G'Day grumpy,
Well, more pulling down reveals that the filter comp. unit on the oil pump inlet was a loose fit in the oil tank - hence the leakage of oil. It does not seem to be a very tight fit even when pushed home - no evidence of an O-ring. (See Item 48 on Fig 1 in the G3800 Parts List). All lines are clear, but the pump is buggered. The crankshaft-driuen worm wheel is OK, as is the pump worm gear, but the pump screw section does not rotate with the worm. Must have sheared off or something. I need a new pump.
I have a question - the oil tank breather assembly does not at all resemble the system shown in the G3800 Parts List,(as Items 17, 18 of Fig 2). What is fitted is a short vertical plastic tube rising from a nipple fitting on the tank front wall and is terminated in a self-tapping screw. There is no visible opening anywhere on the tube or the screw - so how can this breathe?
Back to work.
Regards.
