Hi guys,

I am using a 205 block for my 4x4 Mk1 Cortina and have fitted a 4x4 oil cooler and filter adaptor. The trouble is big 27mm securing bolt wont tighten to the adaptor bolt.

When I tighten the adpator bolt to the block it seems ok.....I then slide the oil filter assembly against the oil cooler and finger tighten the 27mm bolt to secure. When I then tighten with a spanner the adaptor bolt that is screwed into block slackens and the whole assembly comes away from the block!!

Any help?

I am assuming I am using the correct adaptor bolt. See pic below of small 2wd and larger 4x4 adaptor bolts.
