hey guys, Just thought I would chuck in a little note about a potentially expensive problem I had when changeing my oil the other day. The bottom bolt in the oil filter cover(the hex key one) also doubles as a check bolt to see if the pump is pumping oil up to the filter cavity. There is a small hole drilled vertically from inside the oil filter cavity at the bottom, down to about half way along the threaded hole that this bolt screws into. I guess the theory being that you can undo the bolt to a certain point and the oil will come out around the thread indicating the pump is filling the cavity with oil. Well, as most of you would have noticed, any pieces of hardfacing or gear chips, clutch particles etc that collect in the filter accumulate towards the bottom of the filter cavity. When you take out the bolt to change the oil,these bits can fall down the hole and when you go to screw the bolt back in they get caught on the head of the bolt and rip the nice soft alloy threads to pieces as you screw it back in. I managed to resurrect my thread by running a tap through it to clean it back up and put a new bolt in it. If you feel the bolt starting to get tight before it is pulled up against the cases, undo it again and check to see if your thread is full of particles. Hope this helps!!!
