hi maxlee... sounds like you've found the centrifugal oil filter.. its behind the right hand drive belt pulley.. to get the back panel off the car is easy enough but a complete bar-steward to get back on!!
see pic of mine bolts removed and filter cleaned, youll have to copy this link in google:
http://images.ofoto.eu.com/photos131/7/69/21/19/88/0/88192169733_0_ALB.jpgthe bolt that sits through the big compressed spring is a nightmare to locate under the exhaust manifold and tighten down at the same time and you'll never do it on your own! (in the end i used those plastic ties you can get either side of the spring and tried to compress it!)
don't know how you'll get the filter cleaned without removing the rear apron, so make sure you have the engine well supported on a trolley jack because everything goes once the bolt is undone!
i used gunk to clean the filter and replace with a new seal,then tighten the cover back on, i bought millers oil, i think it was 20-50 classic, good stuff..
you may have read my post about gearbox oil.. make sure you can get the
filler plug undone before you drain the gearbox oil out! it's located towards the engine obviously higher up than the drain plug which is clear to see.. the drain plug is a 12mm square socket attachment, the filler plug needs a 12mm female square drive socket or as 'Cars' mentioned the reverse of a 1/2 inch socket drive fits!
again i used millers gearbox oil (not hypoid) just a 70-80 grade..
hope thats covered it.. good luck!! :wink:
