FWIW, i used that in my eldorado'* 500cid, with 50k on it, it had valvetrain noise similar to yours, but i think that was in part from sitting with used oil in it for 10+ years.

i did 3 oil changes at 750-mile intervals, which helped somewhat, but not totally.

I used a can of that, followed the directions, and the ticking is gone even at cold start-ups.

The difference I'd be worried about is the tolerances in the 3800 would probably be much slimmer and, as previously mentioned, some sludge/varnish breaking loose could clog something up.

Why didn't you say you had lifter tick in the first place? That stuff in the can is nothing more than a strong solvent; you can do the same thing with gasoline. 1 pint of gasoline in the crankcase usually does the trick. Just let it idle with it in there. After about 30 seconds, the tick should go away. And after about 10 minutes, the gasoline will be gone too; it'll go out the PCV system in the form of vapors.

Lifters go flat because either their inlet holes get blocked from a piece of debris, or there'* not enough oil pressure to get to them. If it'* just one lifter ticking, then usually it'* a problem with just that lifter.

Marvel Mystery Oil? It is a very thin trans fluid and it, IMO, does a nice job of pulling crap out of the engine..

If you do go with any of these options, I would wait until she needs an oil change, use conventional oil and the existing oil filter. Run whatever you think is best, or all of them and change the oil immediately using what you were before; Mobile 1 and your filter. (good oil, IMO). I would not go and drive the car with any of these suggestions in the crank (except for the gas or the Marvel Mystery Oil). Good Luck and keep us posted!

That is all it is, I used lots of it this summer in my gas tank, only way my fuel gage would work for some odd reason.
Mechanic in a can will never fix a problem, only prolong things to come, at best.

I know it can't FIX it and prolong it is EXACTLY what I'm trying to do. I can't STAND the lifter tick, I just need a quick fix for it. You would not believe how loud it is. Its awful.

Ok, thanks for the bunch more info guys. You've given me alot of options, I see Marvel Mystery Oil *Kerosene*, Gasoline, and the flush I mentioned. Now IMO, this Marvel Mystery Oil and the CRC stuff sound the most reputable *no recourse on putting gasoline in my crankcase*, Now if someone could tell me, which, between the CRC and MMO would be the most effective in cleaning out my crank case EFFECTIVELY and be the least damaging?

I've always used kerosene. Haven't had problems yet.

The only thing i use and would suggest is

http://www.seafoamsales.com/motorTuneUpTechGas.htm


How Many Mechanics Use SEA FOAM
In Tune-Up of 4 Cycle Gasoline Carbureted or Fuel Injected Engines
Autos, Trucks, and Tractors

1. With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes. If severe carbon build up is apparent, use more Sea Foam as previously directed. Make sure exhaust is well ventilated when using Sea Foam in these various ways as fumes will be extreme for a short time.
2. Pour 1/3 to 1/2 pint into oil crank case to clean rings, lifters, dirty parts and remove moisture.
3. Pour 1/3 to 1 full pint into fuel tank to clean injectors, carburetor jets, fuel lines and remove moisture.
4. Immediate Results: Smoother idle, increased R.P.M.'* better throttle response and improved performance. See label on can for detailed results for use in each area.

FUEL TANK, CARBURETOR, INJECTION and OIL CRANKCASE.
For Peak Performance, Use SEA FOAM Every 2,000 to 5,000 Miles

* A 100% pure petroleum product for use in all gasoline and diesel type engines, both 2 and 4 cycle. OXYGEN SENSOR SAFE.
* Cleans dirty engine parts internally by removing harmful gums, varnish and carbon. WORKS AND PERFORMS INSTANTLY.
* Removes moisture from oil crankcases and fuel tanks.
* Stabilizes and conditions fuels. Use for engine storage.
* Cure hesitations, stalls, pings and rough idle due to carbon buildup.
* Helps pass emissions test. EPA Registered.

When Used Thru Injection or Carburetor

* Cleans carbon build up
* Cleans intake valves and pistons
* Gives smoother idle
* Cleans catalytic converter odors
* Cures hesitations and pings
* Restores power and pickup
* With warm engine running, SLOWLY poor 1/2 pint through carburator, throttle body or direct manifold vacuum line that will feed ALL CYLINDERS. Possible sources are P.C.V. valve or brake booster line. Turn ignition off. Restart engine after 5 minutes. Be sure exhaust is well ventilated. Fumes will be extreme for a short period of time.
* For use in injector cleaning machines, use 50% SEA FOAM and 50% fuel.
* Fill diesel filters with SEA FOAM to clean injectors fast.

When Added to Crankcase (Oil)

1. Frees sticky lifters and rings
2. Increases R.P.M.'* vacuum and compression
3. Cleans dirty parts
4. Removes moisture
5. Cleans PCV valve systems

One pint treats 10 quarts of oil (avg. 1 1/2 ounce per quart).

When Added to Fuel Tank

* Cleans fuel injectors and carburetor jets
* Cleans carbon as you drive
* Lubricates upper cylinders
* De-ices and removes moisture
* Diesel full conditioner and anti gel
* Stabilizes fuel

One pint treats 8-25 gallons of fuel (average 1 ounce per gallon).

In Injector Cleaning Machines

Add a 50/50 blend of fuel and SEA FOAM into injector cleaning machine. Run directly through the fuel rails to clean injectors fast. Add SEA FOAM to your fuel tank to clean injectors as you drive.
