         I've been away for a couple of days, so you may have had this answered already.  Skip recommended I call Pacific Oil Cooler service ( http://www.oilcoolers.com ).  They were very knowledgeable and can probably provide the info you need.
         Scott and Skip, I finally got a chance to pull my cowl and unfortunately (in my case), I already have a Stewart Warner.  I called Pacific and ordered a rebuilt model, and I am going to return mine for a core charge credit.  Hopefully mine is all carboned up and a rebuilt one will solve my problems.  I will keep you informed.  It should be here on Tuesday.  I am going today to go ahead and drain the oil and remove the old one.  If this doesn't work, I guess it cowl hacking time.
