Thanks Roy... But I think Im gonna need a little more info , If im going to find the right adapter for an oil cooler
.. I'll measure the thread incline tomorrow..
Well that 16mm diameter thread size is common to many Talbot engines, and when I got my adaptor all I said to the guy was it used a 16mm thread, and straight away he knew what adaptor to provide. If you want the pitch too I may be able to find out if I have a moment. I'll see if I can measure the thread sticking out of the block.
Roy
