the thing on the oil filter is for the oil cooler.
its a little bypass thing. to run oil into the cooler. Don't quote me on that. wait for someone smarter to turn up.

oh here the thread about oil coolers from a few weeks back.

right the thing on the oil fiter IS and oil to water cooler. if you have that then you don't need an oil cooler as far as i can see. just found it on page 424 of the vizard book.
quote from picture
"shown here is the oil to water heat exchanger used on the MG metro. the unit is positioned between the oil filter housing and the oild filter and is mounted with the longer stud type filter..."
edit again,
also from looking at the oil cooler you have it fits between the filter and the block so it would replace the oil pipe painted red. but you have the heat exchanger ... ... so i can't see the point unless your going for alot more power. i mean if oil temp worries you plumb in an oild temp gauge. Then you can see if you oil needs it. but with winter coming you prob won't for now.
