Just wondering - in cold 
weather (30-40f) using 20w50 I will get 100-120 psi of oil pressure 
during the first few minutes of driving. This is with a VW filter - I 
have not used anything else since adding the gauge, so I don't know 
if the bypass valve has any effect.
