advice on mk1 ET oil filter mounting

[umpkin]

Edited***

afte5r checking, yes that correct, mine is mk1 engine has sandwiched oil cooler, after looking at FAST at the mk2 engine, i see the difference, and my old mk2 engine was like you say.

the fitment on the mk1 engine is, you fit the oil cooler to the block with a long hollow extension piece, that tightens up the oil cooler to the block, once tight, you then screw on the oil filter as you normally would.
