Oil pump strainer wasn't anywhere near as bad as I was expecting though.

Total job took about 6 hours, working slowly. Real pain to get access to the drain and fill plugs and get the oil pump off.
Still, the oil was definitely due a change, the car has done 34,000 miles. There no way this unit would survive 100,000 miles without an oil change, the grit and debris from the clutch friction material circulating in the oil would destroy the oil pump.
