valves

There are articles including pictures on some sites, I've never looked for one here. If you Google "Cummins valve adjustment" you'll find at least one.
BTW, some will recommend checking the valve lash more often, but he interval for checking the valves in the factory service manual is 150,000 miles! I checked my '99 when it hit 150,000 miles, and only 1 valve set was out of tolerance. Also note, the tolerances are enormous!
I also bought a new valve cover gasket, which didn't need to be replaced (but of course I DID replace it, since I didn't want to leave it hanging on the wall for years.)
Good luck,

Make sure the motor is on TDC and start on #1 cylinder and alternate-Intake #1, exhaust #2, intake #3, exhaust #4, and so on after you get through that you rotate the engine 180 degrees and start over in opposite exhaust#1, intake #2, exhaust #3 and so on. you will need to get a feeler guage and the tolerances are intake 10-exhaust 20. Hope this helps

Once you get the hang of it , It wont take ya 30 minutes!
On the valve cover issue, Push the heater hoses down, pick the cover up and slide over the hoses. Slides right out. It's also a good time to check all the rockers, make sure the black clips are on them and make sure the rockers move freely. Also check the push rods, make sure they look good. IF YOU PULL THE PUSH ROD make SURE it's correctly seated before you put it back on the rocker ball!
Also make sure you adjust em cold!
