Wife's car has developed an oil leak from rear crank seal, so went for the flame trap rather than pull gearbox etc off to save my already buggered back.

Is there a trick to getting this thing out? Its hidden down on the block, under the manifold and the spaghetti of wires and fuel lines. Unplugged a heap of stuff but still can't get fingers (or anything else) in enough to move it. Does it just pull out? I assume it has the same wound metal filter/trap thingy inside and will respond favourably to a good flushing, the same as the earlier (and much easier to service!) ones .

What in blazes possessed them to put it down there!
