Mine was close to as bad as yours as far as being black gunky like that and I changed oil frequently and flushed a few times. That stuff does not come out unless you use a wire brush. Trust me. I had to sand blast most off. Just pop the valves out while the head is off and use some lapping compound andreseat the valves along with new stem seals. They come in the AB head gasket kit. The valve covers are a nightmare to clean. I didn't do anything to my head bolts... just used a breaker bar to get them loose.

For sure not anyone, I overestimated myself few times, I hope i am not going to do it again
If I follow your example, my wife will be very happy.

I literally just got done doing mine today. I said screw it and tore everything down. I didnt have the $ to send my heads out tho so I just put new stem seals in, sand blasted them, and relapped the valve seats. Very happy with the job and how well it runs now. I'm like you... look forward to a couple of years of "trouble free" service now. I must have drank $200 in beer during the process.

In the tech section is a write up on a $50 cross ref fan clutch that fits early 2000 Chevys, the non/AC version. It will be 6 inch diameter, reverse direction, and screw right on to your water pump. Will have to enlarge mount holes on fan blade slightly.
Any idea on your oil PSI before the work?

I am now 100% complete with my break down. I finally got around to pulling the water pump and front cover.

I checked my oil pump gears and guess what I found?

I sure am glad that I went the extra mile and checked this while doing the heads. I feel justified now with all my work on this 100k mile service. If I didn't catch this now it could have been game over for my engine.
As far as I know my 01 disco dose not fall in the Vin. death range for oil pumps and this was still an issue. In my opinion (from reading similar cases on all disco's) the oil pump gear kit should be added to mike's 60K major service or at least done at a 100k mile service. It seems to be a very common problem on all disco's not just the 2003's.
I need some help finding a few part numbers before ordering everything.
1) Replacment fan clutch
2) These rubber plugs in the oil pan

Did you have any ticking? if yes, was it there only at idle when engine was warm or could you describe your ticking?
Thanks
