Most likely not. I've heard of additives, or valve cleaning products to lessen the knock... but if its loose/broken rocker arms/lifters/valve springs/valve clearance problems then the only way is to actually replace/ recondition those parts. Thinking that the problem is gone after using those products could cost you in the long run or even worsen other parts in the engine.

How do you tell if you self ajusting slack ajusters are wore out?
Vague question.. If you are asking about self adjusting valve lifters, here you go. Lifters that are wearing will begin emitting a slight ticking noise with the engine running.. Somewhat louder when cold, then lessening as the engine warms up due to the expension of the metal parts. When the lifters are extremely worn, a loud "clacking" noise can be heard with the engine running.. In most cases the lifter internal oil check valve is either dirty or worn.. In some instances, the bottom of the lifters can become concave with high mileage engines which also indicates a worn out camshaft.

Why does your 2002 Dodge Caravan clatter and have dirty oil?
When you say "clatter" do you mean lifter/valve noise in the top end under the valve covers? Dirty oil will make the top end noisy because it is not lubricating enough to protect the components. Or the oil pickup is clogged. Best to change the oil if you know it is dirty and see how it sounds after that.

How do you adjust Plymouth 318 valve?
You don't. The rocker arm assemblies just bolt down, the hydraulic lifters self adjust. If the valves are clacking, something in the valve train is worn out.
What is the intake valve tightening sequence on an 85 Chevy 305?
start in the middle go side to side and work your way front and back There is no 'sequence'. Hydrolic intake and exhaust valves are adjusted while the engine is warmed up and at idle. The rocker arm stud nut is tightened until the clacking sound associated with that valve is silenced and then add an additional 1/4 turn. If no clacking is observed with a given valve, undo the rocker arm stud nut until clacking is heard. Once clacking is heard, proceed as described above for a valve which was clacking to begin with. Continue this procedure until all valves, exhaust and intake, have been addredded. Job done. If you are dealing with a solid lifer cam, which was not a stock item in 85', again, there is no sequence and all valves adjustments are done while the engine is 'cold'. The gap between the rocker arm and valve (intake or exhaust) will be around .020" +/-. Check with Chevorlet for exact specifications. Turn the engine, using the starter motor, until the rocker arms are loose at a give cylinder and make the approate valve lash adjustment between the rocker arm and the valve. Repeat until all cylinders have been addressed. Job done.
Would a low pressure turbo give a good blow off valve noise?
All turbos will give a blow off valve noise but the higher the pressure in the boost pipes (eg) higher boost, the louder the blow off noise and if you have a recirculation valve remove that with a remap and the noise will be even louder.

Why would you hear a ticking noise in your Saturn 2001 L300 v6 after changing the ERG valve?
The Saturn V6 has always been a little "vocal". A little valve noise is quite common and most likely, if it's valve noise, you probably just didn't notice it before the repair. Many people become hyper-aware of sounds after the vehicle has been repaired. The Eco-Tech engine is well designed and can be expected to last a long time if properly maintained. It's economical, reliable and powerful. However, if it's NOT valve noise, there could be some other problems. Try to isolate the source of the sound to see which component is responsible.
