Just like the tensioners. Cook at 270 degrees for about 8 hours in new oil, then pump up. Make sure to replace lifters on same valve if they pass the test. Is the tensioner in this pic the one you removed??

That looks just like the tensioner I inspected. What tensioner do I need to remove in order to take the cam gear and chain off the drivers side head?

Also what is the "test" for the lifters? I will submerge them in hot oil, but is there anything I should look for, or is there a certain amount of pressure they should be able to hold?

The 4-6 cyl. chain tensioner is on the top side of the head. In the picture below it's next to the cam position sensor. It's under the A/C compressor.
Let the lifters "cook" for a good 8 hours at about 250 degrees. Press down on the plunger to purge the old oil, you will see dirty oil squirt out, keep pumping until no more dirty comes out & the plunger gets too hard to compress again. You might need to add a quart of Marvel Mystery oil to the pot.

Thanks again for your response. I found that tensioner and removed it, followed all the steps on the pelican parts tech article and got everything apart no problem. I let the lifters cook in oil about 220 deg for an hour and I could not plunge them at all...no pump action, no dirty oil. I will add marvel and cook longer?
