Can someone enlighten me as to which connection is the feed and which is the return line on the oil filter housing . Just so I get them the right way for my upright 115mm 25row oil cooler behind the grill, as apparently you should have the feed entering at the bottom. Thanks.

Dont know which is which, but the reason for feeding from the bottom is so that it pushes the air out of the top bleeding te cooler. If it fed from the top the air would remain in the cooler makingit inefficient. Got some thermal images at work showing the coolant path in a cooler plumbed up wrong.Everything should be made as simple as possible, but not simpler.--:Albert Einstein -
I thought return was the nearest the block/furthest back. Can check tonight...
PS Where did you but the lines/cooler? Mine is knackered and needs replacing.Comment

Mine is behind grill, 115mm matrix and about to be uprated to 25row as oil temps on the few hot days last year reached 120degrees whilst playing with various cars on the motorway

Will let you know tomorrow. Used a thermal camera on rad and found mine is connected wrong way round with hot oil being fed in at the top and cooler oil leaving at the bottom. Will swap over and note which one is which. Assume having them the wrong way would reduce the efficiency of the rad with likely air pockets etc.Attached Files1986 Coupe q - 2281cc 3B, chargecooler, 2.75" exh & downpipe, ported head, water injection, CGR box, modified MD357 turbo, 440cc injectors, high power coil.

OK The connection on the filter housing nearest the starter is the feed pipe. Thats that sorted.
