Will LC20 quiet down lifters?

[psudaytona]

I was searching and couldn't find a direct answer. I believe its the lifters on my #1 cylinder in my 2.5L engine. It taps constantly. I used a stethoscope and it really seems to be coming from the top of the engine(right under the valve cover). Its there from startup to shut down so I don't think its piston slap. And its there only at idle to about 1750rpms. Usually its valve train components when its tied to the low speeds.
A set of rebuilt lifters for this car is only 20.00 for all 8 but I don't really have time right now to tear into this as I have college finals until the 20th of Dec and then all the christmas stuff with the family.
I was hoping LC could maybe clean them, and the rest of the engine enough to quiet them down.

I really don't like the idea of running Rislone or MMO in the crankcase.

Thanks guys!

IF the lifter is malfunction due to build up like varnish or other deposit then LC20 will help. If the lifter is worn out nothing you put in the oil will ever help!

Yeah, I am hoping its being caused by a buildup. At least maybe quiet it enough over the short term until I can get a chance at replacing the lifters.

Instead of playing guessing game, perhaps you could do the following for us?

(1) what type of car/engine is this?

(2) Have you try taking off the valve cover and investigate to see if it has something to do with collapsed lifter (it happens you know) or something mechanical?

Esp. (2) please find that out first before you jump into conclusions for using LC, Rislone, Wynn's, kerosene, etc.

1) Dodge Daytona 2.5L I4 engine. Hyd adjusted valve.

2) I used a stethoscope on the engine and the sound is directly coming from atop of cylinder 1. I live in an apartment and we are not allowed to do under the hood maintainence work so I can't pull the valve cover on it. I do all my work in my uncles garage but its unavailable for at least a month right now.

I 2nd the vote for pulling a valve cover off for inspection.

But, you can add anything you want to the oil.
Whats the year/mileage/maintenance history/oil type and weight in use?

Sorry, I should have included all that data. My bad.

1992, it is at 184K miles on the same engine. I suspect it has a poor history since alot of stuff is BADLY worn, struts and shocks were shot, had to put on new brake pads, transmission had a long running leak that ultimately damaged it(I am rebuilding another a413 unit for it). Had to do a bunch of other small stuff like vac lines, tune ups.

Its currently running 10w30. its what I always changed it with, don't know what the previous owners used, as I got it at a local used dealer. As of now its running Castrol StartUp with a walmart brand filter. Also I have about 1.25 bottles of SLOB in it, and like 8 ozs of VSOT. I am about 2000miles into my current OCI.

It made this sound since day one, my neighbors 1992 dodge shadow makes the same noise just MUCH softer and her engine has only 40K on it.

Hopefully, LC will maybe quiet it a tad until I can get over to my uncle's place. Either way, I think the engine could use a good cleaning anyways, I bought a bottle of ARX a month or so ago but was gonna use it come spring time.

would a treatment of LC20 be a better choice than Auto-RX?

I was just going to suggest AutoRX. I do use LC20, but I found that AutoRX did quiet noisy lifters on my Harley. At first I the lifters got louder, but they calmed down after awhile and now all I here is valve noise (that I couldn't hear over the lifter noise so it improved quite a bit).

You might want to consider that as an option as well.
