Hi All,

  A question: what thread sizes are being used for coupling to remote oil filters?    The reason I'm asking is that someone had commented on the filter bypass block I put up last month.  So I made a set of "blanks" that could be finished in a variety of ways per the suggestions/requests I got.    The block pictured isn't finished (as you can probably tell from the Dykem still present), but is set up as a diverter rather than a bypass. The inlet and outlet of this piece are currently drilled for 1/4" NPT, but not yet threaded.  It could easily be converted into a bypass block with two sensor ports merely by drilling through between the existing inlet and outlet. The most forward blank face (in the photo) can be drilled for an additional port for a pressure or temperator sensor, and there is room to put more taps in on other faces.

  I'm still working on the 120* filter adapter that I ultimately intend to use on my COZY.    Of course, those of you who are running engines built by BT can't use any of the above, since the filter mount pad is no longer there.  I have some ideas for that, too.

Regards,
Dale R.
