^^^ This adapts 5/8"-18 To 3/4"-16 thread, which won't be a whole lot of help for the Duratec's M22-1.5 oil filter thread. I think these allow one to use modern filters on Austin Healeys and other old British Leylend exotica. :laugh:
We'd talked about that before. I kept my CSVT oil cooler and stem intact to put on the 3L in my '08 Milan Premier. I sense that svtfixer is on a budget, and toting that stem to a machine shop, fixturing, doing a cutoff and threading operation is about an hour of operator/machine time, and the small machine shops I deal with regularly are running >$90/hour, so...
Stock cooler isn't really a cooler. It's a heat exchanger. I cant imagine how 200+ degree coolant helps you oil stay cool, it does however get the car to operating temp sooner.
So, to install this sandwich to the block, you'll need an M22-1.5 to M22-1.5 straight thread pipe nipple, these are very hard to find, but I made one from a pressure washer hose connector, you'll need to chuck it in a lathe and machine off the wrench flats so it fits properly.
