It has taken me awhile, but I did what I'd consider to be a fairly thorough engine service. My new-ish to me, 159k mile D2 had a quite a few oil leaks, and a couple intermittent coolant leaks, so instead of waiting for it to overheat or leave me stranded, I did "All the things" as preventative maintenance...or maybe OCD, but whatever, lol.
Head gaskets - Elring gaskets with ARP head studs
Timing cover
Timing chain and sprockets
Oil pump
Speedi-sleeve on the Harmonic Balancer
Water pump - FlowKooler high flow
All coolant hoses replaced
Oil pan gasket
Rear main Cruciform seals
Ignition coils, Double Platinum Spark plugs, NGK Wires
Crank Position Sensor, with silicone heat reflective spray on CPS cover
Bosch 150 amp Alternator
ACDelco AGM group 65 battery
New split loom on all engine bay wiring
All other needed gaskets to do the job (Valve covers, Intake gaskets, o-rings, etc.)
Did a few other things while in there, but I forget what they are...
Engine looked pretty good internally, bearings all looked great. Had more dirt and crud in the oil pan than I wanted to see, but no metal. Cylinders still had good crosshatching, and the lifters and cam lobes looked great for a 159k mile engine. The timing chain and gears were a little worn, so was the oil pump gear and timing cover, definitely worth replacing them. Seems to run much quieter and smoother now, so that's nice
Also managed to score some new KYB adjustable shocks and a new steering stabilizer for cheap on FB. Thing rides much better now, lol
That's a good chunk of work! Did you completely remove the engine to do it all or did you leave it mounted in the vehicle?

Did it in the vehicle, in my garage. I'm an old mechanic, but this is my first Land Rover. I find them to be quirky, but not overly difficult. Although I will admit it took me 3 tries to get the front crank seal to stop leaking, lol (getting the speedi-sleeve positioned on the Harmonic balancer right is tricky, IME)
not all today, but over the last month or so my son, 19, and i replaced all the hard brake lines on brake hoses on the '01 Discovery. the existing had rusted out and burst a hole on a test drive after doing the Option B mod.
today we hooked up the final brake hose, bled the air out and started her up. well, tried to start her up. battery was dead after sitting for so long. my own fault as i have a maintainer in the cellar.
jumped the Rover and she fired right up. slowly backed out of the driveway and she stopped properly when i applied the brakes. took her out on the road and she drove and braked perfectly.
turned her off to check to see if she would restart. no go. so, pulled the battery and threw it on the trickle charger. we'll try again tomorrow morning. hoping i don't need to buy another new battery.
regardless, it was nice to know that after replacing the hard brake lines, thanks Rovers North, and all the brake hoses we had no leaks and she stopped the way the factory intended. first time ever attempting a brake line replacement. would have been much easier if rust hadn't been constantly raining down on me from every other surface on the frame.
Attempted, unsuccessfully, to install Rovers North diff guards, front and rear. The front guard bolted up nicely but the panhard bar was fully making contact with the guard. Apparently this is a known issue with '04 Discoveries. The rear guard I got loosely bolted up but the geometry and clearance wouldn't allow for tightening all the bolts. I sandwiched the bracket for the weights (harmonic balancer?) between the diff and diff guard, that might be what threw the geometry to the extent that it wouldn't fit.
Did the @Best4x4 PCV mod today. I could not find the part number FV308 pcv anywhere in stock. Has to use the old Hollander exchange for part numbers and got a Beck Arnley 045-0264 for 10 bucks off eBay. How long do these pcv's last? Is it worth trying to find a spare before they are discontinued completely?
