The "Noisy lifter" solution
From the day I purchased it to the day I performed the following miracle (I use this word because you will too) my Talon made horrible lifter noises. Anyways here's a "low-buck" solution that's guaranteed to put a smile on your face. BTW, I have 16 new lifters for sale that I prematurely bought before trying one of the oldest tricks in the book (and now, one of my favorites).
Materials You Will Need:
1-quart Dexron II Transmission Fluid
1-quart of cold water
2-feet of Vacuum tubing
4-New NGK BP7ES spark plugs (BR7ES-11 non-turbo)
1-quart of any brand "motor flush"
5-quarts of Fresh Mobil-1 15W-50 Oil
1-New Oil Filter
First, make sure your Diamond Star is up to normal operating temperature. Find the direct-port vacuum line at the throttle body and on the driver's side of the manifold (where the VPC pressure sensor is usually plumbed into).
Have a friend bring the engine speed of the car up to 3500 rpm. Run your vacuum line to the direct-port source at the throttle body. Submerse the other end in the bottle of transmission fluid. Keeping the tube slightly pinched, regulate the flow of fluid into the engine as your friend works the throttle to keep engine speed between 3500 and 4500 rpm. Large puffs, no, LARGE CLOUDS of smoke will begin to emit from the tailpipe and possibly under the hood (if you have any exhaust leaks).
After half of the bottle is used, repeat with the water using half of that bottle. After you locate the vacuum port on the driver's side of the manifold, repeat the process. First use the tranny fluid, then follow with the water.
When you finish this process which will remove the carbon buildup within the cylinder, follow the manufacturers directions for the engine oil "motor flush." Follow with an oil change and replace the plugs (the chamber cleaning process can foul the plugs).
That's it, you're done.
Now, go out and drive the car and feel the power. If your valves were gummed up before, it'll feel like these an extra 20 ponies under the hood as throttle response will be tremendous.
Since my car had so many miles on it, I repeated this process at the next oil change. For the heck of it, I did a cylinder leakdown test. The results were amazing...two percent leakdown in each cylinder. Typically, cars with this kind of mileage would be happy to see 6 to 12 percent.

(NOTE: DO NOT attempt this if you don't know what you are doing! You can suck too much fluid in too fast, and "hydrolock" your engine (fluid is incompressible - too much, and it is like trying to crush a rock), which can destroy valves, rings, pistons, or the head or block. The fix above does NOTHING to clean the lifters, it is cleaning carbon off of the valves, which can cause a ticking sound similar to that of noisy lifters. Use fuel system cleaners instead -TS).

if my lifter situation gets pretty bad (it quiet enuff now) i'll probably explore this technique!
. Like no lifter noise, not even for a few seconds after startup. I dunno when it happened but it was so gradual that I didn't notice the change. I monitored it over yesterday and today and WOW, hardly any noise at all.
