SOURCE: noisy lifters?
some anti freze may have entered the oil when repairs wrer done, check oil first, but the 3.1 has solid lifters and is a comon problem to make ticking noise, the lifters are about $60 each x 12, my friends olds 3.1 has made that noise for 10,000kms now, wreckers may be an option

step 2Remove the intake You'll need your screwdriver to loosen up any clamps. You really only need to remove the section that bolts up to the TB -- this just makes working faster. If you d…
step 3Remove Solenoid I think its an EGR solenoid - regardless, its bolted on to the side of the valve cover. If you can unplug it - be my guest. I couldn't, so I used a socket and unbolted it.
step 4Remove Spark Plug Wires etc. Pull the wires. Also disconnect the PCV canister and breather hose.
step 5Remove Valve Cover Bolts and remove the valve cover Using the Torx bit, remove the valve cover bolts and their gasket washer ring thingies. I think they are all the same size, so no worries about keeping them in order. Th…
step 6Optional - **** out any oil If your gasket failed like mine, you're gonna need to pull some excess oil out of the plug wells. A plastic turkey baster comes in handy here :P I used a pipette - it is wh…
step 7Clean the Mating Surfaces Using the gasket scrapper, remove any and ALL of the old gasket material. Using a #1 (or maybe #2) flat head screwdriver will help get the old material out of the groove…
step 8Apply the RTV Gasket Material Follow the directions on the tube of RTV. Evenly apply a bead of RTV sealant on the valve cover. I added a little extra to the #1 and #2 spark plug well. I did this because…
step 9Put the valve cover back on This is important. Place the valve cover back on the head exactly where you want it without hitting anything. If you smear the wet RTV, you're going to have to clean it off…

You are not letting them bleed down.
The lifters will stay "pumped" for some time after the engine is first started. Sometimes its so bad the engine won't start (if fully pumped). If the engine won't start, you can cycle the engine by hand and compress the valve springs and let it sit for a time and they will bleed down (a couple at a time then turn 1/4 turn or so and wait again), but the easiest way is to run the engine at zero lash and tighten the rockers to spec. (one CYLINDER at a time) and let the other cylinders run until the miss goes away. When the miss goes away that cylinder will be at adjusted zero and you can move to the next cylinder. The thinner the oil the faster it will stabilize (which means engine hot).
If the engine will start at adjusted (but pumped up) lash, just let it run. It could take up to 30 minutes for the lifters to leak down.
Lastly, you can pull the lifters out, remove the snap rings, remove the plungers and drain the oil. Reassemble the engine with "dry" lifters, adjust them static (engine off) then start the engine. After the engine warms up they should fill with oil and run normally.
If you don't know how to do any of this, you probably shouldn't be in there to begin with. If you adjust them incorrectly you can damage your engine.
Some engines have no adjustment and those you just have to wait to stabilize. If they won't start, you turn them by hand and let them bleed down.

No just yet before you go to all that expense and trouble. The lifter may just need cleaning. Go to Advance Auto Parts and purchase a can of Seaform Motor Treatment. This is not an oil additive. This is a fantastic product that just may clean your lifters and stop the noise. Read about it here and watch the video. You put it in the crankcase as per the instructions on the can. You can also get it at other retailers and marine supply stores. http://www.seafoamsales.com/motor-treatment/index.html
